What If Your First Robot Fit in Your Palm? ProtoBot is a tiny robotics platform built around an ESP32-C6, with four N20 motors, proximity sensing, a 9-axis IMU, RGB lights and a breadboard for adding your own electronics. You can drive it from your phone, make it avoid obstacles, draw shapes, log sensor data or write your own Arduino code. The really nice part is that the body, accessories and software are open source. You can 3D print the shell and add things like a thermal camera, air-quality sensor, humidity sensor, camera mount, tank tracks or a grabber. It feels like a small robotics playground where you can start simple and keep adding hardware. What would you add to it first?
