/diy/ - Do It Yourself

Anyone built a useful robot?

I want something similar to the Star Wards astro-mech/ utility droids.

I was thinking a full blown R2 type contraption that would follow me around and perform useful tasks.

When I say "useful" I intend to:

* Install a large deep cell battery in the lower chassis to use as a power supply. (12v, usb, variable power supply sockets and such)

* Perhaps a range of sensors to obtain weather information and maybe some other sci-fi-esk wank I'll personally have no use for like a Geiger counter.

* Stick my phone in there and just have a Bluetooth headset. Have the droid follow within range of Bluetooth or WLAN and just accept calls.

* storage - Compartments for things like: 12v soldering iron, tools, safe etc

* Perhaps a cattle prod (I don't wont children, niggers or other degenerate filth to touch it with their pathogen infested hands)

* 3g connectivity, GPS.

* Not really mandatory but perhaps some kind of waterproofing for rain.

How hard would it be to build one around a Pi and (god forbid it) an arduino?

And what am I looking at in terms of funds?

What I'm really looking for is possibly some links and personal experience.

tl;dr I want a star wars droid that's USEFUL.

And yes I have looked up various other projects on google.
