Looks awesome

Ok guys comments please. I got a new work phone and it has a camera so I started a thread.

I'm already over this design, but I will complete it. I have learned so much building it and everything I do now is a lot faster(construction).

The front end requires pipe wedges or similar. Also the chain drive will be sealed in with steel.

Any advise on mounting the wheels to the axels would be appreciated. I have my ideas but please your welcome to give me more ideas.

Thanx, Trent.

Ok, comments that are not just admiring hehe

With a 4wd bot it is generally better to make it as wide as possible and as short as possible for better steering, your current setup is fairly long compared to how wide it is.

The scooter motors should have pletny of power anyway so turning should not be an issue, but it could be worth playing with. That said a longer and skinnyer design typically has more stability in a line, good for ramming!

In terms of attaching the wheels I would go the lazy way and weld a plate to the axle shaft and bolt through that to the wheels.

Plenty of other ways to do it, but I like simple.

im guessing your robot will have a overhead hamer weopon.

The kerrisons hammerbot last event was very impressive minus the chain falling off issue and all dat, was able to self right and when it connected they felt it thats for sure (a lil longer reach with pick/axe would make aiming easier probs)

Thw way kerrisons told me they were to fix chain derailment and something u can maybe do is to weld teh chain to the sprocket that doesnt need to rotate off the sprocket or anything. It is sorta permanent but would work perfectly

Looking good Trent dont know what your axels are made from but you might have probs with them bending being unsuported that far from the wheel .

Simple bot for my first one. No weight left for weapons mate(4X100watts scooters!). The bot is the Hammer , maybe.

Its really just a test bot to teach me bot building

Wheels are floating @ the moment(10mm steel). Axels will be trimmed.

Also wheels will equal distance left to right, front to back. Hows that

Should make it well balanced .probaly a flange like some one else sugested welded to the axel that you can bolt the wheels to might work or a flange that you can key to the shaft would be better

That is sooo Blue Max! Nice work Trent! If you get sick of battling it, at least you can take it down the RC car track I can see this being one robot Marauder will hate, doesn't look like there is anyway to prop it against the wall without a wheel touching something...

Yeah! Very funky, be sure to take a radar gun to it to see how fast you can get it

YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

Actually, where abouts did you pick up those chians and sprockets Trent? And how much? I might be interested in some C&S's soon...

150mm Wheels, 4X100watters, 4:1 gearing. Do the math for top speed, i don't know. I never know what rpm to put to the motors @ seeing there NOT unloaded.

I just looked at your chain set up i think you might get some problems with the chain jumping while driveing the center sprockets .i would have used short single chains to each wheel .
