Abstract
A system for controlling a robotic arm is disclosed. The system includes a robotic arm including a surgical tool, a tool driver, and at least two sensors disposed on the robotic arm to redundantly monitor a status of the robotic arm and to verify an operational parameter of the surgical robotic tool. A central control circuit is configured to measure a first physical property of the robotic arm based on readings from the first sensor, measure a second physical property of the robotic arm based on readings from the second sensor, and determine a status of the robotic arm based on the first and second measurements of the first and second physical properties of the robotic arm.
