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.

I am interested to see the Kitty Igloo!
I have a old Peg Perego 'powerwheels' Jeep in the garage that I am parting out. I did a little research and these motors and found out they are pretty beefy (170 watts). So at 12V that rates them at about 14Amps if I am doing the math correctly. I will probably need a 25A H bridge to handle them. I think the battery that goes with the Jeep will work fine if I want to do any other work like a robotic arm. Not sure what your budget is, but mine is pretty small....so building a strong arm on the cheap will be a great challenge and I will certainly be interested in your progress if you are looking to save some $$ as well with your project!
I am liking the retrieval of adult beverages from the fridge concept alot!

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.
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.
