Team Shock's new Beetleweight

[teamshock]

Since its looking like there will be some beetleweight activity at the next AWS I have decided to go for a proper competition one and that meant it was time to make a vertical spinner. After playing around with the CAD for a bit I came up with a design that should work and allow me to use the rather nice 10mm thick, 500g single tooth discs i have. The bulkheads have been 3d printed now to test the concept and if it seems like it will work I will CNC it from aluminium at Uni.

This is how it looks currently (with the 6mm disc fitted)

Armour: Titanium/ Steel or HDPE
Drive: 2x pololu 20.4:1 HP motors
ESC: 2x Botbitz 10A
Disc motor: 28mm NTM outrunner
Disc ESC: 30A Red Brick
Battery: 3s Lipo

ive got the same drive motors on mine, not sure on the gearbox thou but they are are nice and nippy

[harry hills]

Your ones are the ebay 1000rpm ones.


Looks great Will.

After taking part in the beetleweight competition at AWS 44 I have decided that a few changes need to be made to mine to make them a little more reliable and solve the issues that appeared at the event.

Soundwave worked pretty well overall, the disc mechanism is excellent and provided some big hits and plenty of damage. The drive is also very good but it simply is not big enough to contain a large enough battery.

I have redesigned the chassis to have a larger back end to house a new 3s 2200mAh Lipo and free up some space for the electronics. The previous one was only 1.1kgs so there is plenty of weight. The sides will be covered with 1.5mm steel again as this withstood direct impacts from RPM with only minor scratches. This time the chassis will have proper spacers machined to make sure the whole thing stays together properly.

This is the new version alongside the old



I am also working on a vertical spinner after getting hold of a new disc (not the one shown here). This will have a larger brushless to spin it but will largely be the same internally as Soundwave.

Great, more spinners...

Looks good though

Spinners in this class are really quite easy to make so expect a lot of them. But you saw how well even 5mm was able to take the hits as the robots didn't weigh enough to let the weapons dig in. Even aluminium might work if it is designed correctly.

Looking good though Will. That vertical looks potent!

[Niels - Team K.a.L.M.]

I know, after a pushbot the spinner is one of the easier designs alongside the axe or even the servo operated lifter.
I do not dislike spinners in general but I do like to see different types of weaponry (in one team), just my 2 coppers.

Those new designs look great will, should be good

The chassis pieces for Soundwave 2 and Inertia-B are being laser cut at the moment. So hopefully they'll be back pretty soon so I can get them going for Stevenage. I've opted for a slightly larger brushless for Inertia this time to make sure it has no trouble spinning up the bigger disc.

Some beetle progress.

The chassis pieces for Inertia and Soundwave have arrived. I now need to cut the armour panels and start welding them together. I'm also trying some new printed wheels in these to see how they perform.

[Revsmin]

Looks great Will
Who does your cutting BTW?

[teamshock]

Thanks Jarvis, I use Emsea for all my cutting now and they've done a great job

[Revsmin]

Cheers

[Mega Masher]

What did you use for rubber on the wheels will?

[teamshock]

Some more progress

Everything is now here for both machines so the build will start tomorrow
