Hackerspace and other things

I have been away for a while again :(.  But right now I am sitting at my desk sick as a dog.  I felt I should take this time to update my LMR.  I haven't been able to post my current projects on this site because of this.  Saskatoon TechWorks, a new hackerspace community that has been established.  This means that I will be able to share my knowledge and tools with other like minded individuals.  As an added bonus, I get to use awesome tools as well.

Sumo wheels

Ugh I really have been bad for keeping my stuff up to date but here is something new.

Fingertech Robotics liked my wheels they decided to make some of thier own :D.  This makes it easier for me to and everyone else to build a competitive sumo. 

Back from hiatus

Hello all,

I have returned back from my robot building hiatus.  I've been saving up my money to buy these two things:

Now that I am sufficiently poor, it is back to robots :D.

I have two new ideas and a derivative I am working on.  Ta ta for now

WCRG 2011

The Western Canadian Robot Games just happened last month.  I wasn't able to go but sent my teams robots to run for the mini sumo competition.  We came out second again this year.  Hopefully I can actually attend in person next year.  I am working on some new robots and hope to have them up here soon.  The sumos are currently in Ottawa now for their regional competition.  Enjoy the video :)

Robogames Photos

I have uploaded all my photos to my facebook page.  They should be available for everyone to view.  There are just too many to add manually on this site.  If you have troubles viewing them let me know.

Enjoy.

Picture Time

Just some pictures from when I was getting ready for the games.  They officially start on Friday.  My teammate has gone to the event site for weigh in.  Enjoy

Off to robogames

Sitting here at the airport waiting for my flight. Just cleared security and customer with 4 robots in tote. Will have some pictures soon

SI1120 Sensor working

Developed the code some more to determine which side and how far an object is. The green LEDs signify whether or not either side detects an object. The yellow LEDs signify which side the object is. Lastly the red LED indicates of the object is really close.

Robogames getting closer

The Robogames are coming up pretty soon.  Here is my team almost finished.  You can see Driller Shark on the left after the board and sensor overhaul.  The trusty Blaster Shark on the right.  And the new guy in the middle which still needs some stuff but is coming along.  That is all for now.

SI1120 Sensor

This is a new sensor I'm testing out.  Hopefully will be ready to go into the new sumo soon.

Getting ready for San Francisco

I've been busy lately getting a hacker space set up here in Saskatoon, so I haven't made much progress on my robots.  But now that the RoboGames in San Francisco is coming up, I'm getting my butt in gear.  Here are some of the things I'm working on.  A sensor board and my new sumo.  Blaster shark and Driller shark(currently getting rebuilt) are going as well.  TTFN

Making parts

I spent Thursday night making hubs for new robots.  Enjoy the video.

More Pictures of CNRG 2010

Back from holidays working on lots of stuff in the mean time here are some more pictures from the Robot games, enjoy.

New Parts YAY !!!!!!!!!!

Just got my Shipment of servo motors and brushless motors from Hobbycity.  Lets make robots !!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Canadian National Robotic Games 2010

Hello all,

I had a great time in Toronto for this years Robot games.  I managed to get 2nd place in the masters mini sumo competition with Blaster shark.  I made a new robot called Driller shark which I will post shortly in the robot section.  It didn't do that well, but all in all I had fun.  Here are the pictures.

Ordinary lunch kit?

Huzzah, I have returned from the dead.

After a really long absence, I am back.  I have just returned from a week vacation from Toronto, Canada.  I went out there on Nov 20, 2010 with Blaster Shark and a new sumo, Driller Shark (which I will post soon) to compete in the Canadian National Robot Games.  I placed 2nd with Blaster Shark, and Driller Shark failed hard because of some motor driver issues.  In the mean time while it get my photos and videos in order, enjoy the highlights from the masters mini sumo in the video.

Body - The Making of Blaster Shark (Sumo)

After settling on a layout for how I wanted the robot to look I set about making the body.

Western Canadian Robot Games = Great fun

Hello all,

The Western Canadian Robot Games in Calgary was a great success in Calgary for my new robot.  I will be updating this post with more videos and pics soon and also making a new robot entry for my sumo.  Enjoy the video I found on youtube.  I think Samm is in there too.

PCB - The Making of Blaster Shark (Sumo)

The details of why I picked what parts I picked are covered in the Design blog.  What I am about to describe here is the tools and process I go through to design and etch my own PCB.

Circuit Design

Wheels - The Making of Blaster Shark (Sumo)

After the design of the body and motor mounts I can get an idea of what kind of wheels I need.  The things that are important to consider is the width and diameter.  Both are restricted by the dimensions of the the minisumo.  In my case, since the motor shaft is offset, I can go with a smaller diameter wheel and not worry about the bottom clearance of the robot.  But since the motors are somewhat long, I can't go with a really wide wheel.  With this in mind I figured that a wheel diameter of 40mm and a width of roughly 20mm would suffice.

The Making of Blaster Shark (Sumo)

Hello fellow robot builders,

Its been another while since my last post.  My building mojo has been renewed and I am starting a new sumobot.  The Vulcan Five is on hiatus until I can get the PCB replaced.  This time around I am building a minisumo which will compete in the upcoming Western Canadian Robot Games on May 15th.

Attempt At Making Robot Wheels

Hey guys,

It has been a while since my last post.  The Vulcan Five is not looking too good beacuse of the PCB fiasco.  I'm trying to salvage that situation, but its going slowly.  So unfortunately for this coming up competition it will not be entered.

However recently I have been experimenting with making my own robot wheels for maximum grippage on my sumos.  Here are some puctures of the results.

Dimensional Ultralancer: Vulcan Five PCB

My PCB is finally finished however there is one major problem with it.

Computer Parts Salvaging

My work occasionally has a surplus computer sale, where they get rid of old or non functioning computers.  So I picked up a nonfunctioning one complete with keyboard and mouse for free.computer_salvage_010.jpg

 This is also probably a good time to show you my basement workshop.

The whole setup takes up a corner in the basement next to the central vac.

Dimensional Ultralancer: Vulcan Five - Update 2

Hello all,

 Just an update at where I am at with the Vulcan Five.  I've written and tested some timers to generate the 38KHz output needed to drive the IR LEDs.  The motor controls, digital and Analog I/O all work great.  Now its on to making the PCB.  Low_Profile_Sumo_043.jpg

The first thing I did was cut out some paper to and try to determine a good fitting top cover.

Weekend at WalMart

The new WalMart just opened last week here in Saskatoon.  I decided to visit it which was probably a mistake cause most of my time was spent looking for a parking spot and waiting in line to pay for stuff.  The reason I went was because supposedly this one is the largest one in western Canada.  I probably should have stayed home because I wasn't able to make any progress on my sumo last weekend, however I did find something cool.

Dimensional Ultralancer: Vulcan Five Progress Update

Just a little update on the progress of Vulcan Five.
