These are building blocks for making a robotics electric vehicle in different sizes. Ideal for autonomous/self driving and general prototypes etc.

It uses 25mm steel tube and inserts with 8/13mm bolts/nuts. The wheels are from Bauhaus with aluminium cores, kind of for a wheelbarrow. 22mm skateboard bearings are used for the steering setup.

Other smaller wheels like from a mountainboard can also be used.

The steering works with a servo, and the current design has a limit around 50kg for practical steering with the chosen servo. But another design for the steering will change this limitation. I have a design using a stepper motor, ask if you are interested.

The rest of the design is proven to be able to carry over 200kg in a 1m X 1m size setup with the side tensioners.

The drivetrain used is the mid drive system I also designed: https://www.thingiverse.com/thing:2589187

The whole motor unit is supposed to be able to slide to enable automatic belt tensioning. Springs s
