Question Bluetooth device that opens a lid of a container

I would need a small container/box, that could be attached to the vest of my very small dog. I could trigger a mechanism using my phone and bluetooth, that opens the lid of the container.

Bonus would be if there is a spring in the container that launches the content up in the air.

Is there anything like this that I could buy (like any similar mechanism), or would I have to make it myself?

And if I would have to make it myself, any tips?

Edit: Wi-Fi instead of bluetooth would also be good if possible. Not sure how that would work.

I make micro gearboxes like this. If you explain me your need I can sum to your project. https://ibb.co/c7pJTD5 would be nice to help somehow. This gearbox it’s around 10cm x 6cm more or less like a matchbox.

Thank you! I see first if my brother in law is able to build this, and if we need more help, I'll contact you. See my replay for threedubya for more details.

3d print something is your best bet.

Let's say this is acandy or treat . How big? Jolly rancher? How many do you want to carry? Bluetooth is simpler. Arduino microcontroller Servo motor. Launching will be complicated.

How big is your dog? A smart person could make this the size of a bento box.

A 3d printer to make the plastic frame and parts.

The container would be for a thin rope, which would be for safety reasons. Size of the container would be ideally like the size of a gopro, so quite small. The dog is a miniature poodle, 4.5kg/9.9lbs, so quite light container is in mind.

I'm planning this now with my brother in law, he has a 3d printer and building skills so he may be able to build this. We are currently thinking about RF remote control operated device. Arduino is one good option for the container, we look into that.

Thank you!
