Week 3 progress

This week we changed our way of realizing the project. The idea used in week 2 was that we tried to install the ROS program (robot control program) in Arduino Yun and access the Yun board via SSH terminal. But this is not in agreement with the supervisior. The supervisior suggested that the team should still control the robot via the cyton viewer software. The graphical interface should not be abandoned and our method sacrifised the graphical interface.
With the help of the lab researcher, we modified the project and now the process changed.

In this method, the first step is to connect two PCs. One is the server and the another one is the client. The connected two PCs could connect each other, send and receive data. They are connected either using ttyd, telnet or remserial method.
The second step is to connect the PC and the Arduino Yun. They are connected using the same method: either ttyd or telnet. Yun could receive data and send back to the server PC.
The third step is based on the second step, Yun is connected to the robot arm and realize the wifi control of the robot.
