Wheels for Life-Size Doll

Hello,

I’m an artist usually based in London but currently in Perth, Australia visiting family over the summer holidays. I’m preparing a life-sized version of myself to be part of an exhibition in Queensland in late January 2020, so will be based in Australia for any products that may need ordering or searching for.

I am looking for some information on weight bearing programmable wheels for using on a life sized humanoid figure. Previously I have used two remote control cars as my robot’s ‘feet,’ but I was conscious that the cars weren’t able to function very long because they weren’t designed to hold the weight of the figure. The figure weighs approximately 20kg.

I would like to either construct or purchase a pre-constructed product (one for each ‘foot’) that would be able to function as the robot’s feet. Ideally these wheeled feet would be programmable so that the robot could move without remote control. I am very basically familiar with Raspberry Pi and have used programming with it to make remote controllable shoes previously, but the components I used with them wouldn’t be able to hold the weight of the life-sized figure.

Images of previous version of robot doll:

Any insight or advice you could give me would be very much appreciated.

Here are some links to the videos of the works I reference above.

Thank you for whatever insight you can offer!

Hello @rebe_kah and welcome to the community!

Cool project! I think this tool can help you out with the motor requirements for your project:

You just need to fill the input boxes and then you can choose a motor according to the output specs.
An easy way to go trough the motor selection here is using the comparison list:

Or if you want a pre-built product you can check for a wheeled robot that meets the project requirements.

Good luck!
