Gear Ratios High Hang Help

Our team is unable to score a high hang consistently. Our high hang only works with a fully charged battery. Even with a fully charged battery that the hang is slow moving.
We are using two motors with two sets of gears on each side of the axle Our two gear ratio is the smallest gear with the largest gear. The motor is attached to the smallest gear. I see a lot of teams with larger robots then ours lifting their robots with ease. Any suggestions would be greatly appreciated.

Little thing that’s really important is the distance between the hook and the center of rotation of the yard. Perhaps that can be adjusted so you get better Lyft.

My kids like the 1 to 15 gear ratio with 2 motors for the arm. It’s worked on most of the robots they’ve built so far this season. See 6:50 on this video. The new arm isn’t done yet, but you can see the 1 to 25 that they abandoned.

You can try something like this. It’s got the benefit of a good gear ratio and a shifting ‘balance’ point. Helps level out the robot, which get another inch on the hang height.

Thank you for your replies. The kids have modified the robot and are able to high hang.

How are you able to have 2 motors turn 1 axel?

You can simply connect them to the same axle.If they are not spinning in the same direction, be sure to reverse one of the motors directions

We were using ModKit to program controller so 1 button operated both motors. But Modkit would randomly stop motors from working, so we stopped using it. While we figure out how to do the same with RobotC, we are trying different gear ratios. 1/25 (thru compound system) was too slow and rounded out the centers of the gears. 1/15 worked about 5 times before it also rounded out the centers.
We know the robot is heavy - 6 motors… Do you have any suggestions?

Use a shaft locker pinned to your gears. This will take some of the load off the shaft hole in the the gear.

Another option is to double up the gears on each shaft. One of my teams did this to reduce the load on each gear and reduce the chances of the gears slipping or becoming misaligned.

Also, if you locate the brain higher on the robot, near the arm shaft area, it will hang much easier. Be sure you are running your motors at 100% speed.
