SPARTA

Servo Powered Autonomous Rough Terrain Automobile

This is SPARTA (as of 3/14/2021), a heavy, 3D-printed Unmanned Ground Vehicle and dropping mechanism. If you desire a more in-depth view of the design, check out the CAD latest CAD file (make sure you turn the visibility on for the correct parts).

Design Rationale:

• Big wheels spanning the whole UGV cushion falls and make driving over rough terrain easier (it still has trouble because of how small and comparatively light it is).

• Sled (and pin) in the back acts as a parachute attachment point and a stabilizer so that the inner body doesn't rotate instead of the wheels.

• ABS plastic allows for non-brittle impact resistance and wear-proof parts.

• Velcro permits the simple reorientation of any components while achieving a strong bond nevertheless.

• Heavy-duty metallic servos provide a huge amount of torque and a strong connection point for the wheels.

• Small screws provide strong connection points while allowing the simple disassembly of SPARTA.

• The back wing (not shown in the picture) is an addition to the sled that prevents it from sinking into tall grass and mud by increasing the surface area.
