I believe I have created a robot that's functional, helpful, entertaining, whimsical AND simply amazing.
The ServerBot. Built upon an iRobot Create
A robot with the ability to move reliably between any room in the house while carrying a payload, in our case, a serving tray on top. The ServerBot has a much greater potential with other tasks of moving laundry and such. The elderly could appreciate a ServerBot to help transport just about anything around the house.
You are in the Kitchen with a tray of popcorn and drinks for movie night. You have more to take out but can't carry everything in one load (or you are physically disabled and are unable to carry everything). Just push the ServerBot CALL button and within a minute or two ServerBot arrives to assist you. Place your items on top and press the button on the ServerBot for the room you want it to deliver its payload to. Off it goes.
It knows its way around, carrys things for you, talks to you, and won't bump into things.
This is a Live Working Model that we are actively using at my house. My goal with the Create has always been to make something USEFUL out of it. So far this is IT. This project will continue to evolve. We have plans for interchangable bodies, one of which will be a big Ice-Bucket so it can roam around with cold drinks at a party. As-is, it can roam around at a party to deliver drinks and horsdevours and return to the kitchen for re-stocking.
The ServerBot can be covered and re-covered in different fabrics to match your decor or a party theme. This covering is held on with scotch-tape, I'd suggest something less tacky. Ha!
The current ServerBot has evolved over a period of time so I don't have good pictures of it's construction. I am now documenting the building of the next one in more detail so keep watching.
This bot is not as complicated as it may look with all the following technical mumbo-jumbo. If you can solder, then you can build the circuits without any trouble. You don't have to use the same body I did, anything will work (a cardboard box would do just fine). Very few parts are required and all parts are readily available online or at your hardware store.
