Blaster Shark

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.

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.

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.
