I have been working on a couple different toy robot conversions but would also like to start on a household robot that will actually do some useful chores. I ran across an old plastic kitty igloo out in the garden shed. It is around 2 foot tall and around 18 inches in diameter. I'm considering using some electric scooter motors and 12 or 24 volt batts. Can anyone suggest some good motors for such an application? I'd guesstimate a payload of around 15 to 20 lbs. I'm thinking an onboard vaccumm cleaner. A NOAA weather alert radio. An arm that could lift around 5 lbs. With a reach capability of say 4 feet. ( ideally be capable of opening the fridge door and bring me a cold adult beverage! It would also be great if I could send it out to the mailbox to get my mail.Any suggestions for a strong arm? I' ll post a pic of the kitty igloo soon so you all can see what I'm working with.
Here are a couple of pics of the "Kitty Igloo"; which is destined to become "IGOR" faithful servant and companion! Me thinks his creation is realitively far in the future. Perhaps come spring. For now he is residing with RoBo Jeep out in the garage. The top lifts off of the base; making for easy access to all the goodies inside. The opening will have a panel that will stay connected to the base and (hopefully) will support the arm/gripper. I'm kinda hoping for a mild winter so I can work on him a bit.
cool
RobotZ12248: Here is something to check out. I am using these in a robot here at the musem. http://www.robotmarketplace.com/products/AME-218-1003.html They have both right and left hand versions in 12 and 24 V versions as well. I am using the 12V version and have them hooked up to a Basic Micro Robo Claw 2x30 Motor Controller, which is basically the same thing as the Sabretooth 2x25. Both are available through Robot marketplace.com
They work well together and I can drive it over Commercial Carpert with no problem, so running it over wood or tile floors would be a piece of cake.
The nice thing about using the gear motors is that they will operated at a slower speed and have more torque than the scooter motors have and you don't need to build some sort of speed reduction with sprockets, or pulleys.
You can also set the max speed you want to set the motor to run at in the movement control panel.

Wow, that sucker pulls 21 amps at a stall. I see it only pulls 1.4 amps with no load. I wonder what it actually pulls under real life load.
