2WD robotic car chassis kit with DC geared motors and encoder discs

The 2WD Robotic Car Chassis Kit is the ideal starting platform for anyone building their first wheeled robot. The dual-layer acrylic chassis is lightweight yet rigid, and the included 1:48 ratio DC geared motors provide smooth, controllable drive at 3V–6V. With encoder (velocimeter) discs included, you can add speed sensing for closed-loop control — perfect for line followers, obstacle avoiders, and remote-controlled robots.
