pic: Finally, the Martians Are Up

[Alex Golec]

Ah, finally!

World famous Martian drive again? It would look so much clearer with a real picture

This creation looks somewhat light at the moment... are there some ramps missing perhaps? I would guess that the ramps, (if any), would be side-folded platforms with individual ramps, a la 33 & 47.

I look forward to seeing the real thing at Great Lakes!

Are those bumpers legal? I thought that you could not extend into the corners.

Hopefully that is just a stylized drawing. Only soft bumper parts can extend into the corners, not hard backing. You could have longer bits of noodles and cloth.

So what is this world famous dirve train anyways?

They have a 6 motor drive. 4 cims and 2 fp motors. So thats half the victors.

I wouldn't be surprised if the martian drive hasn't been upgraded. The "box" around it is sooooo enormous. Maybe even 8 on the drive. either way, it appears that 3 victors at least are for the arm, and 2 for brakes.

My thought:
6 drive motors
2 brakes
1 arm extender
1arm angle changer
1 arm turret
1 arm close

thats 12 folks.

Here's the totals:

4 small CIM drive motors
2 FP drive motors
1 Globe motor brake/ball caster actuator
1 Keyang for azimuth drive (turret)
1 large CIM for elevator (arm lift)
1 Globe for telescoping arm
1 Keyang for end effector wrist
1 Denso for end effector claw

total 12 Victors

possible late addition - Banebot motor with spike for ramp deployment

That's a lot of degrees of freedom on that arm. I certainly hope you guys have a good program and OI.

Ours is roughly equivalent (turret, extension, arm, wrist) and its actually not that bad even when completely under human control. (Mind you, ours is running at half speed) The key appears to all in how you think about it. If you think about it as a turreted, double jointed, telescoping arm, then its rather tough to control, but if you think of it as a single jointed arm which can be repositioned relative to the robot vertically and horizontally, and use the wrist for final scoring, it appears to help.

Just wait till ya get a chance to wire all 12 of those victors!
