Self-balancing Car 平衡车

The Self-balancing car I built in Freescale Smart Car Contest in 2013.The car is modified from a RC car,which is a designated model by the contest.In this model,some of the parts are machined using my CNC router.I also made some PCBs and programmed the firmware. If you want to watch the video of this car running,please go here: https://youtu.be/HWOfQ2LwfWA And go here if you want to know how I built it: http://lichaoma.com/2015/11/17/self-balancing-smart-car-based-on-freescale-mc9s12x128/
