As usual, I've stored up a bunch of questions, and I'm sending them out into the
great beyond in the hopes that, amidst NXT battles, they will find their answers
and return to me ;-)
Question 1:
Are the omniwheels at <http://www.charmedlabs.com/productsmain.htm> worth
US$9.00? I am considering the purchase of 5-6, and $9 seems a bit much.
Question 2:
To the GBC guys: How do you efficiently project a ball from a Lego robot
several feet? I would like to build a semiscale model for my FRC team, game
animation here: <http://robotics.nasa.gov/events/first/AimHigh-Sml.mov>
Question 3:
Anyone ever build a robot driven by a ball of any size? This would entail a
ball in a setup similar to a mouse (the ancient kind, that actually used moving
parts as opposed to light:-). If so, could you send me pix or a description of
how to start? I'd like to use the Lego balls, but they may be too small for
practical use.
Question 4:
Does anyone know if there is a source for Lego-compatible mecanum wheels?
These are similar to omniwheels, but the rollers are at an angle to the wheel,
allowing holonomic movement (and regular turning!) with just four wheels.
Wikipedia link here: <http://en.wikipedia.org/wiki/Mecanum_wheel>
I am pretty sure that those are all the questions I had. Who knows, maybe some
of the answers even apply to the NXT...::goes off mumbling something regarding
an 18yo age limit on the MDP::

| (...) I bought a bunch of them for a flocking project and have been generally pleased w/the purchase. However if cost is an issue, you can make your own from these: (URL) (18 years ago, 25-Jan-06, to lugnet.robotics)

| (...) Well, there's a few methods that have been tried. The first was just to have two closely-spaced wheels spinning rapidly - when a ball falls between them, it's shot out. This seems to require heavy wheels and RC motors (gear motors have been (...) (18 years ago, 25-Jan-06, to lugnet.robotics)
