lol whats that thing in front cant quite tell

Re: pic: Idea For Hulding
 

why would you spin the ball? (besides for fun, i mean)

Re: pic: Idea For Hulding
 

looking at the arrows drawn on their spinning wheels, i presume that its supposed to spin the ball so that it would take less force to shoot it off because it will be 'rolling' off of the ramp partially by itself.

Re: pic: Idea For Hulding
 

Using rolling for more "go" is a good idea, but wouldnt the friction and resistance going up the "rampway" basically case it to be null in void?

A ball thrown with a frontspin over the Overpass will enable it start down the track on it's own to a certain extent. (In a perfect uncluttered track scenario it would bounce off all of the angled walls at the ends of the track and come back around to you so you can score it again.... w00t! But... I doubt that will be happening consistently, if ever as pefectly described.

A ball with a back spin will make it stop as soon as it hits the ground (or come back towards you after you throw it.. but not so much with the properties of this particular ball). This will give you more control to pick it up sooner after you throw it than the scenario above where you have to chase it down.

It all depends on how fast you want to hurdle, and what your intentions are.

Remember the Trackball still needs to pass your alliances finish line before it can score over your own again, so it may matter in the long run which one you want to go with.

Because theoretically, if you store up enough angular momentum in the ball, it can propel it self up the ramp once it is pushed forward unto the ramp.

This is a very interesting idea.

I spy physics equations. ;)

If he says its interesting, then it MUST be interesting :P

Before the height restriction was lifted, one of my ideas for removing a trackball from the overpass on the opposing alliance's side of the field was variation on this idea. Use a wheel at the maximum 6 feet height. It will contact the bottom of the trackball. Spin the trackball in place -- as it is being lifted slightly, it will not stick on the overpass rails. Once the trackball is spinning as quickly as you can get it to go, suddenly stop, or even reverse, the wheel. Bam! The trackball jumps off the overpass in the direction it's spinning.

We prototyped this. It works. But other schemes that reach higher can work quicker.

Very good. I wondered what your undisclosed ideas were. Couldn't ask in the old thread because it got shut down when Update 1 removed <G36>.

lol 1 lb is not 0.37324 kg, its ~454g

Re: pic: Idea For Hulding
 

Someone obviously looked up Troy pounds by mistake.

Or maybe not by mistake -- the measured weight of our trackball is about eight pounds avoirdupois...which is about ten pounds Troy.
