Let's Make Robots!

Crazy (or not) idea: Butler Bot

NOW THAT I HAVE PICTURES, I'VE DECIDED TO MAKE THIS INTO A ROBOT PROJECT - http://letsmakerobots.com/node/31415 THIS BLOG WILL NO LONGER BE UPDATED

 

So today I started drawing up plans for a very simplistic "butler" type robot. It would have a base with 4 continuous rotation servos, and an omni wheel attached to each, making it very mobile. On the base would be a wooden support with a tray on top for putting food and stuff. It would be controlled via IR, and I could possibly add some sensors later. Let's say you're in the kitchen preparing drinks, you could put them on the tray when you're done and then use the remote to guide it to the table and let the happy drinkees unload it. It was inspired partially by Fritsl's Partybot, which you can find here: http://letsmakerobots.com/node/23453

Anyways, I was worried that the tall support and wooden tray would be  too much for some cheap continuous rotation servos, and I didn't have parts to make a base. However, I do have access to all my dad's scrap wood. So I decided to make some use out of my MAEP (go check it out if you haven't: http://letsmakerobots.com/node/30979). I've started working on the butler tray, I've found the perfect pieces to use. I'm pretty anxious to get working on it right now, so I'm gonna leave. Keep an eye out though, I'll have more updates coming soon (and maybe some pictures!).

UPDATE:

Now with video! I don't have too much to say, just watch the vid ;)

It actually works pretty well for a prototype. I think that everyone should have either a robotic butler or a robotic maid in their homes just to help out with pretty much everything.

Thanks! I made a robot post for this project now, have you seen it yet? The new base is much wider, so it'll be less prone to tipping than this prototype.

Good start. You should definitely do a ramp-up/ramp-down on the motor speed, to avoid drink spashes or tip-overs.

Thanks, I fooled around with the code a bit this afternoon. However, I couldn't get to a point where I had good ramping and good responsivness in terms. However, I have already built my second version of the chassis, with a much wider base. I think that'll be a big improvement.
