A method of navigating an autonomous coverage robot on a floor includes controlling movement of the robot across the floor in a cleaning mode, receiving a sensor signal indicative of an obstacle, rotating the robot away from the sensed obstacle, determining a change in the received sensor signal during at least a portion of the rotation of the robot away from the sensed obstacle, and identifying the sensed obstacle based at least in part on the determined change in the received sensor signal.

PROBLEM TO BE SOLVED: To reduce a monitoring burden of an operator who remotely operates an autonomous travel robot.SOLUTION: An autonomous travel robot 10 has a drive part 14 for moving along a prescribed route, an external environment acquisition part 12 for acquiring information of an external environment, a map storage part 18 for storing an environment map generated on the basis of the information of the external environment, a route setting part 22 for setting a movement route from the present location to a destination by an input from an operation terminal 50, and a behavior selection part 24 for determining whether to control the drive part 14 so as to avoid an obstacle or to output a signal for urging a remote operation when the external environment acquisition part 12 detects the obstacle in the movement route. An avoidance behavior storage part 20 stores operation information when avoiding an obstacle by remote operation, and the operation information is referred to in the case that the behavior selection part 24 avoids the obstacle.

The invention provides a vehicle body interface system, comprising: a wireless network communication interface which is used for transmitting an operation command of a remote server or a terminal to avehicle control unit, wherein the operation command includes control command information or cleaning business command information such that the vehicle control unit performs controlling according tothe control command information or performs cleaning according to cleaning business command information, or transmits vehicle state information and cleaning business information forwarded by the vehicle control unit to the remote server or the terminal; an emergency brake signal input interface, wherein one end of the emergency brake signal input interface is connected with an emergency stop button, the other end of the emergency brake signal input interface is connected with the vehicle control unit and a motor controller, and the emergency brake signal input interface is used for being triggered to transmit a trigger signal respectively to the vehicle control unit and the motor controller such that the motor controller controls a motor to stop operating according to the trigger signal, and that the vehicle control unit enters an emergency brake mode according to the trigger signal. Therefore, third-party operation of vehicles is achieved.

PURPOSE:To make a detour around an obstacle without any complicate steering operation by providing a car body side with an automatic steering control means for obstacle detouring which is operated on the basis of a stored obstacle detour pattern. CONSTITUTION:This controller is equipped with a steering control means 101 for remote control which operates an actuator 8 for steering on the basis of instruction information generated by a steering instruction means 100 provided to a transmitter and the automatic steering control means 103 for obstacle detouring which operates said steering actuator 8 on the basis of run path information which is stored in an obstacle detour pattern storage means 102 and used for steering while a detour is made around the obstacle. Those steering control means 101 and 103 are switched on the basis of instruction information generated by a starting means 104 for automatic obstacle detouring provided to the transmitter 11a to control the operation of said steering actuator 8.
