Assemble the robot frame

Pretty straight forward. Adafruit has directions if you need them.


Mount the Arduino

Use the included hardware to mount the Arduino. Anyway you can get it to fit should be fine.


Remove Suction Cup

The lever that holds the cup in place can be pried loose with some force. It has a pin that slides out. You may break it while removing but that’s OK. You can just throw that part away along with the suction cup and spring.


Attach phone mount to top level

I used hot glue for this step.

Attach battery pack to front

I also used hot glue for this step. The batteries are very difficult to change. So I think this part should be improved. However the weight of the batteries help counter balance the weight of the phone. This end of the phone could use a little more weight.
