The paper deals with improving the reliability of mechanical components of the mobile robot Telerescuer. This improvement is realised by monitoring thermal parameters of some selected critical points of gearboxes and drives using the principles of IoT (Internet of Things) and by transferring all measured values to the Thinks Worx servers. On-line monitoring of the locomotion subsystem with prediction and prevention of a possible mechanical failure is secured by analyses of the data. The data is also used for visualisation directly on the operator station at a model of the robot in a 3D CAD system.
