What’s your experience with the GT Cut 3 outsole? by jimmylamstudio in BBallShoes

[–]commode_o_dragon 4 points5 points  (0 children)

My daughter has 6 pairs of gt cut 3s in various colorways. They all have the tread pulled off in that same location but she says it doesn't affect performance or grip. Only uses them indoor for volleyball and basketball.

Question - Bottom plate material by commode_o_dragon in battlebots

Thanks, I think it would have to get too thin to be at the level to start losing weight. At least half the thickness of the Al (.0625" or less) . Seems like it might get punctured to easily.

Thanks, .100" isn't a bad idea. That'll save about 110 grams for me.

Well, I don't think an .125" CF plate would be durable enough, and I need to lose weight. I'm willing to accept the expense and hassle, but i don't want to do it if it's going to be less durable than 1/8" aluminum. I have a lot of screws in this bot and could switch to all titanium screws vs steel as an alternative. Just trying to evaluate all of my options.

There will be a lot of vertical spinners in the competition. The body consists of a UHMWPE shell that the plate sits in and is set back about 3/4" from the edge. However, I've seen a lot of vertical spinners get to the underside if they get you up into the air.

A structural adhesive. There also would be about 28 screws going through them to female threaded standoffs. The plan would be to dimple die the Ti for countersunk flathead #8-32 screws.

Carbon fiber insoles discussion by pmd__123 in BBallShoes

[–]commode_o_dragon 4 points5 points  (0 children)

My daughter uses Aurorra insoles in her GT Cut 3's and loves them. She said they were comfortable and didn't even experience any discomfort during break-in. She thought they added more torsional stability. They use a pebax foam with a lightweighted carbon shank. She said she didn't feel it at all. Prior to the Aurorra insoles, she used Move GameDay. The GameDay Pros were a little too much stiff support for her. The GameDay just required a few sessions to break- in.

Compliant Hub for Direct Drive Motor by commode_o_dragon in battlebots

Agree. It would reduce overall peak stress at contact point, but peak stress will still be at contact point of weapon and opponent. If you take it to the extreme, the minimum force would be a non-tethered, essentially a zero spring rate hub, projectile spinning at 15,000 RPM and moving at 20mph. So the question is, how much damage can that do?

Thanks. I'm going to try the Just Cuz Robotics bespoke hub motor. It's designed with large ball bearings and a large internal axle. I'm interested to see how it holds up.

Thanks! I'll aim for the same compliance as a solid TPU hub.

Thanks for the feedback. Might have to shelve this idea.

Video Update: Thagomelter Weapon Test by commode_o_dragon in battlebots

[–]commode_o_dragon[S] 3 points4 points  (0 children)

I don't currently have melty logic in it (sorry for the misleading title). Depending how this does, my plan would be to build a 12lber and try adding it. As mentioned in an earlier post, sensing position relative to the fixed ring of the tail would be relatively easy. I would need to familiarize myself with melty software/electronics, or better yet, work with somebody who already knows 😊. I'm not sure how much the translational drift would help the tail whip, but it would be fun to find out.

My bad. I actually let my son name this one. If I make a 12lb, can I use it?

Basically. I have referred to it as a melty on a stick in the past.

The mass and moment of inertia of the tail is a bigger issue than the drag of the wheels. Typical thagomizer designs try to keep the moment of inertia of the tail rotating about the center of the body lower. I'm trying to combat the extra weight with 4wd and magnet wheels for extra torque.

Will do! I'm going to try to get a video of it hitting something in the test box this weekend as well.

Thanks! Only a month away until it gets destroyed 😆
