**3. Expected applications**

As shown in **Figure 2**, the remote robot system with force feedback is expected to be used in various areas.

#### **3.1 Remote surgery/rehabilitation**

In order to solve the problems of imbalance of medical resources, remote surgery/rehabilitation using the remote robot system with force feedback is an effective method. Also, the system can be used for remote surgery training for medical interns.

**Figure 2.** *Expected applications.*

#### **3.2 Work in dangerous areas**

It is difficult for human to work in danger areas such as deep sea and outer space. Therefore, we can employ robots to work in the danger areas instead of humans. By using the remote robot system with force feedback, we can control the robot which works in danger areas from a remote safe area. We can improve the efficiency and accuracy of work by force feedback.

#### **3.3 Disaster rescue and relief**

The remote robot system with force feedback can also be used for rescue and relief from disasters such as earthquake and concentrated downpour. In this case, the remote robot can be rescue robot or drone, and the system can be used to help people, to distribute goods for disaster victims. Also, it can be used to confirm disaster situation.

In these applications, it is difficult for only robots to work because the situations are unknown in advance. Thus, human's support is needed. This means that we need robots to help humans and robots also need human's supports. Therefore, the cooperation among humans and robots is needed.
