What it can do
Written by Robotheca from the project's documents.
- Moves on a four-wheel chassis with omnidirectional wheels
- Follows a person using a camera and YOLO26 object detection
- Controlled via web interface with real-time video stream
- Controlled via Xbox gamepad for chassis and robotic arm
- Controlled via natural language using Picoclaw AI assistant
- Performs imitation learning tasks
- Supports speech interaction with text-to-speech and large language models
- Supports emergency stop and lock mechanism
Works with AI
Found by Robotheca in the project's files at commit 7c17ed6, its robot.yaml and Robotheca's notes on its documents. Never guessed; Robotheca doesn't run the code.
Uses a large language model
