Semi-autonomous safety envelopes preventing remote operators from colliding with furniture, people, or stairwells.
Downward-facing infrared cliff sensors detect stairwell drops, instantly overriding remote operator forward commands. Ultrasonic and depth sensors create a 360-degree virtual bumper, smoothly sliding the robot past doorframes.
At the end of a session, the operator simply clicks 'Dock'. The robot identifies the infrared charging station, reversing smoothly onto contact pads with millimeter alignment.
