First i finished my circuit, its not difficult at all and it should look something like this
Step 1: Step 2- Cutting
Then I cut out 2 corners of a box that I found fit best around my boebot
Step 2: Step 3- Taping
Then I taped the two pieces together and that made the base for the bumpers to go on.
Step 3: Step 4- Gluing
Then I Superglued the base of the bumpers onto the boebot
Step 4: Step 5- Bumpers
Then I made the actual bumpers, they're made out of two pieces of cardboard and some tinfoil for the conductors
Step 5: Done!
This is what you should end up with.
