pic: Finally, the Martians Are Up

[Rich Ross]

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.

[Jay TenBrink]

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!
