TBT (Timing Belt Tank)
thingiverse
When assembling the robot, I realized that the timing belts resembled tank treads when flipped inside out. Inspired by small robots' fun factor, I opted for a chassis based on 140XL timing belts. After purchasing parts from eBay, I discovered that 300RPM motors had insufficient torque, so I recommend these alternatives: [motor links]. I shared my project details on LMR at [project link]. Assembling the robot requires printing two sets of each side and end part due to their symmetrical design. Attach two timing belt pulleys with tape and secure them with a M3 set screw. Assemble rollers with ball bearings inside, gluing the halves together; note that these are not symmetrical during mounting. Ensure M4 bolt holes in the base plate and end pieces are tapped for proper attachment.
