• The arm can extend to 9 1/2 feet.
• The arm can swing over 180 degrees
• Six wheel drive, two CIMS per side, and one chain tensioned with idlers.
• The robot can load from the ground, the wall, and human player.
• Disregard the clamps, they were a temporary fix for filming.

See you all at the competition and please check out our new robotics TV show at youtube.com/mortorqtv

My concern about only having one chain driving one side of the robot is that if that one chain breaks you're driving circles the rest of the match.

[ZachKahn]

I agree but, we plan to keep a constant check on our chains' tension with two adjustable idlers per side. The idlers can be moved on a channeled slot to increase or decrease tension on the chain. All of our chain is going to be protected by the black plastic you see in the video. Hopefully this will prevent our chain from breaking.

my only concern is spearing the tubes. Watch out for that. I was at the FIRST Aid Station/Inspection area at scrimmage, and the arm looked pretty solid except for that one concern. Good luck.

Yeah, hopefully that will not be an issue. We've been sanding down the "tusks" on our arm to prevent punctures. We're also going to cover the holes on the outer segment of the arm with lexan to make sure no one gets their fingers sliced off.

good job except that i don't think you will have too much luck getting ringers off the floor? right?

also those hooks look kind of pointy

[Alex Cormier]

looks good, get your inspiration from 233 '05? Also is it able to pick up form the floor and where you guys going this year?

We saw 233 compete in Denver in 2005. We thought 118 and 233 were amazing. We adopted some of their ideas but had to work within our building constraints. We do not have the machining capabilities to do some of the other cool things that they did.

Yeah, the bot can pick up from the ground but we tested that function after we filmed the video.

We're going to Los Angeles, Denver, and Nationals.

We sanded down the points and tried picking up tubes off the ground. We lowered the arm into the middle of the tube while the robot was driving forward. Once the points are under the farther edge, we can pivot the arm up and pick up the ringer.

I dont know if im goin a little nuts but, i think i remember reading a rule that the only thing that you could to to the spider leg while scoring is push from the front, the side , and from the bottom, i dont remember anything about pulling the spider leg. and from what i saw, the students arm was pretty much pulled out when you guys scored.

I reread the rules after you posted your comment. I could not find anything against pulling on a spider leg. If you find something in the rules, please let me know.

Don't bother with full-weight lexan. Go with something lighter, like the cloth used to make the bumpers. You don't need to hold any weight with it, so it should be fine.

Good idea. We have some extra canvas laying around. We were also thinking about cellophane plastic wrap.

Yea, about that rule, its in the consolidated Q & A , its on page 6 under the name "Robot Part on the Spider Foot:

6.2 Playing Field

Robot part on the Spider Foot

Can a robot part lie on top of or touch the Spider Foot/Stinger, but not be held? There is no mention of the foot or the top of the leg in the below answer.

The Spider Legs are considered part of the field structure, and are covered under Rule <G33>. The Spider Legs may be pushed to one side, from the front, or from the bottom, to stabilize them during the process of hanging a game piece. However, they may not be grasped, held, or
severely restrained without violating this rule.

The Spider Foot and Stinger are considered sub-parts of the Spider Leg. As such, all rules and rulings regarding the Spider Leg also apply to the Spider Foot and Stinger.
