 yarpview /USERNAME/view
 yarp connect /fakebot/camera /USERNAME/view
  • The view is from a fake pan/tilt head. You can move the camera by sending messages to "/fakebot/motor/rpc:i". Try:
 yarp rpc /fakebot/motor/rpc:i

and type:

to see what you can do. Useful commands are:

 set pos 0 100

where the first number can be 0 or 1 (for x and y position), and the second number is the actual position. Similarly:

 set vmo 0 10

controls movement, but this time velocity. Be ready with:

 set vmo 0 0

before your robot head zooms off into space!

Remember other people in the class may be controlling the fakebot at the same time, so don't be surprised if it moves without you saying.

  • Read the encoder feedback (the position of the head). This information is available from the port "/fakebot/motor/state:o"

Try this:

  yarp read /USERNAME/reader /fakebot/motor/state:o
