you didn't do the most critical part! you need a layer of rubber cement between the foam and latex! the rubber cement prevents it from peeling off in one piece.

Does the rubber cement be dried for a bit before applying the latex?

@@IbaLabs how about applying it when the rubber cement's "sticky"-ness is similar to that of touching the adhesive part of a clear tape or something?

Love to see some width of wheel and static vs. Dynamic traction content.

You could try cutting some horizontal or vertical grooves into the wheels then apply the latex hopefully that’ll improve the adhesion

I’ve had success applying the latex in a zig-zag pattern, and it seems to last longer before collecting too much dust compared to applying it smoothly.

I was going to say not deep dive then almost at the end I was wondering what a deep dive was going to be. Thank for explaining. Nice improvement for a simple mod. So it appears that a little latex can go a long way. See you in your next video.

Like the weight placement, different spots, how it performed, power to wheels, very interesting...

Unless they were able to get them from the factory coated in the latex it would be difficult and likely require more work than reasonable. From what I understand its just a man and his wife running the buisness out of their home

About to go to bed and now I'm googling robot parts again. Have you tried lightly scoring the wheels a little before coating? Might help the latex bite a bit more

Would be interesting to see a stick test with it as you did it here, rubber cement undercoated, and the tire with the latex going all over it up to the hub as 1 piece You can also make your tires out of either flip flops, from a dollar tree are the cheapest, glue them together and you get a 1" tire, then use a forstner bit to trim down the center enough to get them on the fingertech hubs, or dollar tree has some knee garden pads that are 3/4" thick and perfect for making tires from. all you need is a hole saw in your desired size. combined with this latex this would be a really good way to make a lot of cheap tires you can swap between matches.

you could try to use something like a suitcase scale :)

So you want the CG over the drive wheels

It was interesting how much a difference weight distribution made. If you are making a pusher how would you know how to maximize... Also is there use to having a dynamic axle or something like that so that to keep at least one wheel on the ground even when you being wedged. I also thought it would be interesting to design a robot that could climb on and cling to other robots to force the opponent to try to drive with double the weight- smother them like a wrestler.

There are a lot of things to think about, and many ways to accomplish them ;-) Try some things out!

I tried to roll the latex around the wheel edge to reduce peeling likelyhood, and I found rolling 2 wheels against each other both adds texture to it.

@@RobertCowanDIY Box floor is never perfectly flat, tread on your cars tires greatly enhances its ability to grip on less than perfect surfaces, so until proven otherwise, I'm going with yes? It was likely too much texture on my initial coat, but the major low spots filled in with a couple more light coats. As of now, I'm happy with it.

@@Wagonbacker9Yeah, I've certainly gone back and forth on it. I think for foam wheels, given you have enough weight on them, they SHOULD be compliant enough to squish down into the floor and fill in the gaps? But yeah, who knows. Good stuff!

try pulling instead of pushing: a luggage type scale you can hook into the back of the robot.

I'm sure the mechanisms are similar, but pushing is more representative to what you do in a fight. You rarely ever 'pull' a robot.

How many coats would you recommend? I've got four on my spare wheels, but up to seven on my main robot and I'm not sure what is best. Second, after applying a good sticky coat, I've had problems with getting my robot to steer on the spot at first, like my wheels are rubbing against the body work or the floor. The problem rectifies after a couple of minutes driving around on my floor, but it's not quite as grippy after that. Have you had this issue? Thanks!

@RobertCowanDIY

I do like 2-3 coats, that seems fine/ If you have problems with steering, your drivetrain is probably too weak. They are VERY sticky and you will need to overcome that extra traction. You might want to upgrade your drive.

Because climbing power isn't relevant during a fight. Pushing is, but there's no need to climb an incline.

Have you addressed your issue with the foam tires spinning on the hubs?

@RobertCowanDIY

Yes. I just glue the tires on the hubs. For the new version of Psychotic Break, the wheels are protected enough that I don't really have to replace them unless something really bad happens. So I just glue the wheels to the hubs, and cut them off if I need to change them out. It's not ideal, but it works and is easy and cheap.
