Robots & toys / Supervised experiment

Robot dog video controller and autonomous ball approach

Custom laptop video controller, sensor access and software that locates a beach ball, approaches it and moves it; a natural-language controller was also demonstrated.

What the hardware does

Custom code uses the robot’s camera, sensors and motors to approach and move a ball.

How the agent helped

Anthropic's firsthand experiment says the robot was controlled with a program largely written by Claude and describes the code-writing, sensor and controller tasks performed by Team Claude.

Before you build

Full autonomous fetch was not completed. Keep a human supervisor and a clear operating area; collision hazards remain.
