Its a great little robotics platform. Everything works as expected. The robot construction quality is better than expected. Very well designed.
Got a Pro version, it's very easy to put together, and it works great.
Would be great to have brushless motors and more GPIO access through the plastic shell in ProtoBot v2
It is a compact, very well designed RC-like robotic car with endless possibilities for those with active imaginations. Inspirational and creative in a small form factor. Innovate and enjoy!
