This is Part 8 of the series. The robot can move with primitive gestures, but those are deliberate, literal motions. For expression — reacting to good news, bad news, a greeting, a joke — I want something richer: a library of ~80 pre-choreographed emotion moves that the agent picks from to match the mood.
The LeRobot Follower arm is subscribed to an IoT Topic that is being published in real-time by the LeRobot Leader arm over AWS IoT Core, using a Seeed Studio XIAO ESP32C3 integrated with a Seeed Studio Bus Servo Driver Board, the driver board is controlling the 6 Feetech 3215 Servos over the UART protocol.
In this video I demonstrate how to control a set of Hugging Face SO-101 arms over AWS IoT Core, without the use of the LeRobot framework, nor using a device such as a Mac nor a device like Nvidia Jetson Orin Nano Super Developer Kit. Only using Seeed Studio XIAO ESP32C3 and AWS IoT.
