766 Robot 2008

[Blue_Mist]

Drunken Squirrel (Nicole's)
Caffeinated Squirrel (mine)
The Guillotine (more appropriate as elevator name)
Walrusbot 2.0 (remember Walrusbot 1.0? From '06 Phlebus the Transformer/Whambulance/Informer)
Invisible Rogue (Referring to the hidden chain; will it be difficult to maintenance?)
And likely more to come!

Note: That yawning cavern in the background is our infamous Closet, with self-built welding screen and scrap box in sight. It is perpetually organized chaos, the inspiration for many a limerick, and the rookie initiation with cleaning, sorting, and introduction to safety (here are the safety glasses/this is the soldering iron- this is the hot end).

Nick we actually are 119.6 (dad weighed it right before ship) and we are missing some 1/4- 20 bolts for the bottom plate so we have no weight for decals . Hooray for speed holes in our armor!!!

119.6 !?

And we don't even have decals or all those bolts in. Besides, don't forget that the camera still isn't on the robot, and although I know it's not crucial it'd still be really nice to get it onboard. Not to mention beads for the elevator drum. We may have to do more than just cheesehole polycarb. That air cylinder on top has always been too heavy for my tastes...

That looks like a sweet bot. We have an elevator on ours as well, but we had trouble powering the cables (continuous like you guys). Could you go into more specifics on the design of the elevator, im very curious. Once again, solid design guys, thats fantastic work!

Thanks! I'm glad you like it. Unfortunately most of the elevator mechanisms are hidden in this picture, but you can see some of it near the bottom of the robot towards the front. There are two blue shiny things which are the AndyMark planetary gearboxes that we used to adapt the Fisher-Price motors to the AM Toughbox (about a 46:1 reduction in total). This gearbox chain-drives a polycarbonate tube (visible in the photo just beneath the gearbox) mounted between the towers which acts as the drum to wind cable. We positioned the drum with the axle running front-to-back so that as the drum spins, it pulls in cable from either side. These cables go out to the towers flanking the robot and loop through a total of 8 pulleys on the different stages to form the continuous lift.

that is pretty cool, it's looks like one of the designs we were contemplating using, until a different idea came up of course, lol, that's awesome .
