Releasing the emergency stop

After booting and during normal operation it can happen that the emergency stop gets issued due to a number of things (even non critical), e.g.:

• Someone stepping too close to the robot (even if the robot does not move)

• The robot drives too close to an obstacle

• The wireless emergency stop gets disconnected

• Someone presses the emergency stop

In order to re-activate the robot, the wireless emergency device has to be reconnected and the robot’s modules have to be reset. Please follow these steps:

Warning

Remove all obstacles and check surroundings first
