In theory yes. Since the motor will be powered by the aux power supply only, as long as it is at 3 volt, it should be OK.

| | using 3v motors?
|
|
Is there any way to use 3 volt motors on the Handyboard? They draw about 400 ma. Using a series resistor of about 10 ohms works, but it will have to be about 5 watts, consuming a lot of power needlessly. The FAQ shows how to run 6-36v motors through (...)

Hi, Has anyone been able to run as11 on a Mac? As a first test of the assembler, I've been trying to re-assemble pcode.asm, without success. Specifically, as11 balks at the preprocessor directives. I tried running pcode.asm through the CodeWarrior (...) (24 years ago, 13-May-00, to lugnet.robotics.handyboard)

I see. Humm. May be I can really use this. OK, if I put a few IR LED with ID at different locations in the room, and put them at the same height as the robot sensor so I don't need to worry about tilt angle. If I put the sensor fixed on the robot, (...) (24 years ago, 12-May-00, to lugnet.robotics.handyboard)

Actually, I am going in that direction. I was trying to use the ultrasonic transducer to produce a signal and then use two detector to triangulate the location. That wasn't much of a success. I will need to redo the parts. I want to try using more (...) (24 years ago, 12-May-00, to lugnet.robotics.handyboard)

(...) No design, just an idea. The way I see it, you put a "Head" on the top of your robot. It has three sensors mounted for tilt and pan. The easiest way I can see it is to use gear head stepper motors with a "Home" switch to point the thing. The (...) (24 years ago, 11-May-00, to lugnet.robotics.handyboard)
