Regarding Spike Relay Module

Are the Spike Relay Modules allowed to control the window motors?
Besides the air compressor what other motors may the Spike control?
Is there a maximum number of Spikes allowed on the robot?

Re: Regarding Spike Relay Module
1 - Yes.
2 - Under Rule <R55>, any motor other than the CIM motor and Fisher-Price motor may be controlled by either a relay module or a speed controller.
3 - While there is no rule that explicitly addresses this, by our calculations the maximum number of Spikes that can be contained within the NORMAL CONFIGURATION volume/weight constraints is 883. However, it is noted that the budget limitations of Rule <R22> would limit you to no more than 102 Spikes on a single ROBOT.

:ahh: O no only 102!!!!! but our design calls for 103....

Re: GDC at it again!
 

Notice they did not mention anything about all those Spikes being connected to anything....

Re: GDC at it again!
 

We plan to use about 40 of them for ballast.

Re: GDC at it again!
 

yeah we where going to use them to make weight... at .12 lbs they are really heavy for the price and we need all the weight we can get. Now where did that sarcasm emote go.....

Re: GDC at it again!
 

I was planning on building a wedge with ~35 spikes for more loft on the ball.

Don't pop the ball with all those spikes! :ahh:

Re: GDC at it again!
 

Now what about those Vics? And Jags?

Re: GDC at it again!
 

All motors must be run through victors or jags, minus a very few exceptions.

Re: GDC at it again!
 

Not quite correct.

All CIM and FP motors must run on victors or Jags. All other FRC legal motors may be run on spikes.

What you need is the SarcMark!

Re: GDC at it again!
 

Wow, part of me wonders how much time they have on their hands these days!?

Re: GDC at it again!
 

A quick 120 second calculation is all you need to come up with those numbers. The GDC also hasn't taken into account what constitutes a ROBOT. Their numbers are based upon figures that exclude any scheme to put the spikes together. Thus this supposed spike-only robot has no left over money/weight cost for glue, or even a cardboard box. Since that would take too long to get set up on the field (stacking 2 spikes is a pain, let alone 102...), I conjecture a KOP frame + spike-only robot could not pass inspection.

Thus we need to take 1 spike away and use the extra $ for fishing line to tie them all together on a KOP frame. 101 spikes ... time to take stock in IFI!

Re: GDC at it again!
 

The fastener/adhesive exemption <R23-C> could be used here to find a way to cobble them all together.

Re: GDC at it again!
 

Its more the fact of when asked how many spikes are allowed on the robot, they don't come up with a number for all of the motors and pnuematics, they use the weight of the spikes to determine enough needed to fill 120lbs. :)

Everyone else: "OH YES!"
