Your pickup and gripper may have been one of the coolest things I have ever seen operate on a FIRST robot.

Re: Most Unique Features

Anyone else have a pair of Reeboks on their robot?

I'm not talking sneakers, 2 RBK 6k stiff flex hockey sticks. Nice & light and made to take a beating.

Re: Most Unique Features

Our robot is pink...PINK!!
haha

besides that I like our drive system...mainly because I suggested it. It encompasses only one drive wheel on each side, both in the middle. Then four caster on the corners. It can spin 360, which is cool. Nothing compared to meccanum, but it's still pretty cool.

And here I thought you guys got a Reebok sponsorhip....:rolleyes:

Re: Most Unique Features

does having Jesus on your controls count as a unique feature?

Re: Most Unique Features

We can retract our ramps if something goes wrong. We've got a Banebots on each, extremely geared down. (Arguably the biggest sprockets I've seen for #25 chain in FIRST on the ramp end, and a small set on the motor end.) Also, our hidden pneumatic gripper actuator. It's buried in a fiberglass tube.

Well if we ever get hooked up in an allince together we can be the "most offensive" alliance.:D

Re: Most Unique Features

For us, I would have to say our gearboxes. Heres another thread on it http://www.chiefdelphi.com/forums/sh...ad.php?t=54420

In more ways than one ;)

Re: Most Unique Features

I think that a unique feature of G.R.R.'s robot is our arm lifting mechanism, two sets of drawer sliders rigged up as a block and tackle pulley.

Re: Most Unique Features

We have an extendable ladder, that you can climb 8 feet up on. Unfortunately, it's not quite stable enough to actually climb.
I don't have any pictures right now.

Re: Most Unique Features

This is our robot. (unpainted)
It's unique features:

1. Through a strange system of pullys, the arm can extend to the top row.

2. A ramp is built into the chassis. The ramp is made of 2 triangles forming a rectangle that unfold to form a ramp.

3. The ramp is deployed using the arm. Through extending, the arm can push the ramp away from the rest of the chassis and into position.

4. The ramp, once in position, can be lifted paralell to the feild and lift 2 robots 14 inches.

5. To increse the width of the ramp, the ramp's plates are hooked to a system of bungee cords that, when the ramp is lifted, pull the plates outwards and greatly increse the ramp's width.

:D :D HOPE YOU LIKE IT!:D :cool:

Re: Most Unique Features

Oh and i forgot to say our robot has a digital compass so it knows were its facing relative to north so we can use drivercentric control. Its pretty sweet we can make the robot auto correct itself to face forwards again or because of our mecanum wheels it can go to my forwards no matter what way it faces.

Re: Most Unique Features

116 has a slew of unique features on our '07 bot.

I'll start with our control systems. We have the latest iteration of our "control box" design, which serves several purposes, including protecting our control components, cooling the components, and allowing easy access to them between matches (see 2005 thread).

You may notice that on top of the RC is a circuit panel with an LCD. It is mounted in a clear polycarb case, with a "D-Pad" and selection button, and allows for us to change autonomous plays, and check basic diagnostics on the fly. We are working on getting the kinks out of the ability to actually write new autonomous plays from the LCD as well.
Our arm is simple compared to many that we have competed against. It has a shoulder joint powered by two globe motors, and pneumatic actuated wrist and claw (both rotate on the same axle). The arm is comprised of two pieces of aluminum box channel, one segment is 1.5"x1.5" and another is 1"x1". The 1x1 can fit withing the 1.5x1.5 at the start of the match, allowing for the length of the arm to fit in the starting size requirements. A piece of surgical tubing is attached to an eye bolt which is attached to the inner tubing (and fits through a channel milled in the outer tubing) at one end, and the outer tubing at the other. The eye bolt fits behind a bar in our shoulder joint at the beginning of the match, holding it in the retracted position. When the arm is raised, the surgical tubing pulls the inner channel outwards, extending the arm (where it can score on all 3 levels and pick up off the floor). The eye-bolt then locks in the extended position.
