This week we have worked with much of the same as last week. 

The new thing is that the motor which will control the pump is working, but we have to make a new 3D model of the pump before we can test the it.

The trolley, which is mounted on the rod, was a bit tight. So we made a new 3D model with some adjustments on the position of the wheels, and we also added a trace (sling) which will lock the belt that pulls the trolley.

The motor that pulls the trolley is working, but the rangefinder is not. We first tried a infrared sensor, but it was’nt exact enough, or very polite. Since we dont have a lidar, we will try two ultrasonic sensors, one on each side.
