Abstract

A robotic vehicle may include control circuitry configured to execute stored instructions to direct operation of the robotic vehicle on a defined area, and an electrical resistance sensor in communication with the control circuitry. The electrical resistance sensor may be configured to detect motion indicative of a lift event and a collision event using a single sensor.
