Update implementation

I edited the part where the robot considered a full suction. It was the average pressure readings of the 4 chambers.

           prresure reading for all 4 chambers all drop and get really close to
           each other. So in the code, we compare the current pressure readings
           for all 4 chambers with a certain threshold that we got from trials

           successful, we compute a directional vector base on the difference
           between the pressure reading in different chambers, and normalize it
