Crab + turret + catapult + grabber. That's pretty much the most intimidating combination I can think of. Except for also putting the turret on a lift. But maybe they've done that too, and they just won't show us until competition. ;)

Okay, the crab and turret is freaking me out. You guys are gonna be amazing this year, consider me a fanboy. I'd like to seem some pics of the control board for that thing.

Re: Robonauts 118 - Unveiled '08
 

you have an amazing bot
good luck in competition
-post more pics

Re: Robonauts 118 - Unveiled '08
 

Hmmm is there a mode that auto controls the turret to stay in the same orientation relative to the field? Looks like it :)

could not say it any better

Re: Robonauts 118 - Unveiled '08
 

Wow, all powered by surgical tubing is it? Im assuming you made some sort of transmission on the winch to allow free spin when you release but how do you keep it from back driving the motor once its "charged"?

Re: Robonauts 118 - Unveiled '08
 

Hmmm, I doubt that the robonauts are going to rely solely on another robot knocking down the ball for them. I think 118 probably still has a few surprises in store for us.

Re: Robonauts 118 - Unveiled '08
 

That piston you can see in the transmission is pushing some sort of dog-like device into a disk/gear/etc to lock the transmission.

Re: Robonauts 118 - Unveiled '08
 

So then it has 3 gears? Drive, lock and free? How can you do that with 1 piston?

Re: Robonauts 118 - Unveiled '08
 

It may have two pistons in the transmission not just one.

Re: Robonauts 118 - Unveiled '08
 

From what I could see in the video it looked like there was one big (1.5") piston. I could be wrong...

Re: Robonauts 118 - Unveiled '08
 

great job

Re: Robonauts 118 - Unveiled '08
 

i think that they use that piston next to the motor there to disengage some gear or dog of some kind that allows thier winch shaft to spin free. then the dog reingages to allow them to winch down the catapult again. im not shure, i will have to ask at LSR

Re: Robonauts 118 - Unveiled '08
 

I agree, so then my question is, how do they "lock" the gears from moving, or do they hold it down by continuing to run the motor at a low speed. This would explain the fan on top to cool it down from all the heat generated by doing this. Am I right or do you think they are doing something else?

How long does the battery last on that thing, eh?
