The Keyestudio 4WD Robot is one of the most popular Arduino robot kits for schools and clubs. Students assemble the chassis and electronics, then work through 17 projects: blinking LEDs, adjusting brightness, line tracking, obstacle avoidance, IR remote driving and finally a multi-purpose Bluetooth smart car. The motor driver expansion board also lets students add their own sensors and modules.
