The use for driving robots is increasing in tests of electric construction machinery and automotive using chassis dynamometer that require long hours of operation in order for battery SOC tests. Existing driving robots are not very convenient, such as taking a lot of time to install. Therefore, in this study, basic research was conducted for the development of a driving robot that reduced the installation time and improved the followability of the reference speed profile by using deep learning. In order to follow the speed profile of the standard test cycle according to the regulations, a base study that can control the throttle by using the visual information in real time was conducted using a rig device and deep learning. Based on the results of this study, it is planned to conduct follow-up studies using test vehicle and chassis dynamometer in the next stage.

As the logistics industry continues to grow, the use of unmanned equipment such as unmanned pallet trucks is increasing. In this study, a path control study was conducted using a three-wheeled pallet truck rig with driving power of 1,500 W and steering power of 400 W using MPC (Model Prediction Control) algorithm for path control of a three wheel unmanned pallet truck. Through the analysis, the main control variables of the driving and steering motors were created based on the main path coordinates, and using this, it was confirmed that the driving of the element motion required in the pallet work was possible by following the main coordinates given through the driving experiment. In the future, based on this study, we plan to conduct research that adds dynamics modeling and further enhanced control.

In this paper, a method for implementing software for the control system with dual structure in processor module is proposed and implemented to enhance its reliability. In this implementation the multi-tasking function which is provided by a real-time operating system is applied. The overall software is divided into five tasks and is performed in each of the dual processor module, independently. By this, the processor module with dual structure can achieve a control objective and fault diagnostics effectively. An experimental result shows that the backup processor module can be substituted for the primary processor module immediately when it happens to fail, because data relating the failure information are exchanged continuously done via shared memories.
