Playing with robots in London
Last weekend Middlesex Universtiy took part in London Design Week with a pop-up installation entitled "Robot Overloards"
The basic premis was as follows:
- Children dress-up as robots
- They stand on a pressure mat
- The robots decide if the person on the mat is a "ROBOT" or a "HUMAN"
- The robots either "work" if they feel the person on the mat is a robot (and thus might replace them) or "relax" if they feel the person on the mat is a human (and thus poses no threat)
To achieve this, we used a pressure-mat connected to a PI, which broadcasted a "pressed/released" topic, and subscribed to these via baxter.

The joint_position_file_playback.py script, doesnt allow for multiple playback of different files.
I split this into two seperate scripts,
