Team Eventorizon: Build Diary

Has anyone ever run one of the Banebots 18V RS775 motors off a Electronize FR30HX? The numbers look ok but I am not sure the ESC will cope at 22.2v... any thoughts?

The Electronize are rated 6-24v, so should be fine.

Its the ampage I am more worried about... : :uhoh:

Well, apparently they have a stall of 130a, at I assume 18v? Seems crazy high to me, but the 30a series of Electronize can, going by their website, take a peak of 570a and handle 90a for a short amount of time.

A single one would probably be fine, as it's likely (unless something goes very wrong) that the wheels would just spin before the motor would stall completely, saving the ESC. Though, in the arena, anything can happen. :lol:

I run the 15a ones with 30a fuses and never had a problem, fuse blows way before the gear

Fuses it is :)

[attachment=0:1sfjp6gi]Design 6 V2 QC 01B.jpeg[/attachment:1sfjp6gi]
2x Banebots 18v 16:1 P60 DRive motors with pairs of 124mm wheels
2x Electronize FR30HX
3x 5 Cell 2600mAh Lipo's, two wired in series to drive the weapon motor
1x Hk-40350 800kV Scorpion brushless motor on a 3:1 ratio giving around 9500rpm output
1x Scorpion Commander 50V 130A OPTO ESC

Chassis is cellite 620 with 2x 2mm Ti 2 top and bottom and 20mm HDPE around the edges.

Current weight - drum ~ 9kg

Everything is REALLY tight inside so I am going to build it in wood first to see if I can even get it all in there! It should all go but it will be very close!

Yay!

Also what happened to the disk design that didn't look like a carbon copy of Dave's new drum bot?

You mean the single tooth design? We are still going to use it, I just could not be asked to CAD it up, I was getting tired...

I know its very similar to Dave's, which is similar to Jamie's, which looks like the Riobots machines, which looks a little like Blade from RW series 3, which is probably based on something from the US, which will have been inspired by a lawn mower which was inspired by the old rotary traction engine combine harvesters... but hey it's a good design style :)

So its not a carbon copy as you rightly point out it pretty much is, I have deliberately changed some aspects it so it will be different to Jamie's and Dave's... the drum overlaps with the wheels, the chassis is much shorter as a result, different weapon motor position to try and make the robot as small as possible, motor ESC's under the drive motors to reduce the length even further, but of course it might not even be possible to make as its all so tight!

Does anyone know the weight of a 75mm Robochallnge wheel with the bolt insert?

Or even better, one bolted to a Gimson GR01?

Cheers
