Meet Chaser

A teammate that
never gets tired.

Chaser runs onboard vision in real time on a high performance NVIDIA edge module. Sensor fusion across cameras and ultrasonic input lets it spot balls and steer itself across the court with a precision Smart PWM drive. A foldable hopper holds up to 60 balls and collapses flat for storage.

No remote required. Drop it on the court, hit the start button, and keep playing.
