I need to get a lot of power with little experience
« on: July 30, 2007, 09:51:54 AM »
i'm building a robot that's gonna follow me around and carry mi stuff while i walk to school. i'm gonna need a lot of power and i don think 9V batties are gonna cut it. I need mi robot to power washing machine motors and the load will weigh over 30 lbs. I also need to no wat to use to enable the robot (with the $50 robot microcontroller) to be able to control that voltage....could i use a transistor or a relay?

You will need to use a pretty heavy duty AC Motor Controller... Here is a link that will get you started... http://motion-controls.globalspec.com/LearnMore/Motion_Controls/Controls_Drives/AC_Motor_Drives

You might want to consider different motors, as washing machine motors are AC, not DC.

Consider buying a used electric wheel chair (EBay?) and hacking in your microcontroller to operate the already built in motor drivers.

If I were to do your project, this is the approach I would take.

How will it know who you are so that it can follow you?

Ummmmm that wont work I promise you.

You most definitely would need a camera, with you wearing bright clothes . . .
