METHOD AND APPARATUS FOR OBJECT FOLLOWING ROBOT USING UWB AND ODOMETRY-BASED RELATIVE POSITION ESTIMATION
Disclosed are a method and apparatus for enabling a robot to follow an object by using distance measurement data and odometry data through ultra-wideband (UWB) to estimate a relative position of a target in a robot center coordinate system. The method comprises initializing a robot's own object following algorithm according to an object following request; transmitting a single-sided two-way ranging (SS-TWR) poll message; receiving a single response message in response to the SS-TWR poll message from the object, the single response message including second odometry information of a second odometry measurement device of the object; estimating a distance to the object based on a round trip delay calculated by an SS-TWR method; predicting a position of the object based on the second odometry information and first odometry information of the first odometry measurement device; and correcting the position of the object based on the estimated distance.

SENSOR DATA GENERATION FOR CONTROLLING AN AUTONOMOUS VEHICLE
A method and an apparatus for generating sensor data for controlling an autonomous vehicle in an environment is provided, such as driverless transport vehicles in a factory for example. Sensor positions of static sensors and the sensors of autonomous vehicles are defined in a global coordinate system on the basis of an environment model, such as a BIM model for example. Sensor data is centrally generated in this global coordinate system for all sensors as a function of these sensor positions. The sensor data is then transformed into a local coordinate system of an autonomous vehicle and transferred for controlling the autonomous vehicle.
METHOD, MOBILE DEVICE AND CLEANING ROBOT FOR SPECIFYING CLEANING AREAS
A method for specifying a cleaning area to a cleaning robot without an in-built map provides a hand-held mobile device capturing a two-dimensional code label arranged on a top of a cleaning robot parked on a charging base, and obtaining a positional relationship between the mobile device and the cleaning robot through the captured image. The cleaning robot is controlled to enter a cleaning mode under the guidance of the mobile device. With captured images, a user can specify an area within the environment for cleaning, and through a touch display screen can control the cleaning robot to go to the specified cleaning area for cleaning. The mobile device and the cleaning robot employing the method are also disclosed.
System and method for controlling a self-propelling lawnmower
A method and a system for controlling a self-propelling lawnmower including the self-propelling lawnmower having a control unit and at least one sensor, a boundary wire and a signal generator. The self-propelling lawnmower moves across an area surrounded by the boundary wire. By encoding a data frame with a recognition code in an alternating current that is Direct Current, DC-balanced and that is randomly transmitted within a predetermined period of time, by means of the signal generator, to the boundary wire a system robust against interference is accomplished. The data frame burst is received by a sensor and decoded by a control unit in the lawnmower. By comparing the received recognition code with a stored recognition code, the control unit determines that the lawnmower is on the inside of the boundary wire if the received recognition code matches the stored recognition code, and on the outside if the received recognition code matches the inverse of the stored recognition code.
