The 2WD Smart Mini Round Robot Car Chassis DIY Kit with DC Motors, Wheels and Caster Wheel is a compact and reliable robot car chassis kit designed for robotics learning, Arduino projects, and STEM education. It features a 135mm transparent acrylic base that is lightweight, durable, and easy to assemble. The round chassis design helps distribute weight evenly, allowing the robot to move smoothly while reducing the chances of getting stuck at corners. Its transparent acrylic plate also makes wire routing and component placement clearly visible, making assembly and troubleshooting much easier.
This 2WD chassis kit includes two dual shaft BO DC motors that operate on 3V to 6V DC and deliver approximately 90 RPM. These motors are ideal for projects that require controlled and accurate movement, such as line follower and obstacle avoidance robots. The dual shaft design allows encoder discs or additional wheels to be attached on either side, making it suitable for users who want to add speed or position feedback. The kit also includes two wheels and a caster wheel, providing stable movement on flat surfaces.
The 2WD car chassis kit does not include a motor driver or controller board, giving users the flexibility to choose their preferred electronics. To control the motors, simply connect an L298N or L293D motor driver with an Arduino or ESP32 development board. Available from StemVolt, Make it Arduino chassis kit for beginners and students looking to build programmable robots while learning motor control, embedded systems, and robotics fundamentals.
