Technically it would be possible indeed. But as TouchRemote is not designed for this kind of appliance it will not be handy to control your robot I guess.
Current options are:
1. If you show the camera output on the desktop of the laptop you can watch it on your phone.
2. If you can control your robot via keyboard or mouse input you can use TouchRemote to some extend.
However, tell me more about your robot project! How do you capture the video? How do you control the robot?
