2.1.4 Charging system design concept of TUL modular platform The autonomous mobile platform project addresses also two fundamental approaches to the autonomous charging. The first approach is based on the use of an industrial robot with six degrees of freedom handling the generic charging connector of the Combined Charging System standard (CCS) (shown in the Figure 5). The system design is equipped with a dedicated effector, sensors to achieve optimal trajectory of its own mechanism, particularly industrial 6 DOF force-torque sensor and 3D camera vision system IntelRealSense where the control system running in Matlab software. Furthermore, more robust algorithms for precise guidance and insertion of the connector are dealt with even in low light ambient conditions. The final experimental system should form a compact unit allowing its installation in the field.

The second approach assumes design and testing of a proprietary charging system using a simpler, three-axis, NC positioning mechanism which utilizes a special vehicle socket. This approach has the advantage of easier connecting the coolant circuit of the vehicle with the charging station. The design of the power electronic of the charging system and the proprietary charging connector allows testing of a charging power exceeding 350 kW or 1200 A. 3. Conclusion Our survey of current research and development in the area concepts of specialized vehicles for the transport of freight and equipment showed a great potential for the use of autonomous specialized vehicles. Many promising approaches to the design of these vehicles are now in concept stage and therefore there is now a lot of room for research and development in particular areas of this field. Smaller robotic vehicles are currently
