Constructed "Turn Bug," a four-legged robot

Features a central rotating joint allowing for twisting movement, enhancing maneuverability.

Crafted with a dual-chassis system, one part remains stationary while the other rotates, simulating the turning motion of a living organism.

Used Solidworks for design.

Utilizes a Raspberry Pi for intelligent control and bus servos for precise actuation of the legs and rotational movement.

The rotational movement is achieved by a servo motor attached to one part of the chassis, which drives the other part to rotate around the central joint

The chassis is constructed from laser-cut materials for precision and ease of assembly.

All moving components, brackets, and mounts are 3D printed to fit the custom design requirements.

Successfully achieved lateral movement at a speed of 15 cm/s with the four-legged design.

Currently refining the central joint mechanism to enable forward motion.

Ongoing development to enhance the robot's maneuverability and locomotive range.
