We’ve taken our Telescoping Arm design and adapted it to perform climbing for the 2024 FRC Game, CRESCENDO! The new design is built off the same tube-in-tube rack and pinion design as the original, but comes in a smaller form factor and adds several new components to support an efficient climb. ROB-17562 includes components to support both hooking the chain and for latching the arm once a successful climb has been achieved.
Love the latch. That’s a big value add vs others in the market place and the existing ability to drive both ways vs CF springs is still a nice feature and is relatively refined at this point for FRC use.
I imagine it would not be too hard to attach a servo to the latch with a piece of string (string to isolate the servo from any shock loading in the latch)
Any plans/insight on an actuated latch with a servo vs pneumatics?
Have you durability tested this? We had a very similar design for our arm last year and were thrilled with it, but we stayed away from it this year because we were concerned the sprocket on the wall of the tube might bow the tube and/or hollow out the holes in the aluminum over time when you are lifting the full weight of the robot.
a few weeks ago I designed a climb that was exactly like this one ,but i thought it was unreliable to hold all the weight of our robot on the steel piece between the gear holes, so you have found an excellent solution to this problem. I wish i had thought of this solution earlier
They have used this method on climbers and various telescopes for 1756’s robots in 2019, 2020, 2022, 2023…
My team used a variation of our own of this design last year and will be this year and the rack tube hardly wore at all for us over the entire season + offseason even with us slamming it into the wall all the time last year.
