Roli is a very customizable planetary rover style robot kit, with 13 female ez-bit connections for additional ez-bits. Much like a space exploration vehicle, Roli was designed to be a workhorse and move across different surfaces. With a 7.4v LiPo battery powering 2 motors, this robot has enough torque to tackle tough terrain. The wheel and tread heights are adjustable, so you can modify its ground clearance. The included ezrobot ez-bv4 Camera adds impressive vision tracking capability.
