What's this? How's it going to work? How will it be actuated?
Guess correctly and you get a cookie.

21Jake21im guessing its going to be used to pull your robot up the tower by folding it

Chris is meOn the right track...
Note: as pictured it's not robot ready, it's missing various pulleys and spacers and whatnot.
25-01-2010 17:51
Techgirl675or it could be used to right the robot if it turns over? I'm pretty sure it's to lift it though.

EricVanWykI think it is one of 8 legs for the robot. During normal configuration, it shuffle walks carefully with each leg bent up inside the BUMPER PERIMETER. During finale, it stretches the legs and gallops up the bump onto the tower. As an added bonus, the bot can now shoot in 8 directions.

rsiskI think it is a workbench or table, used to intervene between an object and the gravitational pull of the earth below it. This one seems to be decorated with some sort of robot device and a collection of sockets.

Jamie KalbThis is a three stage extending arm, right Chris? You're going to use it to lift some sort of hook up to the tower, then winch the rope in to lift the robot. The arm doesn't have to provide the lifting force, so it doesn't have to be very strong.
Did I get it?

Yup.
![]() A prototype is being built to actuate it from folded into the bumper area to fully extended with one pneumatic cylinder. Hook velcroed to the top for secure hold yet easy removal. |

Yay for winches, I believe we're doing something similar on our bot this year.

Nice! This was an idea my team discussed a lot. One piston is going to actuate that whole thing? How does that work? I like how it's a really simple system, though.

Something about the placement of the pivot point pulling the string and something like that.

martin417I would bet that the final design looks something like this (on a smaller scale of course):

LINK (if embedding doesn't work)
25-01-2010 21:33
Chris is mePretty much exactly that. When all's said and done it may only have 2 or 2.5 stages. Very light and simple is what was desired, and a folding option to keep the tunnel as a possibility and to lower CoG during normal operation.
...I guess I'm defeating the point of a teaser if I tell you guys what it is.

Akash RastogiWhat's your winch looking like so far Chris? Which motors and gearbox.

fordchrist675To me it reminds me of an arm scissor lift. so exactly like the trucks. I like the design really hope it works out. what are you planning on having actually latch onto the tower?
26-01-2010 16:06
M80I think that you arn't going to use that part at all and you'll pound it into forks to eat meat loaf with.

gyaniv... looks like what we are thinking about... would like to see it work
