I’ll give it a try and report back.

ORE tonight

I went to the Ottawa Robotics Enthusiasts meeting tonight.

I brought an Arduino and played around with a sound sensor. I was able to get it to respond to sound by moving a servo wheel. I attached a piece of wire to the wheel to see it moving easier.

Lots of other projects floating around. Even a kite.

We went to Darcy’s to continue our discussion after Algonquin College closed.

At the meeting and the aftersocial I talked up the wooden mirrors in youtube and also the notion of an 3D CNC ice machine.

I nipped by Local Hero’s on the way back. Interesting place. The bartender called me from the parking lot and asked me to help close the front doors and I left.

Arduinos, Wifi, controllers and stuff

computer

I was just looking at the Arduino Mega and other stuff.

To get a controller into something that you can control through the internet (plus it can get information to you) is rather complicated and expensive. Further if you want wifi, then you’re hurting even more.

I’ve been keeping my eyes peeled for small computers computers that are inexpensive that can be mounted into a project.

Dimensions: 16cm x 11.5cm x 2cm
Weight: 261 g
Price: < 200.00 I'm starting to see this as a great option as a robot or artwork controller. What do you think? Has anybody run ubuntu on theirs much yet? I'm supposing you can run with the desktop and then use remote desktop? Or do people just run server and use SSH to get to it?

Ottawa Robotics!

Check out the ORE blog (Ottawa Robotics Enthusiasts).

There are pictures of the “2011 Trinity Firefighting Competition last weekend”.

Ottawa has an awesome robotics community.

Assembling and Packaging

I’ve been looking at different ways of sorting, verifying and packaging things. It’s an incredibly challenging problem.

Seems the best way of picking stuff up is with a vacuum.

What software is being used for pick and place in general? Is it all custom? What about vision?

Kids and Robotics

Some of the guys over at ORE have been talking about (and doing) volunteer work mentoring children with robotic.

I think it’s an important function and I’ll probably help out at some point. I’m still working on some CNC and some other stuff. As soon as that gets to a certain point I’ll add another volunteer activity.

They mentioned this program which looks rather interesting. There is also the First Lego League competition in Ottawa now.

Locomotion

Wheels are cool but take a look at some of these projects. I think there is a need for something that can go over uneven surfaces.

They may have uses in planetary exploration some day. I think most of the explorers used wheels to get around so far.

Then of course there will be other uses such as new land vehicles that can carry equipment. Perhaps fire fighting, bomb threat surveillance or other applications.

Pay special attention to the last video. I think they have something there.

Ottawa Robotics

I joined the Ottawa Robotics group to learn more about robotics, automation, computer control and such. They’re a friendly group that meets about once per month at Algonquin College. We usually go for a brew at Chances-R or Darcy’s pub. This is a great way to meet other robot heads and not only get lots of help from new friends but to cheer on other projects.

Here’s a video to get a feel for the meetup. You can see a cool model helicopter, some mini-sumo robots. People usually bring in a robot project to show off and talk about.

Here are a few pictures from the last meetup. We were offered a tour of some of the CNC robotics at the college.

Increase your social activity and your productivity: Ottawa Modlab (Hackerspace)

Since I undertook the project of making a CNC laser cutter, I expanded my social activities to include Ottawa Modlab. Ottawa Modlab is an open house hosted in the ArtEngine.ca lab. It’s every second Wednesday.

It’s been a great opportunity to meet lots of wonderful and interesting people. It’s been a very enriching experience so far.

My productivity has been much higher because it is inspiring to see other peoples’ projects and participate in the open forum discussing everyones’ challenges. Also, meeting more people with common interests helps with everything from sourcing to problem solving. It triggered my interest in doing many more projects including more artistic things as well and that makes me happier and I am more effective.

I think if you are interested in making things or art you should find your nearest hackerspace! They almost all have an open house night.

Here’s some video from a couple visits to Ottawa ModLab so you can get the feel for the activity. As you can see I have corrupted them with paper airplanes (not to mention Squirrel model airplanes that I’ve handed out to many people).
