Vertical or Horizontal?

[Guest]

Hello,

I was wondering on opinions about horizontal and vertical disks. I know verticals pack more inertia but the gyroscopic forces are immense. Any Opinions.

Thanks,

Vertical or Horizontal?

verticals pack no more inertia than horizontals. That is down merely to the design of the disc and speed it runs at.

Horizontals have to do damage to be effective whereas a vertical can just flip opponents around.

The gyro forces act against a vertical as you have a wide wheelbase whereas they actually help a horizontal stay horizontal when it is flipped.

Its all about what you would rather build more than anything else.

I always wonder the outcome if the 2 come together, would a horizontal cause more damage by hitting a vetical from the side.

well that happen at euro champs but i cant remember who won

A vertical disc head on with a horizontal is all just a big gamble really. If they are of similar specs its all about whos tooth hits the other disc first!
As Gary says, a vertical disc is good for flipping a robot over aswell, and it often causes damage to the underneath/bottom corners of the robot which useally twists the chassis alot easier than a horizontal spinner. But then again, a horizontal spinner is usually better against wedge robots head on - and it looks really spectacular when both robots spin across the arena after a good hit

The horizontal vs vertical is an interesting question but as grant says, its all about who hits who first and generally comes down to what happens in the space of a few hundredths of a second.

Vertical or Horizontal?

If a horizontal disc hits an object equal forces are appled to the disc and the object (Newtons laws etc,) hence Hypno Disc throwing its self sideways and breaking down on a number of occasions.
When a vertical (spinning upwards) hits an object much more of the force is applied to the object as the robot cannot move downwards (assuming its on a strong floor).
So in terms of effect vertical wins but as has been mentioned steering it can be a problem.

Ive just realised there is a sort of acception to the rule in the hoizontal spinner/Newton stakes!
Little Spinner! Because it, uniquely, has the spinner axis between the drive wheels, on the same line it gets a much reduced sideways jolt when it strikes!

Steering can be a huge problem for horizontal discs too. look at warhead for example. Mike, thats not always the case. it just means that all the force going into you oponent also goes through you axles etc and so some things need to be built stronger. I believe that you can get more of the energy in a horizontal spinner into the opponent due to the friction on the floor. Alot of it depends on the design, but its basically what ever you think looks best, fits in wih your design etc etc.

Vertical or Horizontal?

Basically what happens with horizontal spinners is the opponent flies in one direction and your robot in the opposite direction. A vertical one does the same bit that one has the arena and the whole globe underneath it to help it stay put.

Apart from that you have the helicopter effect that if a robot has a disk horizontal spinning anticlockwise the robot can turn faster to the right than to the left, and clockwise vice versa. Warhead is a prime example of that.

Overal vertical spinners are better manouverable but they have the problem that one wheel will start to lift at turns if the disk is at high rpms due to the gyroscopic effect.

btw, that is why with Adrians spinner the wheels are as wide apart and as close to the disk as we can fit them without going overboard with weight. It helps enormously with the driving.

So would you recomend a drum, vertical spinner, or horizontal spinner. I know it depends on what I would like but Im thinking attacking and a good show for the audience. Thanks for all your advice by the way.

Sorry everyone I have been looking at the wrong team name on our paper. We arnt Onslaught soz. (Coz I was on this a few days ago and I saw woodies team name!)

I think we changed to Whiplash so were still searching for names.

Sorry!

Vertical or Horizontal?

I still prefer vertical spinners, with the wheels wide apart. Like Hornet 2, Nebelwerfer, Katjuscha, S3, Plofbox 2.

But yes, that is a matter of personal taste. Horizontal disks have 1 big advantage, you can fit a larger diameter disk.
