I built this robotic arm specifically as a research platform for my project, “Comparative Study of Adaptive Robotic Arm Grasping with Human-Like Capabilities.” It is designed to test and compare different adaptive grasping methods (fixed settings, vision-based adjustment, and tactile feedback) across different cup materials. At the same time, I also want to open-source the arm so other makers and students can build it, reuse it for their own experiments, and extend it with new sensors, control logic, or applications.
