1. INTRODUCTION Robotic carving has been a major advancement in the larger context of digital fabrication, and it is a combination of robotics, computational design, and material science to create very accurate and customizable shapes. With the growing number of educational institutions incorporating highly innovative technologies into their curricular programs, robotic carving is becoming a more and more popular method of creating, as well as a driver of the change of pedagogical perspectives. Its usage indicates a wider change to more towards experiential, inter-disciplinary, and technology enhanced learning environments in which students are actively involved in processes of design and fabrication that can be seen to reflect professional practice. The emergence of robotic carving can be interpreted in the development history of fabrication technologies, the history of manual work and mechanical early mechanisms, then CNC machining, and, most recently, multi-axis robotic arms. Robotic carving is flexible, adaptable, and scaled unlike the traditional subtractive methods Tang et al. (2023). It helps users to cut intricate geometries, manipulate a variety of real world materials and experiment with a form that would be hard or even impossible to realize with conventional tools. These features make robotic carving become a precious tool in a variety of uses, such as architecture, art and design, engineering, and product development. The usefulness of a robotic carving is not limited to its technical functionality in the context of education. It is now being embraced by universities and design institutes as a way of promoting more meaningful learning experiences through the involvement of students in project-based and iterative workflow Zhong and Xia (2020). Using the combination of robotic instruments, learners become directly exposed to the entire design-to-fabrication process: they can observe the digital design and modeling phases as well as the physical stages of testing and toolpath creation and execution. This participatory experience promotes problem solving, critical thinking and creative exploration as well as providing a physical correlation between digital manifestations and physical results. Robotic carving can also be closely related to the modern-day pedagogical theories, and especially to constructivism, which places the emphasis on learning through doing, reflection, and personal meaning-making. Through engaging with robotic systems, the students develop knowledge as they experiment with their designs and see what happens as a result of their design choices and use this knowledge to improve their processes Channa et al. (2021). Robotics integration into the studio and laboratory environment is another technology that can be used to support STEAM education programs, combining technical capability and artistic or conceptual growth.

Figure 1 Overview of Key Components in Robotic Carving and Pedagogical Theory Students learn a rich and varied set of skills as they encounter the technical challenges of programming and calibration with the aesthetic and functional issues; connecting the analytical and the artistic. In Figure 1, the components of robotic carving are accorded with pedagogical theory. Besides, robotic carving opens the possibilities of collaboration and interdisciplinary learning. Teamwork among students with an engineering, computer science, design, and fine arts background, is often necessary in projects. The interaction process resembles the practice of innovation in the real world, where complicated issues are solved by using the collective experience and interdisciplinary viewpoints Kubilinskiene et al. (2017). The common learning space leads to communication skills, flexibility and appreciation of the various methodologies. Simultaneously, the adoption of robotic carving raises some significant concerns in terms of security, availability, viability, and ethical utilization of automated technologies. Teachers should think about the way in which they can combine such systems in a responsible manner so that everyone can have equal opportunities and be ready to work in the future, where the role of automation will become more and more central Roberts et al. (2021). These issues underline the necessity of considered curriculum development and research that will also investigate the non-technical implications of robotic carving, as well as its consequences. 2. Technological Foundations of Robotic Carving 2.1. Components and mechanisms of robotic carving systems Robotic carving systems are made up of an assembly of mechanical, electronic and computerized parts that interact to perform complicated subtractive manufacturing operations. The central element of these systems is a multi-axis robotic arm, which, as a rule, has 4-7 axes and can be highly maneuverable and have a long reach. The end-effectors fitted on this arm include spindle motors, milling tools, or carving bits that can cut, shape and texture materials Tercanli and Jongbloed (2022). These terminal devices can be changed or tailored to the needs of the project, which enables the robot to be used with a wide variety of materials such as wood, foam, stone, plastics, and soft metals. The arm motion is controlled precisely by the motor drivers, servo motors and encoders to allow the robot to track the toolpaths. The operational reliability is guaranteed by safety systems which include emergency stops, collision sensors and protective enclosures Baharin et al. (2018). The material being processed is held steady by a supporting structure e.g. a fixed or rotating worktable and dust-collection units assist in keeping the environment clean and under control. The latest robotic carving machines have force-feedback extruded on the machines, enabling the robot to modify its pressure and speed depending on the resistability of the material. The vision systems can include depth cameras or laser scanners, which can be used to enable a real time tracking, scanning, or adaptive carving processes. A combination of these elements creates a highly integrated system that has the potential to convert digital models to accurate physical representations, and robotic carving is an essential device in the modern design and fabrication environment Hafni et al. (2020). 2.2. Software and Programming Tools Used in Robotic Carving Robotic carving is critically dependent upon specialized software ecosystems which interpret design intentions as machine-readable toolpaths. The design and manufacturing process of products usually starts with a 3D modeling system like Rhino, Blender, Autodesk Fusion 360 or SolidWorks through which designers produce digital geometries. The models are then sent to CAM (Computer-Aided Manufacturing) software such as RhinoCAM, Fusion 360 CAM or PowerMill, which produces initial toolpaths depending on the tool diameter, solid density, spindle velocity, and cutting plan Zizka et al. (2018). Most popular software platforms used in robotic carving include robotic programming environments such as Grasshopper (with such programs as KUKA|prc and HAL Robotics), ABB robots RoboStudio, and robotic carving simulator RoboDK, which deals with toolpath optimization and kinematic analysis. These are used by designers to simulate the movement of the robot in a virtual world and identify possible collisions as well as improving trajectories prior to real implementation. Simulation is a very risk aversive method that ensures accuracy and assists in streamlining time and material consumption Mwangi et al. (2022). Depending on the model of the robot, low-level programming can be performed with the help of such a language as RAPID (ABB), KRL (KUKA Robot Language), or Python-based APIs. 2.3. Precision, Automation, and Material Adaptability High precision and automation of a material processing are the distinguishing features of robotic carving. The multi-axis robots can also attain sub-millimeter accuracy as a result of built-in encoders, servo controls and sophisticated kinematic systems. In contrast to classical CNC machines that are only capable of linear motion, robotic arms are able to bring a workpiece in a variety of angles and excavate complex geometries, undercuts and organic formations with very high precision. This dimensional flexibility increases the possibilities of designing and allows experimentation on complex surface textures and sculptural shapes Kerimbayev et al. (2023). Automation is very important in improving productivity and minimizing human error. When a toolpath is developed, the same could be executed in the repetitive labor intensive jobs continuously without getting tired. Robots can modify speed, pressure and tool orientation dynamically based on automated calibration, real time monitoring systems and feedback loops, making them more consistent over several iterations Baccaglini et al. (2020). In more sophisticated implementations robotic systems may be linked to material-handling systems and so autonomous loading, carving and finishing can be done. Table 1 gives a comparison of studies involving the educational and fabrication use of robotic carving. The other characteristic feature of robotic carving is the material adaptability. The type of materials that robots can machine varies greatly, including soft foams and hardwoods, dense stone and engineered composites, by changing the speed of the spindle, the feed rate and the tool used.

3. Educational and Pedagogical Context 3.1. Role of robotic carving in design and engineering education Robotic carving has emerged as a powerful instrument in design and engineering education with the potential effect of giving students firsthand experience of high-digital fabrication technologies which are presently being employed in professional practice. Robotic carving bridges the gap between theory and practice by allowing learners to perceive the mutually reinforcing nature of the relationship between computational modeling, material performance and mechanical performance in the modern design studio and engineering laboratory.

Design and Engineering Programs Working with robots, students also acquire the understanding of motion planning, kinematics, structural concepts, and workflow optimization which are the concepts of contemporary engineering and design fields. Robotic carving is used in the field of design education to investigate the constraints of forms, geometry, and fabrication. Figure 2 has presented the paths that indicate the educational influence of robotic carving in design engineering. Students are able to test complex shapes, make prototypes, and make designs in an iterative way, thus developing an iterative attitude in solving problems Chang and Lan (2021). Meanwhile, engineering students have access to robotics, automation, and control systems and manufacturing processes that can prepare them to work in the automation, advanced manufacturing and product development industry. 3.2. Integration into Art, Architecture, and Fabrication Curricula Robotic carving is becoming part of the field of art, architecture and fabrication programs in order to develop the use of creative expression as well as technical proficiency. In art classes, the technology has been used to enable the student to experiment with sculptural objects, surface modulation and experimentation with materials at scales and levels of detail that would have been impossible in the traditional hand-carving techniques. Artists are able to operate in a cyclic manner, by combining both digital conceptualization and physical crafting, by extending aesthetic limits with computational generated geometries Solan and Shtub (2023). Robotic carving is crucial in architecture courses by allowing intent and constructability to intersect. Robots are used by students to create complicated spatial models, components of facades, and structural prototypes that embody new architectural tendencies focusing on parametric design and digital craftsmanship. The technology can assist learners to appreciate how design decisions can play with fabrication logic and learn to respect precision, tolerances and structural behavior. The curricula in fabrics lay stress on technical mastery, which trains students in toolpath design, machine programming, material handling and workflow management. These courses emphasize the practical competencies needed in the field of construction, industrial design and highly skilled manufacturing. Robotic carving is then taught as a learning tool to educate students as to how to translate abstract design ideas into objects to be produced by automated systems. 3.3. Skill Development Through Experiential and Project-Based Learning Robotic carving plays a major role in skill development as it complements experiential and project-based models of learning, based on hands-on engagement, iteration, and reflective practice. Students who have the direct experience with robotic systems are trained in technical skills that included computer programs, toolpath production, machine setup, and work with materials. These are skills that are developed in the process of cycle of experimentation where the learners design, make, test results and improve on their processes depending on the results of the tests. Experiential learning enhances cognitive knowledge through connecting theory with practice. The students can observe the process of conversion of digital models into physical objects and understand geometry, behavior of tools, and material properties better. This facilitates critical thinking because in this process, the learners have to anticipate possible fabrication challenges, troubleshoot and change their strategies on the fly. These problem-solving abilities form the core of the engineering as well as the creative disciplines. Project-based learning also encourages team work, team building and project management skills. Team-based working helps the students to organize tasks, share workload and to work within the complicated design-to-fabrication processes. This is similar to the professional settings where collaboration between disciplines is a crucial aspect. Psychomotor skills are also improved by robot carving, since the learners learn to control tools, set up materials, and use machinery safely and effectively. When the learners use different senses and motor skills, they develop confidence in their technical skills. 4. Pedagogical Theories Supporting Robotic Carving 4.1. Constructivism and hands-on learning Constructivist pedagogy is based on the idea that learning is an active, experiential, process whereby people construct knowledge by means of direct interaction and reflection. Robotic carving is similar to this philosophy since it will expose students to real, practical fabrication experience that can bridge theory and practice. The design-to-fabrication cycle has learners so that they are constantly experimenting with digital models, producing toolpaths and seeing what the machine does and how the results of the physical process look. This cyclical process helps them to build their knowledge by trial and error and progression as opposed to merely consuming information. In the robotic carving world, students are allowed to be involved in owning their learning, as they are allowed to make decisions regarding the choice of tools, preparation of materials, machine settings, and design plans. This agency encourages elaborated conceptual understanding and internal inquiry. When they deal with both the digital and physical systems, learners experience a collision with the real world parameters in the form of tool limitations, material inconsistencies, and fabrication tolerances. The ability to deal with such challenges leads to resilience and supports the constructivist idea that learning is a result of useful problem-solving. Reflection is also of primary importance. The results of every attempt to fabricate something are evaluated by the students, and discrepancies between the planned and real results are measured and modified to alter processes. 4.2. STEAM (Science, Technology, Engineering, Arts, Mathematics) Education Approach Robotic carving can be viewed as a potent stimulus in STEAM learning as it incorporates the scientific logic, fluency with technology, engineering tenets, artistic aptitude, and mathematical cognition into a unified learning process. The interdisciplinary nature of the modern design and fabrication practice can be presented as students work with robotic carving systems and simultaneously interact with several domains of STEAM. Science is developed by material experimentation where learners get to learn about the properties of density, grain structure, and resistance in machining. The process focuses on technology since students are involved in modeling, simulation, and the generation of toolpaths with the help of software tools. The concepts of engineering, such as kinematics, allocation of load, and optimization of processes, are inherent in the process of planning robotic movements and their real execution. The exploration of arts also gains the same significance because with the assistance of robotic carving, students can develop expressive shapes, sculptural texture, and aesthetically appealing artworks. Mathematics forms the basis of almost all the workflow steps, such as working out the angles and feed rates of tools, and the geometric transformations, and continuity of surfaces. The smooth connection between these areas reflects the conditions in the real world of problem-solving, where the innovation is based on the convergence of various disciplines. Teamwork and communication are other characteristics of STEAM education that are promoted by collaborative projects. 4.3. Cognitive and Psychomotor Skill Enhancement Robot carving plays an important role in the process of cognitive and psychomotor development of students, providing them with an integrated learning process involving the brain and the body. Mentally, the students will be required to examine the digital models, to foresee the machine behaviour, to design and determine issues that may occur in fabrication. These activities can develop superior level of thinking like spatial thinking, logical sequence, critical analysis and decision-making. Students are taught how to assess tradeoffs, get the best toolpaths and read the data in simulation, all of which demand longer term mental activities. Figure 3 demonstrates the way in which cognitive and psychomotor skills are improved with the help of robotic carving. Psychomotor skills are also reinforced because the robotic carving involves direct interaction between the learner and the materials, tools and machinery. Figure 3 |
