3d printed enclosure with stepper motor and arm, for pressing a button

compensation: Up to 2 days of work expected

QR Code Link to This Post

I am looking for a local hardware engineer to build a way to mechanically press (and hold) the button on the front of a Bluebot Mini (https://www.bluebot.com/shop/bluebot-mini/), in a repeatable and reliable manner, using a stepper motor and a 3d-printed attachment. It cannot damage the Mini in any way when attached, and it needs to work when the Mini is attached to a pipe. I need to be able to move the enclosure from one Mini to another if necessary (not often).

I will provide:
- Bluebot Mini attached to a copper pipe
- 28BYJ‑48 stepper motor with ULN2003A driver board

I need someone to design and print an enclosure that attaches securely to the Mini, and has the motor secured(via screws probably, here is a good file to use https://www.thingiverse.com/thing:423357/files), and also design/print an "arm" (like the attached image) that will attach to the 5mm flat motor shaft and press/release the button when the shaft rotates forwards/backwards.

The QR Code on the mini should not be blocked either (it needs to be scannable by a phone camera).

I do not need any code written, but you need to be able to demonstrate the motor pressing the button (using whatever development board or approach you want to take).

If interested, please send a price quote and timeframe to start/complete the job. If you have any related projects you've done before, that would be helpful to see!
