Do you like four or six or maybe even eight or three wheels whats the best for complicated or for simple?
I know what I like but just to see what you say:p
This thread is more appropriate in the General forum. This is not a question which requires an âofficialâ technical support response.
I have moved it accordingly.

last year we used 6 of the 4" wheels powered by 4 motors and gear drive. It was a beast, with the ability to outpush most opponents, and it was also quite fast in turning and acceleration fowards and backwards. It also had the ability to easily get onto the platform.
This year, we are planning to do the same, although I am tempted to try 8 wheel drive.
Yah thats what we did we had 6 wheels and 4 motors:cool:
Our team employed 4 of the 5in wheels without treads, powered by 6 motors with a 7/5 torque increase through gearing. If I recall correctly no robot was ever able to push ours, and very few were significantly faster.
It really depends on what the challenge calls for. This season is significantly different from last year. Both agility and torque are very useful in this challenge; how many wheels are used is probably quite secondary to what type of motor/gearing system is used. One that can switch from high to low gear very effectively could be immensely useful.
Ya this year you DODNâThave to get onto a platform:D but i still think you should be able to get over rings in case they get under you.
any one know why the motors âtwitchâ because i dont have any optical encoders so i had to make some distance sensors with limit switches and motor âtwitchingâ might really screw it up
the twitching is radio interference, get away from other electronics, and keep more than 5 feet between your controller and the bot. the twitching should stop
lol, âget away from electronicsâ where i work with vex i have my other robot, a computer, a wireless reciever, router downstairs, 2 other computers in the house, a huge pile of active and unactive electronic experiements or projects and probably 5 battery chargers (duracell, energizer, pureenergy, power pack, and a basicx hookup power adapter)
Why does everybody hate 3 wheeled robots?
I know they stink but I didnât:cool: think you hated them that bad.
3 wheeled robots generally are less stable and easier to push around. The number of wheels you want to use all depends on what you want to do.
if you use a 1-1 gear ratio on each wheel it would be epic. I think it would have a bit of trouble turning unless you use omniâs though, otherwise it may create too much drag. Either that or you would need to use a differential on them.
I may be wrong though, iâm just thinking this out in my head.
Like you said, it all depends on what you want to do.
it depends on what kind of drive.
If you use a 3-wheeled holonomic, which is what I most commonly see outside of vex the stability is pretty awesome. It still getâs pushed around though, being that it has little friction, but if you want a speedy robot that can spin in a circle like a top, then thatâs your best bet.
Starter kit has a 3-wheeled robot in the pro-mix scheme. Maybe someone likes it.
