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

Step 5: 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.

Step 6: Attach Phone Mount to Top Level

I used hot glue for this step.

The next step will show a picture of this.

Step 7: 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.

Step 8: Install PocketBot Telepresence Arduino Library

Step 9: Install PocketBot Onto Android Device
