The Zero Car is a testing platform and chassis for the Wheel Robots project. Zero Car is a customizable and modular platform that houses the energy source (batteries), control system, and mechanical connections to smart wheel assemblies. The Zero Car will also be the future testing platform for our virtual towing simulation. Zero Car comes in multiple sizes: bicycle, tricycle, 4-wheels, and mini. The mini-Zero tests four omni-directional wheels attached to a chassis and wireless RC controller.
