Interesting. After doing a few calculations, I've worked out that a robot which can do 10mph in a straight line would need a track width of 17cm to spin at 500rpm. It actually seems rather feasible for a FW, and more powerful motors could give it even more potential!Originally Posted by maddox10
That will be a very nervous machine to drive straight.
But my point stands, try to forbid a robot to spin on the spot.
The problem with that idea is when the bot is spinning in place, its not advancing into an opponent and doing any damage. Do some research in to 'Meltybrain' robots, which combine spinning the shell with driving. On the few occasions builders have gotten them right, they have been very effective.
Since you cant advance on your opponent, and you are entirely relying on them, you will get very limited bite, and at 500rpm you wont be able to do much damage, even when spinning 13.6kg of steel.
If you fitted say 4 drill motors in a short but wide 4WD config I am sure you could get a straight driving robot that did 500rpm on the spin. Build a test bed. See what happens IMO.
Help needed please. I want a bit of my wheels to show on both sides so it can be driven upside down if flipped. I am making my own motor mounts but can't work out the measurement to make the wheels show. My wheels are 120mm and the height of the bit including armour is 102. What measurements do I need to work of to make the mounts sit right so wheels protrude each side. Hope this makes sense!?!?
You need a 51mm axle height in that case - the measurement will always be half the body height regardless of how big the wheels are!
Super. Thanks just couldn't work it out lol
