TatamiRacer is a tiny autonomous driving car based on the "TAMIYA MINI 4WD" kit. It can operate within the space of a single "Tatami" mat, approximately 1.8m x 0.9m. The car uses "Donkey Car" software for deep learning and self-driving control. Interestingly, the Japanese word "Tatami" also brings to mind convolution operations in neural networks.
