Cal Games is a COMMUNITY event. We NEED EVERYONE in the Bay Area FIRST community to join the Cal Games Planning Committee to help put the competition together over the course of the summer! The Cal Games Planning Committee is open for all to join, whether you are a student or an adult. So think about what kind of event you want, what side events, what awards, what speakers, what displays, and come speak your mind at the summer meetings!


Frequently Asked Questions:

Q: What if we mail our registration before August 1 for a Tier 3 spot?
A: If received PRIOR to August 1, it will still only be dated August 1, Midnight. If several are sent in early, they will all have same date and time.

Q: What if dates/postmarks are the same and not enough slots?
A: If Tier 3 registration fills the balance of those slots, then a lottery will ensue and others can go on a waiting list. CalGames 2008 will only have 30 slots.

Q: Why did WRRF raise the registration fee to $450?
A: Gas prices are high, as you know. Trucks used for the event use gas. That is one reason. Also, the field this year looks to be more expensive to build and set-up, thus the budget is higher.

Q: When does the $100 Volunteer Support Deposit fee get refunded?
A: The support deposit will be refunded after CalGames 2008 if that team shows up for their assigned volunteer spot.

Q: What happens if not enough teams sign up?
A: In the unlikely event that insufficient teams pay by September 15, 2008, the event will be canceled unless enough teams completely register by September 2 and registration fees will be refunded.

Q: Will a liability waiver be required for each student, mentor, adult, parent, etc. from a team?
A: WRRF liability waiver will need to be completed by every team member attending, similar to that done for any FIRST competition. These will be in each team’s registration packet send several weeks before the competition.

If that is the case, Tier 2 "Rookie" teams would have to build an entirely new robot. Or, they would have to rebuild their Overdrive robot into something completely new/different. I don't want to be a wet blanket, but that doesn't sound like a great idea. But then again, that is just my opinion. :o

It will be a re-play of the 2008 game "Overdrive"

Sorry about the mistyping.

Sorry folks, the typo was in my original post to WRRF community. It is the 2008 game. See the .PDF (corrected) I posted for WRRF.

Enjoy!

Who's excited for tomorrow?! :)

When I left, lots of teams hadn't made it in yet.

Re: Cal Games 2008
 
There are a couple of teams that are expected to show up
early in the morning. We did quite a few practice matches
to test the field before closing up shop this evening.
Everything appears to be ready to go.

See you there!

Re: Cal Games 2008
 
Another awesome WRRF event! Congratulations to all who competed, and thank you to BAE and all the volunteers!

Champions:
604, 100, 971

Finalists:
980, 2473, 115

846 won two design awards.

692 won the other judges award (I believe)

1351 won an award for hosting the event (they did a great job)

I didn't catch the name of the volunteer of the year.




Our team learned a great deal from this event.

Before the competition we decide to redesign our drive train to make it faster and more powerful. We decided to essentially hack our super shifters and turn them into "super non-shifters." We removed most of the excess gears and replaced the aluminum side plates with ABS plastic. This left us enough weight to add the two FP motors.

The result? Dramatically more power and speed, and 2 pounds lighter :eek:

All was well and good at Cal Games until the finals, when we had to play four matches back to back.

The new side panels were unable to dissipate the heat and our breakers tripped repeatedly, causing our robot to be jerky and slow. :( We even tried to use ice-packs to keep things cool... But we never really solved the problem.

Nonetheless it was a great learning experience, and something we will be accounting for in the future.

Perhaps AM should take note not to use plastic on the motor-side of their tyrannies anymore ;)

ummm.
about the awards that were won, you forgot one.

We won an award for their performance during hybrid <we knock a ball off of the overpass>

Just to clarify, Ken Mitchell has been an extraordinary volunteer ever since he became a part of WRRF. Whenever we need something done, Ken is always the first one to step up and take care of it, and this year he took care of the Sundail system, the A/V & computer setup at the scoring table, took the lead of team queuing, and was one of the first ones to show up to direct setup and tear down.

Great job Ken!


Then to clarify the Hybrid period awards,
the Finalist for the CalGames Hybrid Period Challenge went to Team 846,
and the Champion for the CalGames Hybrid Period Challenge went to Team 701.

The Highest Seeded Rookie Award also went to team 2551.


By the way, I would love to see any pictures of the event uploaded. ;)

This is pretty common when you use the FP's with just two CIM's. We had this problem often in 2006. We burned up probably 10-12 FP's with a similar setup. If you don't have a heatsink/fan blasting the motors it's pretty much guaranteed to happen if you're using them under a lot of load.

Suprisingly, it was the CIM's that got hot, not the FP's... The FP's stayed nice and cool (we used heat sinks).

We never had this issue of over heating CIM's with our aluminum plates, and we had only half the motors in the drive :ahh:.

Congrats to the WRRF for yet another terrific Cal Games. Ryan Epperson did an outstanding job as Cal Games manager, as did the awesome group of volunteers who supported the event. We totally enjoyed the energy at the venue, especially in the elimination rounds.

We're looking forward to coming back and maybe winning two matches in next year's finals!;)

Re: Cal Games 2008
 
Thank you David, We could not have done it without the field that you brought up from LA. That helped make CalGames such a success!

Thank you to all the teams that came and volunteered, we were packed up and out of Mitty in under 2 hours! We could not have done it with out all of the students and Mentors. You guys help CalGames run smoothly!

Thank you!

CalGames 2008 Manager

I really don't understand the issue that was happening, can you provide more details about your system?

From what I'm assuming, your gearbox is a Super shifter with one pair of the shifting gears removed, with custom plastic plates, a single small CIM and a FP into an AM planetary (with a heatsink).

Breakers were being tripped, and the CIMs were hot are the symptoms you claim?

I also don't understand how your CIMs stayed cool when there was only a single on each side; Every drive I've been involved with since 05 had atleast two CIMs (and in once case a FP in additon) and they always became really hot after use.

Yes.

We brought ice-packs to the games expecting the FPs to over-heat. We were very cautious to keep their temp down. We never worried about the CIMs until the finals matches :ahh:

Keep in mind that our old trannies had aluminum side plates.

As Mr. Baker explained to me, shifting did a lot to lighten the load on the CIM's. Running at our slow-speed of 6 fps didn't draw a lot of current. We only used the high speed down the straight-aways.

Our new transmissions were geared slightly higher to 11 fps, which probably drew more amps when turning.

We also had new drivers at CalGames, who might have been pushing our robot harder than I ever did...
