**7. Conclusions**

In this chapter, we focus on QoS control for remote robot operation. We introduce our remote robot system with force feedback which we constructed to study QoS control. We also present the expected applications and the problems to be solved for widespread application of remote robot system with force feedback. We mainly focused on the problems of network delay, delay jitter, and packet loss. We explain several types of QoS control which we previously proposed to solve the problems. Finally, we also discuss the challenges and future directions of QoS control.

For the future plan of our study, we need to solve the problems described in Section 6.
