The present disclosure relates to an articulated self-propelled robotic toolwith first and second platforms, each comprising a wheel setdriven by motors. A link arrangement connects the first platform to the second platform at a turning axis. A driving error is determined by recording a driving input to the motors and a resulting movement parameter, comparing the resulting movement with an estimated resulting movement which is based on the driving input. Slip is detected using the driving error.

Robotic working tool

Described are an on board unit (OBU) and a method to control an OBU within a communication zone of a road side unit (RSU), said OBU can be set into an active mode and a sleep mode. Said OBU is set into sleep mode upon receiving a release command from said RSU, and the OBU electronics are shut down so no or a minimum of power is consumed, and is set into active mode when entering said communication zone. A communication unit of said OBU is thereby powered such that the OBU can communicate with said RSU. Said OBU can be set into a tracking mode by said RSU, whereby in said tracking mode at least said communication unit is shut down and a timer is activated in said OBU, such that said OBU can restart said communication unit within a specified time limit from when it is shut down.

On board unit with power management

Embodiments of the present invention relates to a vehicle transponder comprising an active radio unit, an antenna, a wake-up unit and a power directing means which has a first port, a second port and a third port, where the power directing means is arranged to direct power from the first port to the second port and/or the third port. The antenna is connected to the first port and the second port is connected to the radio unit. Furthermore, the third port is connected both to a power detection port at the radio unit and to the wake-up unit, such that during a first mode of operation, a part of a signal that is transmitted from the radio unit to the antenna is coupled from the second port to the third port and further fed to the power detection port.
