Hi. My team has a mobile goal picker upper. it is the standard design.(2145z 's design(Kind of)on youtube) I am wondering if we could attach a bar connecting the back to each side, and then adding 2 smaller c channels closer in to power it(With gears). I do not have that long Axels, so would it work the same if we have the gears closer together? I can add cad designs if needed.
I do not fully understand what you are saying, and pictures of your design would be very helpful

The mobile goal goes on the angles, and the gears would go on the c channels sticking out. would something like this be ok?

This would work fine. The reason teams have some of the gears farther apart is to keep the lift more stable, but that should be stable enough unless you are getting hit by another robot. If you find that it isn’t stable enough, you should add a cross beam from where the gears are to the corner of the part where the goal will be.
I do. The picture was just a quick cad design. I also have more aluminum supports. I was just worried that it would not have the strength with only 1 motor
You can rubber band a part of your forklift to a place on the robot if it is not strong enough, but a 1:7 gear ratio should be more than strong enough
Ok. Thank you. I already have the rubber band too
could I do any less of a gear ratio? That is a bit big. what about a 1:3? (metal gear to 36 tooth high strength) I can do bigger, but I just do not want to make it super slow. I just want it to work.
1:7 or 1:5 would be the ideal ratio (for a 100rpm motor). 1:3 would definitely be too fast, and there isn’t really any reason you would need the extra speed on a back mogo lifter.
Ok. Thank you. I do not want extra speed, I just want extra torque, and power
