Re: Team Eventorizon: Build Diary

I have not been able to find a way of making reliable and lightweight tracks and I dont think anyone else has either. I have not seen any tracked feathers anywhere. I know someone here is prototyping one but it keeps throwing its tracks. But you are right, tracks would give much more traction!

Armoured version with more grip or less grip, less armour and a weapon... Should of just bought 540 lol


Are you using magnets? If not don't go crazy on thinking more contact area is a better thing... You only have 13.6kg pushing down on your wheels... So 13.6/4= 3.4 kg per wheel (ideal situation) if you spread that over a large area... It's not much weight pressing your wheels into the floor...

that he should have done

Re: Team Eventorizon: Build Diary

We ended up with 3 designs that looked very 540-esque. But we don't want a copy. 540 is a perfect example of raw pushing power but we wanted something different so here we are. We did have a storm 2 type one, without the lifter but my dad wants some kind of active weapon rather than just a Full Body Hammer, and we also went through things like sewer snake, 101, All Torque, Tornado etc

Put simply we want something different, if it doesn't work like we planned then never mind. All we can do is test out ideas. In then end we are just after some fun and to improve out skills, if we can make a competitive but interesting robot at the same time all the better

Oh and no magnets as yet. but we could fit some inside the side pods if we wanted to... I think

Done some work on Conker...
[attachment=0:36ptytsl]Conker MK 2.2 800x800 Crop.jpg[/attachment:36ptytsl]
Its beginning to look more like Tormenta with each alteration...
Sides a now 2mm Ti at 50 Dgrs, might lower that a little more. Underneath is a series of cellite buttresses to support each face. This set up will be used against non spinners so that we can get underneath them easily. Then the idea is to make strategic holes so that when facing spinners, sheets of HDPE can be bolted on to to absorb the hits.

Re: 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?

Re: Team Eventorizon: Build Diary

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

Re: Team Eventorizon: Build Diary

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

Re: Team Eventorizon: Build Diary

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.

Re: Team Eventorizon: Build Diary

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

Robot Design 6
[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!

I am going to build it in wood

Yay!

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

[Eventorizon]

Re: Team Eventorizon: Build Diary

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!

Re: Team Eventorizon: Build Diary

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

Or even better, one bolted to a Gimson GR01?
