Its a good start but theres lots of things you could make better
Heres a pictures of the stuff you can change, there is probably more that i cant see from the angle:

Hi sorry this has nothing to do with pmkvās robot, but would a rack and pinion with two bevel gears work for a mogo clamp?
Great idea, but bevel gears tend to slip. Iād say that if you donāt choose pistons, maybe try a toggleable ratchet? Thereās not much option other than piston in my opinionā¦
Never mind I thought about it more and realized it wouldnāt work.
Do yāall thing an active brake (plate that pushes into the ground and prevents robot from moving) would be useful this year? I feel like having a brake would fit well into the current goal-hoarding strategies since it pretty much locks you in place.

Thatāsa good idea! Maybe use pnumatics and a locked flex wheel.
We donāt have any pneumatics or anything but I figured it out
Hereās my robot so far:
Iāve only had about a week and a half so far to build it, so this system is obviously not optimized, and is more of a prototype than anything. does anyone have any ideas on how to improve the intake though? It āworksā but itās not very good at picking up without me putting extra force on the ring (might be fixed by switching to the smaller more flexible wheels), and itās annoyingly close to the size limit, especially considering I havenāt built the hood yet.
some notes for any suggestions:
-the 4 remaining motors are reserved for climb if at all possible
-cg shouldnāt be an issue, as thereās more mechanisms that will be near the bottom of the robot, but I still want it to be as light as possible because blue motor drive
-I want to get rid of the stupid chain tensioner thing i made if possible (it accounts for the arm not pivoting around the main axle, but itās pretty janky and destroys precision
-the chain tends to slip against the donut sometimes, probably due to the random screws sticking out everywhere. I donāt have any flat pieces of plastic to work with so iām not sure how to fix this.
-kiwi drive is already programmed and tested, dont worry about that part
thanks!

The chain tensioner could be removed by moving the second intake bar ( the one with the gray wheels) onto the same axis as the motor (or another source of power like a sprocket).
Example:
See how the axis powering the front gray wheels is the same axis that the bar holding the front gray wheels pivots around? This removes the need for a belt tensioner because the distance between the sprockets remains constant.
As for the screw heads sticking out into the path of the donut, Iām not really sure how to fix thatā¦
