Hi, This is my first robot.  It's a minisumo robot but as you can see it's more than 10cm long. But when the combat starts it fits into the 10x10 square by lifting … Read more

Making parts

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

Swedish National Robotics Championships 2011

Hi LMR!

 

I thought I'd just inform you of the swedish national championship in robotics. There will be sumo, minisumo and a penthatlon. It will be held at the 9th of april in Gothenburg.

I'm going to participate in the penthatlon with the robot I'm building right now, I haven't posted any pictures of it yet, they'll later today. 

The penthatlon is made up of five parts(duh); maze solving, line following, terrain track, collecting cans and "show off". 

Any fellow LMRers(?) from sweden perhaps would like to meet up and share ideas?

I was busying myself with this robot for the CNRG 2010 competition in Toronto, so I haven't been able to keep up to date on this website.  However I am back now.  … Read more

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.

**UPDATE** Blaster shark has a new title under his belt.  I modified it a little to lose some weight as well.   I noticed I was slacking in the project updating, … Read more

WCRG 2010 Pictures and video

Hello all,

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.

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.
