pretty good robot. Im from team 254A, and you guys bet us in the skills challenge by two points. What can i say, this robot can score in the green ball goals our can't, good robot
After it expands it is definitely over size. It becomes 28" long by 24" wide by 17 1/2" Height. The bottom of the scoop is 20" by 14" after it folds out and locks into place. To start the match, before expanding, it is 17"L X17"W X 17 1/2"H.
i know how ur robot works but there are some things that i dont understand care to explain?
is the scoop [ as in the front part ] up before starting the match but how does it stay at the position?? and when it is down why it wont move back to the original place
why did the omin wheel at the front move out and how does it stay at the position
The scoop is held up by the wheels that are folded in to start. The floor of the scoop stays straight after it opens due to a rubber banded lock that snaps into place upon opening. The front omni wheels pivot out just by powering the front motors during autonomous. The wheels drive themselves into position. There is a pin on each side that fall into place to lock the front wheels outside the frame.
First i must say. Simply Incredible! You dominated out team in Elevation, and now this!
I am just awed at how the things click into position but i cant get my head around how they click in and how the pin drops, could you possible explain how you got it to lock in? My hopes for round up are currently down the drains, but hope to see you there!
Thanks. If you go to the team's most recent Youtube video entitled, "Green Egg Robotics, Fred III Clean Sweep Highlights" you can see a closer view at 1:42-1:55 of the robot and mechanism in slow motion as it opens.
The pin was an axle with a collar on it (to keep it from dropping through completely). The pin was resting on a quartered green gear at the start of the match. When the wheels rotated out, the pin slipped over the edge of the gear and locked the wheels into place.
I am told it was 5:1 using the high strength chain and sprockets on both sides of the scoop. Also they used quite a few rubber bands over makeshift pulleys to assist in lifting.
I think you're asking about when they are scoring on the triangular goals(?) To allow it to close in, they connected the back of the scoop to the floor of the scoop on a pivot point. They then used rubber bands attached to both sides to keep the back from collapsing. When they go to score on the triangular goal the back closes in as it pivots on the "hinge". When they move off of the goal the rubber bands pull it open again. I hope that answers your question. Thanks for asking.
There is not much weight on the front wheels (powered by 2 motors). That allows them to move at the same speed as the back 2 wheels (powered by 4 motors) which have most of the weight of the robot on them. That is what James from the team tells me...
How does Fred III move straight sideways with a 6 motor drive? I figure that the more powerful back wheels would cause it to move slightly forwards, but it doesn't.
who got the pts for the last white 1?

I don't believe anyone got points for the one on the wall between the 2 robots. I think both robots were touching the ball negating the points.
