Robotling2

Robotling2 is a small, simple 6-legged robot using the new Raspberry Pi microcontroller RP2040 as brain. To move around, it uses a simplified tripod walk that requires only three servo motors - inspired by a 20 year old book called "Insectronics".

Features

• Robotling2 PCB hosts a RP2040 Pico
• Board controls 3 servos and features a "sensor port" with connectors for 3 analog sensors (5V-tolerant), 1 digital I/O, I²C, and UART, as well as 5V and 3.3V power.
• Fits an optional color display (Pico Display Pack)
• All parts 3D printed (except battery case)
• Requires only 3 micro servos (e.g. Tower Pro MG90)
• Runs on a ~1Ah 1-cell Lipo battery
