 Teams that are consistently designing and end up with weight problems need to look at their design process and make corrections in "Weight Management". - Mike Martus [more] |

We also have two speed andymark transmittion and a 842 style kicker ( can't really see in this picture). Any input/ comments?
p.s. 10 points to anyone who spots the easter egg.

Are you lifting yourself with a winch? or is all your lifting going to be done with the telescoping arm?
Very sweet idea using the pivoting rods for the wheels, have you tried this on a mock bump yet? that would be cool to see.

Looks good. Have you guys tackled a bump yet? If so how did it fair? Also the arm looks nice. I sure do wish we had somebody that could get us some of that nifty bosch rexroth extruded aluminum to work with.

I was wonder how long it would take for someone to notice

Good luck!

My only question is this. How well does the arm hold on to the tower? I really enjoy the 8 wheel pivot design looks great.

We took the arm off for testing. We filled up two tote boxes full of gears, motors, and batteries (roughly 250 lb) and it lifted them in 10 sec using the old van door motor. So there is definatly room for improvment. It climbs the bump like a dream.
As for the spinners...come on, do you really think we would show up with out our bling?

We're going to find out soon enough for ourselves. Have you used other robots to push against your robot to see how your drive modules react to external forces without a suspension?

It reminds me of monster truck rallies, with bling!

I understand that this is basically your 2005 robot and that you are taking into consideration and improving the concepts from that bot. . .
But even though the robot will be able to travel easily over the bump and somehow hang in during the last 20 seconds; the 8 wheel drive system worries me.
. . . How well does it turn?
. . . Is it fast enough to play defensively?
. . . Kicking system? (If the robot is not that maneuverable it will have trouble lining up shots.)

After some testing, I think we are going to "bump up" to the 6 inch wheels and omniwheels in the front and back. This should solve most turning problems that might arise. I wont' lie, we have had some problems with turning in the past, but we should have that worked out this year. We are running AM 2 speed transmissions and 4 cims, so it is plenty fast enough, but who said we are playing defense?
