Robogames – The Big Day

Catherine was off on vacation, David had a graduation to attend to in the morning, so that left Raymond, Eric and I to take the blimp and all of our stuff to San Francisco. We woke up super early — about 6:30am — and made it there around 8am (we got a little lost). The warehouse Robogames was hosted in was on a huge dock on the Bay. We were puzzled when we got there. No one was around and all the doors were locked. A couple of other people were standing outside so we asked them what was going on. Turns out we had arrived about an hour early….

Raymond, Eric and I decided to take this time to explore the surrounding area. We walked along the beach and came to a pier overlooking the bay. We were pretty surprised to see people actually swimming in the bay so early in the morning. Just as we were leaving, a group of five or six people wearing swimsuits showed up and informed us they were going to dive off the pier into the ocean. That’s right. You read that correctly.

Eric and Raymond immediately took this as a photo shoot moment and began snapping pictures like mad. I admit I was a little skeptical about these people diving off such a high pier into the middle of the bay at such an early hour with such low temperatures. But they did.

Since it was about time for the doors to open, we decided to head back. We were glad to see that the ceilings were pretty high, meaning that Eric and I would have plenty of flying space. We immediately registered and claimed one of the empty tables. Then Eric and Raymond got started on setting up the airship, making sure the electronics were functioning and filling the blimps with helium. I set up the laptop and ran the presentation on it explaining who we are and what we do, and also put out the fliers that also had information about us.

In less than two hours, we were set to fly. By the time the blimp had reached the ceiling there was a crowd gathered around us. Eric and I circled it around the warehouse a couple of times, even trying to maneuver around the rafters (which was a bad idea, we almost got stuck). Then, we decided to see how long it would take us to fly the perimeter of the warehouse with Raymond timing us. It took us less than three minutes.

Thrilled, we decided to clean up our work area and to turn it into sort of a display. We balanced the lightweight airship on a tripod and stacked our tackle boxes full of supplies underneath it. On the other edge of the table we positioned our promotional materials. Then we cleaned off any stray trash and put away the rest of our supplies under the table.

Then began the waiting.

Best-in-show wasn’t to be judged until later in the afternoon. Raymond and I had other things to take care of back in Fremont, so we took off first. Eric stayed at the warehouse, where David accompanied him later.

At about 2pm, we were judged. Raymond and I called in to check what had happened. We won second place!

By about 5pm, all of the stuff was out of the warehouse and back at Eric’s house. David has the medallion, which has LED lights so that it looks pretty. Eric still has my laptop.

All in all, not bad for a day’s work. Not bad at all.

Robogames, here we come!

It’s Friday, June 12, and tomorrow is our second competition of the year – Robogames. We’ll be heading over to the San Francisco shoreline tomorrow morning to check in. Hopefully, we’ll be there really early, because we’ve got to get in and get set up as soon as the venue opens.

This weekend, we’ll be competing in the Best of Show category for the Junior League, against three other teams and their robots. The Best in Show is Robogames’ judged competition, in which all contestants are judged based on originality, functionality, and aesthetics.

One of the robots we’ll be competing against is CGLF’s Cerebraen, a luggage-carrying Vex robot from north of the Bay that competed in Robofest. Our competition also includes a team from our friends at American High, who are entering their Robomagellan device, Myrmecophaga tridactyla, in the Best of Show category. According to the event registration page, there’s also one more robot: MVMS’s MDJ mysterious Vex Pinger.

We’re preparing Skittles as a light, man-portable reconnaissance airship. It’ll be equipped with a tilting bracket and our 2.4GHz wireless camera from Tech Challenge, to look around, in addition to the usual dual-controller setup. We’re also going to add an array of white and infrared LEDs, to be used in the dark, that will be controlled using a PWM channel.

In the materials we’ve prepared to show the judges, we also talk about a few possible add-ons. We considered the possibility of including speakers and using Skittles as a device for negotiation. We also looked at including a microcontroller (the Java SunSpot looks like a good candidate, being PWM-capable and features accelerometers and gyroscopes), which would open up a whole new world of possibilities to us.

Catherine’s gone to the East Coast, but the rest of the team will be present sometime on Saturday. David’s actually going to be busy in the morning, but he’ll be coming over to cover for us after Raymond and Rebecca head back to Fremont to cover the FIRST Robotics orientation later in the day. Eric, naturally, will be spending the whole day in San Francisco and hopefully getting some great information on sumo, combat, and autonomously guided robots for next year.

In any case, the team will be finishing up work today and preparing all our competition paraphernalia, so wish us luck!
