Abstract
A robot includes a robot arm, a force sensor that is provided on the robot arm, and a processor that is configured to execute computer-executable instructions so as to control the robot and process a sensor output of the force sensor. The processor is configured to: set an offset calculation period after resetting the force sensor; and perform an offset calculation operation for calculating a value based on the sensor output during the offset calculation period as an offset and a correction operation for subtracting the offset from the sensor output at the time of force detection after the elapse of the offset calculation period.
