Simple Bots: Scrub

Step 3 Attach the track

Place 1-1/2" bolts down through the adjustable track such that the middle slider part is facing upwards.

Insert one or two nuts to space the track off of the scrubber brush in such a way that the middle slider can move freely.

Insert the bolts into the hole on the scrubber brush and fasten it on with another nut.

what do the tracks help with exactly? i have a school tech fair and i would love to make one of these

Positioning the brushes changes its footprint (how it comes into contact with the floor) and by extension, the patterns in which it moves. The frisbee is not perfectly flat, so moving the brushes is actually slightly changing the way it contacts the floor. If you leave them mildly loose on the track to reposition itself, you will start seeing different behaviors emerge.

ok thanks

would it work the same if you just glued the brushes to the frisbee?
