Hello, New member here and first posting. It may be a stretch to call this a robotics project but here goes. It's a working transformer costume, similar to this:
http://digg.com/video/this-street-performer-has-a-working-transformers-costumeI need help sizing the motor.
Wheel diameter is expected to be 10" so I estimate 50 to 90 rpm to achieve walking speed. Total weight with costume between 170 and 190 lb.
I'm looking to direct drive a single front wheel with a battery powered DC motor to accelerate from stopped position to walking speed on level asphalt. How much torque would I need? Can anyone recommend a vendor or even a specific motor?
