From the project

turn your phone into a robot running SLAM with two motors, two control boards, and a bluetooth chip

Mobile phones and mobile robots have many common requirements:

- performant sensors (cameras, IMUs, LiDAR, GPS) and sensor fusion - networking capabilities (WiFi, Bluetooth Low Energy, LTE) - energy efficiency

What if we turned the iPhone into a robot?

- exposes the core sensor data through iOS APIs - Camera - LiDAR (iPhone Pro 12+) - IMU - runs WASM bytecode using statically compiled WAMR iwasm - communicates with ESP32 over BLE to control motors
