Because of the location of the intake I keep seeing this as Mittens pre-launching itself to go over the defense, ie travelling right to left.

It is actually traveling left to right. The arm raises straight up and catapults in the direction of travel. ie: the intake is in the back of the robot, but it shoots forwards.

When crossing the ramparts we only take up half of it, making for a nice jump.

Oh I know. But my mind wants me to believe the opposite.

16 Is there too.


1296. Looks VERY familiar.

Pretty sure 3310 is there too

You aren't alone! 16, 1625, and 3310 are also running 775pro drivetrains.

If I may ask, what prompted a switch away from the 775Pro drivetrain? I have been curious as to their performance, seeing a few robots with them on CD, ans would love to hear more about what you liked and didn't like about them.

I'm sure they liked the size and power output but disliked when they were on fire.

We loved the 775Pro drivetrain! Each side with 2 775s, plate and reinforced VP weighed about the same as a single CIM. But we got something a little bit wrong (single speed, geared a little too high maybe? too much torque required to turn though it was blazing fast? needed better inter-match cooling?) and burned the motors up during semis at 2 different regionals after placing 2nd and 4th in quals.

We think we could figure it out and be OK. But bottom line, we don't want anyone to shy away from picking us (or accepting an invitation) in St Louis because we are sporting the same drivetrain that failed us twice this season.

Oh yeah I could see how that could be a problem. It would be an interesting offseason project to see how robust a 775Pro (or other similar motor) based drivetrain could be, and what the full scope of possibility is for them (two-speed? An absurd number of motors? PTO? Other stuff I haven't thought of yet?).

Let's just say, all of those are possible!

You guessed our main off season project, honestly the possibilities of running 775pros is just too good for us to ignore.

The biggest disadvantages to a 775 drivetrain that we have noticed is robustness (we still are not 100% sure what happened at Dallas) and not being very good for pushing (can't stay at stall torque for very long). Drivetrain cooling is critical.

Main advantage is that you get the working torque of a CIM in a stupid small and lightweight package. I think our drivebase with no mechanisms attached weighted in under 30 lbs this year, almost half of that being the wheels. The entire robot has varied between sixty and ninety depending on what iteration the mechanisms were on. Want to talk about building an agile robot?

On a completely unrelated note, this discussion has clearly attracted a lot of attention from individual team members.

Can't quite put my finger on it, but there's something about this robot I just really like... Looking good 1296! See you in STL!
