I believe so, but we would need to check with @tashic.  I’m not in front of the computer now, but I can try when I get home.

Nice! A new build incoming! That belt drive should make it a lot easier to build spinners than it currently is. Any other changes we can look forward to?

1. Driving.  Everything has to drive well and believably, from beetleweights to lightweights, to heavyweights.  Botlab and premade robots.  Its been a challenge to get everything working well across all of the weight ranges, particularly with spinners that aren’t quite balanced that throw robots into a wobble.  My first priority on this build is to clean everything up and make everything drive well.

2. Now that the spinner blur works, I can finally get to a proper kinetic energy-based damage system that doesn’t rely on the existing physics system.  It was a big challenge to compute the volume of revolution for a user-defined weapon, but it should make it possible for you do use something like the Spinner Damage Excel spreadsheet http://www.brjackets.com/robotics/files/spinner%20spreadsheet.xls to compute weapon energy for use in the game.

Not gonna lie, I was really hoping for some sort of belt drive and you guys have more than delivered once again! Cannot wait for the next build!

Out of curiosity - can the pulley system be 'doubled up' to potentially create two shafts powered by one motor? (For example, two wheels powered by the one motor)

Its a little impractical, but is something like this what you had in mind?

Not quite... I was thinking more along the lines of how a lot of four wheel drive robots work, with two motors connected to two sets of belt systems, in turn powering four wheels in parallels of two. (I could draw up a quick diagram if that helps??)

I love seeing what you did there though! It's gonna be perfect for drum spinners and dual vertical spinners!
Damn I should probably put something fancy in this bit huh?

Gotcha!  Here's the BattleKits Middle Weight configuration:

http://www.battlekits.com

I just tried it, and the system isn't set up to do that yet, but @tashic tells me that it is on his list of things to make work.

In this version, if a pulley is attached, it can be the only thing attached to a motor.

Yes! Exactly like those! (Apologies - work has been a stress fest this week; my mind is barely hanging on at this point haha!)

Ah I see no problem! I was only asking out of curiosity haha! Still living for what you've displayed though, your entire team and you are doing an AMAZING job!

I just thought about it a little more, and it looks like you are looking for a crown gear or bevel gear.  No way to do that, and we hadn’t really planned on it...

You might be able to accomplish the same space-saving effect with a pancake motor though.  We can pretty easily put a flatter motor in the game.

yeah, as current motors are not Hori spinner friendly

Agreed.  I try to put together a shorter motor or two this week.  Anyone have any preference for weapon motors?  I am looking at something Etek-compatible currently.  At a minimum I should be able to come up with a mock-up of the right dimensions, weight, and motor characteristics.

Just a nice variety of shapes, sizes, and power levels, rather than the two (plus BW motor) that we have currently. Etek and pancake motors would be nice, maybe also an R-shaped one like the TWM3R in DSL. NPCs, too, maybe?

Also, just a small thing, but would it be possible to put the motors' performance stats (like horsepower and torque) in their descriptions? Or are you going to wait until their stats have been finalised before doing something like that?

IIRC, they're about the same diameter as an Etek, but slightly thinner. Storm 2 used LEMs as drive motors at one point, but they're heavy enough that you'd need WhammetNuht's system of "one motor powering two/three wheels" for them to be practical in an RR2 rammer.

Just looked up lems. I thought they were actually huge, but i see they have variety. Nice

Will do.

You are correct about the reason for not putting specs in the description.  Up until now I have been fudging numbers all over the place to get everything to work.  Now that the spinner blur is functional, it is possible to simulate real-life speeds.  A motor spins a bar at 3000 RPM?  No problem.  The question now becomes which specs to include.  Do we got full on simulation, with Kv values, or do we just do something simple like power at rated voltage?  What about torque?  Weapon tip speed at full spin-up?  Kinetic energy?

Maybe there is a kinetic energy, RPM, and tip speed meter in the test cage that allows you to see the numbers as you spin up, just like you would have when bench-testing a real robot?

Oooh, that'd be handy. We'd potentially then be able to set tip speed limits for tournaments, like Extreme Robots and (IIRC) Battlebots have. Might help balance out the meta a bit. How would you differentiate between weapon motors and drive motors for those meters, though?

That’s on my list for Monday.  I was thinking of adding a “wheel” tag to wheels so that it knows to not consider a wheel a weapon if the wheel is properly attached to the motor or pulley.
