It’s based around the ubiquitous Arduino Uno, paired with a motor control and I/O shield for more connectivity. The robot uses treads for locomotion—each side has two wheels wrapped in a belt ...

But what if there was a way to bridge that gap? This robot arm guide offers a guide to building a mini robotic arm using Arduino, complete with 3D-printed parts and easy-to-follow instructions.

The ESP32 cam itself is mounted on the “head” on the robot for a good field of view. Meanwhile, it communicates with a separate Arduino Nano which is charged with generating pulses to run the ...
