My team was thinking of using this concept to climb to the 3rd level of the HAB platfrom. Is there any way to make an elevator that can both go through the chassis and extend upwards to place balls/hatch panels on the rocket? If we could use our elevator to climb it would save a lot of weight. I believe this will be the most reliable way to get to the 3rd level, other methods rely too much on CG and tipping.

We are using a separate one. I’d like to see how you do it with one that would be interested. To save weight we are 3d printing it out of HIPS and Nylon.
Are you going to still use aluminum for the tubes? I would be impressed if a 3d printed elevator could support a 150lb bot

We need to connect them as we can only print something that is 10.5 in long
Here is the design
Its Printe ouf of HIPS. We got no deflection on it subjecting it to 340 in/lb torque in any direction (The max of our tester so we do not know where it would break) and we lifted with that a 100 lb weight lifting weight with no problem and decided to not test further as if we go to the breaking point of it we might damage the floor having a couple 100 lb crashing down and we use one of them on each corner of the robot so each one will roughly lift 1/4 robot. Now that piece weighs 90 g it will take 12 for the 4 lifts. They are grabbed by 2 pairs of Nylon gear pairs that intermesh with each other and the one from the motor. This was part of our off season project to rebuild last years robot out of 3d printed Plastic and was part of the climber design for last year. The center takes a 1/2 in anything (PVC, aluminum, steel) either a short piece to join 2 together or all the way through depending on how the weight goes. This particular tested piece is printed out of HIPS (High Impact Polystyrene
That’s awesome! I love the idea, seems like it will work. Did you print it vertically or horizontally?
Here are some pics of an experiment working on an Omni wheel only Skateboard 3d printed with Aluminum churro supports to carry 120 lb of weight lifting weights. The frame, the 3d printed planetaries and 4 Cims and wheels came in just under 30 lb (without electronics and battery which is 10 to 15 lb less than a similar configuration on the Andymark frame with Toughbox Minis.
Well we will see what will be done this year depending on what the kids design. We know the elevators will be 3d printed and we are using the planetaries too as they give us more room if you are interested you can follow it on youtube
I just recently posted a video as to how to design the rack part. (and there are a couple on the gear boxes too.
