This is a 6 lbs idler on 115's 4 wheel drive system. It's going to do nothing for the robot at San Diego, other than supporting 2 idler sprockets at the bottom 3/8" shaft, allowing the drive train to transfer power from the toughbox to the idler and down to the wheels. Here at MVRT, we try to come up with the most complex solutions for simplest problems.
By the way, that 1/2" Craftsman ratchet is not left on there by accident. It's going to go on the robot too, just for fun.
Complex solutions for simple problems. That's our motto.
P.S. Our motto might change to "Simple solutions for complex problems" by SVR, at least, we hope so.

Was its original purpose to lift or to kick?
I'm assuming kicking, b/c the dog-gear could be used to vary the range.
GL in San Diego! NorCal FTW!

We too recognized that given the well-proven ultimate strength of a craftsman ratchet, and the robust design of the ratcheting mechanism, that it was a far better anti-backdrive mechanism than we could machine ourselves.
How are you retaining the end?

Ken,
You picking up a robot or a Jeep Wrangler?

.It's a gearbox design to take the power from one side of the drive train, and power the spool when the dog gear is engaged. When the dog gear is not engage, it just sits in idle mode doing nothing.
Unfortunately, we didn't have time to complete the hanging mechanism before ship, and we don't have time to complete it by San Diego. So the gearbox is just going to sit in idle mode through out SD.
We are hopping to get the rest of hanging mechanism figured out by Silicon Valley, though. The entire hanging mechanism should take no more than 8-9 lbs, including the gearbox shown above.

I like that, can't wait to see it in action.

You stole my team's winch 6 pound idler ideas 
. My team is using a CIM geared through an AM Planetary and Toughbox Nano, with AM Hubs serving as a makeshift winch weight addition. You even use the same inexpensive ratchet.
