The Big Wheel has It’s Legs


It’s been a busy two weeks.  One of things that I’ve been doing is building the biped test stand.  The test stand is motorized.  I had a problem with an eBay motor order so had to order again.  I ordered from both McMaster and from ChancsMotor (eBay).  Both motors have arrived.  I’ve powered the test stand with the Dynatech motor from McMaster.  The ChansMotor just arrived this afternoon and I must admit that I like it a lot.

So the test stand is completed and operates under power.  This enabled me to move forward with the table for Big Wheel Lift #1.  I now know what the biped power module geometry is.  In the image to the right you can see the table, legs, and the mechanical frame.  I’m in the process of building the levers and cams and sprockets and etc.  I suspect that Big Wheel Lift #1 will be operating under power within the next two weeks.

A test period will follow, with the Big Wheel operating for about 3,000 cycles as it is fine tuned.  Then disassembly and paint.  Then reassembly and test.
