Here is a second, better lighted (albeit less clear) image fo team 25’s robot. As you can see- we are shooting for the wall and get there in 3-4 seconds.
We will be competing at Annapolis in 2 days and then at NJ and Texas.
I would be interested in your comments, opinions and or suggestions about the design and weakness you notice on the machine. That whole superstructure is retractile and the robot has 6 wheel, 4 motor drive geared 4/1. It runs at about 13 fps. Very fast and powerful.
It looks like you have what it takes to be one of the top teams at annopolis.
I would just look of for a tipping effect on your bot if another robot got to the hill as soon as you did. With you arm, it might make it a bit top heavy.
GGoldman: If our robot tips, the mechinism that raises up and down, can correct us.
David Lantz: those arms are made of aircraft aluminum, plenty strong, also, thye are powered be pnematic piston, they were specificly made to knock the wall down not to hit robots after 60lbs of pressure, they fold back up
K. Skontrianos: They wingspan is 110inches thats alittle more than 9 feet
Oh and for those of you who would think that our light is illeagal, its not, we followed the rules
You may have the arms nailed down, and what seems to be an impressive 6 wheel driving system, but can you put the money where your mouth is, and when push comes to shove, can you push back, or will you just have to self right??? Everything looks impressive though, and using the pnumatics, you should have plenty of pushing power.

I am with team 53, and our pit was next to team 25. Yes they did work on their robot while in the pits, but they did not replace an arm, not even scratch it. This 6 wheel robot was very fast, i think it was the nicest robot there. It looked cool. This bot has more power than most on stage, it defened their stack. Pushed all robots away, even on the ramp. Anyone can have a good bot, but I say that the driver/operator of team 25 knew what he was doing very well. He Controlled this thing like a dream. This thing is a tank…
“that which doesn’t kill us makes us stronger. NOTHING comes easy for team 25”
In the semis we were defeated by the eventual winners in a 1/1 decision. We had a failure in round one that was remedied in round two and a little bad luck(a wheel touching and 2 boxes short). No problem. The competition was great and the winners deserved their win.
But we fixed our machine now. And we are ready…
SEE YOU ALL AT RUTGERS AND HOUSTON
thanks for the props Serg. We’re just in this for the fun and friends.
as replic said many matches we ran 50%, apperently switching our gearbox from plastic to steel gears was really a bad idea, we had sooo much torque we kept destroying the transmissions on the drills, they really need to come up with better motor mounts next year
The torque situation is fixed though, thankfully. It was a nightmare replacing the motors in our highschool, but moreso in Annapolis because we didn’t have the luxury of time as we did before shipping.
The problem with our drive train was that the drills were mounted to absorb any forces from stopping too quickly with the drill brakes engaged. This turned into a problem when the mount was actually twisting the motors out of position, and dismounting the transmission. That is why we ended three matches with our drill tranys laying dead on the field. We fixed this, in quite a hurry I might add, by making the mounts rigid, now it works like a dream, and faster too!!!
It was a little hard to see it through the boxes, but we had a little too much speed. The bot actually got some air off of the ramp during autonomous mode and flew through the boxes!
And if anyone was wondering why our bot was cutting out during elimination rounds, it was because we had all four drive motors and the compressor running (voltage at sometimes was down to 6v). Anyone have the stats on how many amps the compressor draws so we can fix this problem?

We ran into this problem last year at VCU, before we tuned down our drive train. We were going fast enough to reach the goals in 1.8 seconds, but in those 1.8 seconds, we were destabalizing batteries.we tried to solve this by manually turning the compressor on and off using a switch on the conroll box, andturning off all things but the drive motors, but we couldn’t get it to draw much less current. So in the end, we ended up just slowing down our drive.
