Re: Team Eventorizon: Build Diary

Its a Goal, it doesn't mean we will succeed but it combines various elements of other machines together to give it, what we think is, the best chance

Current weight in solidworks is 5.5Kg... We might be able to have a Cluster bot at this rate!

Re: Team Eventorizon: Build Diary

you going to put any celite or whatever its called in their Alex?

[Eventorizon]

Re: Team Eventorizon: Build Diary

Yep the base, uprights and the the bottom layer of the armour is to. We are going to layer Ti on the top faces but the machine is so light, less than 9Kg all in, that we are considering putting a layer of Hardox 400 on every side. The only problem with that is bolting it securely to the rest of the machine!

Here we go, the first all parts pictures!

With the lifting arm fully extended...

Up close and personal...

Given that it currently weighs 9Kg, we are thinking about adding a layer of 10mm Hardox to all sides. This will be most critical at the front to stop spinners getting in between the back of the lifting arm and the front of the robot!

Suggestions and improvements welcome

Re: Team Eventorizon: Build Diary

that looks cool! nice design, but maybe on the lifting are, you could have an extra bit folded over on the corners, to make it more ridged , and less lightly to get pulled from behind and bent from an impact on the corner of the wedge (if you dont get what i mean, have a look at tornado's wedge, im sure its on google some where, or if you rember tiny toons wedge, how it is bent round the corners) i just think that will make it even more spinner proof! but looks awesome still, And your a good CADer!

Re: Team Eventorizon: Build Diary

will be a pig to drive with the wheels that far forward

Re: Team Eventorizon: Build Diary

It would drive around the weapon (such as 360 and Venom/Hypno-disc and Razer did), meaning pointing it would be easier than if the wheels were at the back. Only issue with the drive might be that the mass of the machine will be behind the wheels, so when you turn you'd build up lots of energy (several kilos of robot), making stopping mid-turn hard. It would tend to over-steer, I think. I guess that would make it hard to point. Hm.

Perhaps, to make use of that swinging mass, stick a massive great thwackbot-style axe on the back? Like Barnsley-bot!

It looks great, and it's certainly different. Could it not get stuck on its side?

They're all 4wd, 2wd will be impossible to drive, the back end will just constantly kick around and oversteer.

Re: Team Eventorizon: Build Diary

The thought behind the steering was it would be like Venom's or 360's with it pivoting around the front wheels rather than the middle. This should mean that we can keep the lifting arm under another even of they try to escape. Though a pendulum effect is a distinct possibility, and will definitely look into the stuck on its side issue, thanks Ellis!

Re: Team Eventorizon: Build Diary

As Alan said.. 360/venom drive well due to 4wd skid steer...

Diablo has wheels at the front and a ball transfer at the back and it's totally un driveable...

If your making this robot to go against spinners... Cover the wheels... And angle the edges of the wedge down to the floor... As it is, it wouldn't take much horizontal force to rip that arm off... Remember the force being pushed sideways onto the tip of your arm will be even greater at the pivot point due to leverage.

Re: Team Eventorizon: Build Diary

move wheels back and make sure there are no catch points for horizontals. if i remember correctly ironside has a hardox 4mm strip bent in an octagon . corners have a large radius so there are no catch points for horizontals to catch on. also am i right in thinking that having a large weight infront of the wheels would help the steering?

[Eventorizon]

Re: Team Eventorizon: Build Diary

There are still things missing all over, maybe 80% complete. And there will be issues with any design but moving the wheels back would probably be a good idea. Though this isn't my machine its my dads so in the end he has the final say, and he is the one that has to drive it as well!

Re: Team Eventorizon: Build Diary

A gyro would help the oversteer issue, but it would make your ESCs work seriously hard, having to fight that swinging 13.6kg arse constantly.

Re: Team Eventorizon: Build Diary

Designed a new single tooth disc for Conker... 2.5Kg of Hardox 400. I should Rename him Talon!

Just noticed I have missed the hole to bolt the disc to the pullys... woops
