Bring On The Canucks!

Filed under: Hockey — Bob @ 8:29 pm

hockey.jpgI’m usually regarded as a hockey fan by friends and family. Eileen and I had tickets to the Canucks games last season. All through the playoffs I’d dash out of work early to catch games when I could. I feverishly followed the standings all the way to the final round of the playoffs and watched Edmonton battle back from certain disaster. It was tremendously exciting, especially Game 7 where it really could have gone either way – at least that is what the Edmonton fans are telling themselves even today. :^)

But then the Stanley Cup was won, and I was done with hockey. It was a combination of hockey overload plus the fact that it was Edmonton rather than the Canucks I was watching make a tremendous run for the Stanley Cup. I really was tired of hockey. We got mail from the Canucks organization inviting us to spend a lot of money on tickets for next year. I was really close to saying “nah, we’ll catch a game or two and watch them on TV and see what happens”. I was tired of hockey, especially the ever-the-losers Canucks.

Then, a few things transpired. First was our new coach Alain Vigneault (not a surprising choice). More significantly, Todd Bertuzzi gets traded in return for Roberto Luongo – a fantastic goalie. I thought we paid more than we got but we got rid of Bertuzzi and picked up the most promising young goalie in the league today, so maybe it works out ok after all. The latest rumors say that our other goalie Dan Cloutier is also up for trade; undoubtably there is more in the works too.

The team will look very different next year. I think its a shame we traded away Brian Allen and Alex Auld and we might not be able to re-sign Ed Jovanaski but overall I’m happy that the core of the team is being rebuilt.

We signed up for tickets again next season and I’m eagerly awaiting the start of the new season. Maybe they could start a little early this year?

New Pictures Uploaded

Filed under: Machining,Robots — Bob @ 9:30 pm

I uploaded some photos of my new minisumo project (tentatively called The Thin Man) here, and a photo of my latest circuit board project here. I haven’t had much time to get the software written for the circuit board yet, but it appears to be working as designed with a couple of quick tests.

New Robot Project Started

Filed under: Machining,Robots — Bob @ 8:55 pm

Ever since my trip to Calgary for the Western Canadian Robot Games I’ve been thinking about a new mini sumo robot that would be competitive with the best robots I’ve seen. My current top-contender Velox really hasn’t been very competitive for quite a while now but I wasn’t sure I really wanted to build another mini sumo. After all, I’ve also got a few other projects on the go already…

Last weekend I finally decided to start building. My new design puts emphasis on a low profile and speed. My goal is to make a thin wedge that is less than 3/4″ tall and moves at 5 inches per second. It’s going to be a very challenging project. I’m starting with a block of aluminum that is a little over 10cm square and 3/4″ thick, and I’ll cut and mill away most of it, incorporating the motor mounts, front scoop, PCB mounts, etc. into one frame. I’m also planning to design my own PCB that puts all the electronics (including sensors) onto a single board.

The machining should be complete in two weeks or so (mostly evenings and some time on the weekends) then I’ll start on the PCB design. I plan to compete at Robothon in Seattle in the first week of October so there is no time to spare – especially since I need time to prepare my other robots too!

Trip to the Flat Land

Filed under: Books,Commentary,Holidays — Bob @ 7:59 pm

Eileen and I spent the last 10 days in the mid-West of the USA visiting relatives. My mom lives in Michigan while Eileen’s folks live in Indiana and has aunts & uncles in Ohio. We flew out a week ago last Friday on United Airlines from Vancouver to Detroit via Denver. United has figured out that we’d pay a bit more money to sit in more comfortable seats. They’ve invented a new section titled Economy Plus. The seats themselves are the same as the rest of the plane but you get more leg-room for $44 per seat, each flight. The trick is to check-in early – you can only purchase this “upgrade” when you get your boarding pass (we did it at the electronic check-in machines) otherwise you take your chances. Glad to see the North American airlines starting to find interesting ways to improve the travel experience as well as improve their bottom line. British Airways has been doing this sort of thing for years with good success.

The USA looks pretty much the same as I remember, but the complaints are new. We heard plenty about the outrageous price of gasoline and also about how illegal immigrants were ruining the country. Oh my. The gasoline thing is especially funny because nearly two-thirds of the cars on the road are SUVs (we counted). Eileen says the number of SUVs purchased each year in the USA continues to increase, although I was unable to find a reference that supported or denied that claim. Gasoline was something like US$2.80 per gallon, which would equate to CDN$0.82 per litre. For comparison, here in Vancouver its CDN$1.20 per litre, or about US$4.11 per gallon. We laughed so hard we snorted.

The immigrant thing was more sad than funny, its a hot-button issue that most people don’t really think too carefully about. The economy of the USA is dependent on the immigrant work force in ways that probably can’t even be predicted. For example, immigrant workers keep the cost of farm labor low, thus making it possible for domestic farms to remain competitive with imports. Food costs remain low and many people (illegal immigrants as well as citizens) are employed. The low cost of food means the general cost of living is lower for everyone. Low cost of living means higher discretionary income which is usually spent on luxury goods which further fuels economic growth. If you eliminate the low-cost labor on those farms, will it negatively effect the entire economy? Maybe. I don’t really know, and I don’t think its entirely predictable.

Don’t misunderstand me, I don’t think illegal immigrants are preferrable to legal immigrants. It’s just that the current situation is complicated and perhaps making hasty decisions and drastic changes isn’t wise.

I’ve been reading Collapse by Jared Diamond. The subtitle is How Societies Choose to Fail or Succeed and it discusses (with incredible detail) a number of factors that can lead to a particular society such as Easter Island or the Norse in Greenland to completely fail. Its well written and very interesting. This book talks about how societies become entangled in their own history, location, habits, and neighbors in interesting ways that sometimes turns out quite bad. And sometimes it works out ok, but it is very hard to predict the outcome ahead of time with any certainity. I think about the current situation regarding immigration in the USA in similar terms.

The other sad part of the immigration debate is that people seem generally unaware of the need for immigration in order to continue the existing standard of living for retired people. By 2011 there will be more people retired than working. The number of people retiring each year will continue to rise, leading to a significant problem where the taxes paid by those still working will be insufficient to pay for those who aren’t. The existing population in the USA and Canada (and probably other places) isn’t increasing fast enough to offset those who are retiring, and without working immigrants to make up the difference the government sponsered retirement funds will collapse.

The trip wasn’t completely doom-and-gloom however. My sister came to my mom’s house with her two-year-old daughter to visit from North Carolina. I hadn’t met her daughter before so that was really great. My mom is doing well too, and Eileen’s folks are getting along just fine. We also caught up with some friends and spent a couple of hours walking around the campus of Michigan State University where Eileen and I met. The campus there is really beautiful and the day we went was bright, very sunny and warm.

05-25-06_1903.jpgThe other thing we noticed – the place is flat by comparison to Vancouver. Some parts are so flat you can virtually see into next week. This terrain leads to tremendous wind storms and quick changes in weather. We sat on the back deck of her aunt’s house and watched a thunderstorm come in over the horizon. Within minutes the wind was whipping around and the rain was pouring down in bucketfuls. It rained and thundered for a half-hour or so then stopped. I grabbed a picture with my phone, it seems to be clear enough to demonstrate all points.

Tomorrow we’ll go back to the office and try to catch up from being away.

Western Canadian Robot Games

Filed under: Robots — Bob @ 8:16 pm

I spent last Saturday at the Western Canadian Robot Games in Calgary, Alberta. This was the 16th annual event but I had never been to it before. My friend Dave Hylands has been going every year for I think the last four or five years and always suggested I attend. He was right, it was a lot of fun.

I took some pictures (not great quality, but whatever). Find them here along with a short description for each one. The crowd was reportedly smaller this year than last but it was still well attended. The setup was very professional and the hosts were well organized.

I entered three robots: a linefollower, a minisumo and my walking metal hexapod. Eileen says it looks like a bug so I call it Metal Insect – got any better suggestions, leave me a comment. My linefollower did ok but not great. My minisumo didn’t do much better, its really starting to show its age against the tiny fast wedge robots. But the Metal Insect did catch quite a few eyes and was awarded Coolest Robot by the judges. I really was very proud as I spent quite a bit of time giving this robot some personality.

An annual tradition at the WCRG is the Solarbotic’s Barbaque afterwards. Dave Hrynkiw and the rest of the Solarbotics crew host a big dinner every year. It was great to spend another few hours talking about robots while quaffing beers and chowing down. I got to meet Dan Gates in person- he joined Solarbotics recently and is already busy creating new designs for them.

I’m definitely going back next year, I had a great time. I’m already planning a new minisumo robot, and I hope to have my Robomagellan robot working.
