Baymax Mini (tentative)

This is a personal open-source project focused on soft body robotics. Although the detailed design is still in development, the project’s high-level direction prioritizes intrinsic safety. The manipulator features a soft continuum mechanism to maximize flexibility and minimize inertia. Mobility is achieved through a three-actuator spherical drive system, enabling omnidirectional movement. To ensure safety during power loss, the design incorporates a low center of gravity (passive stability); this prevents the robot from toppling over, protecting the home environment and vulnerable occupants, such as baby and small children.
