The Consistent Winner

TeamTiki Is a little different. Unlike most robot combat teams we are not there to win. Our primary goal is to have fun and put on a good show. Because of this philiosphy TeamTiki doesn’t take home many medals. There has been one trend, our team artist Mike Nagamoto has taken a medal at every RoBoGames hes entered!

The art-bot display was quite killer this year, incorperating NagaMoto’s Mola Mola in coper, Elise’s Tiki Posters and a borrowed sheet of plexiglass.

here is the inscription that accompanied this year’s display:

Michael Yoji Nagamoto, metal sculptor, has transformed salvaged and new metals into sculpture pieces. Sculpture art that has a definite utilitarian twist also graces homes in the Bay Area and beyond. Inspiration comes from more than 35 years of diving off the California coast and Hawaiian Islands. A retired Fire Fighter of 30 years and now Welding Instructor at Laney College brings fire and water together to make “artsy fartsy” . Come to Laney College and take one of our Welding Courses. Learn the Principles and Practices of Welding and then go on to a career in welding or make your own “artsy fartsy” creations.

Mike “Artsy Fartsy” NagaMoto is avalable for commissioned pieces, decorative as well as utilitarian. contact site adminstrator for further details.

The Big Show – RoboGames 2011

Bandsaw and Steel

So It begins. A new year and a new event quickly approaching. Around 3 months till RoboGames 2011.  We are committed to building a 60lb Lw Combat robot, a picture of the prototype;

prototype tire bot

Running gear: pair of Stature gear motors for drive, the electronics box borrowed from the Count, a Michelin tire as armor and a plywood mock frame. With a few hours invested in this test bed we were up and running around the shop. Its squirrely fast, I know it can be dialed back with the right radio. What i’m not sure of, the direct from China radio can be set up for an expo curve.  After consulting the Engrish laden manual it would appear that is not an option.  Maybe the robot can use the Futaba….

In addition to TireBot, which is Scott and Mike’s Bot, I have landed on a concept and theme for the artbot. Or one of the artbots, I would like to produce more than one. I would love to make at least one hockeybot… Ah too many robots not enough time or money.

The Count – Build

Cheap Motors need a home, time to build another showy non-competitive combat robot!

 The end result of Day 1.

Lets take a quick look to see how we got here

Step 1: A blueprint, a plan, a rough sketch, a vauge idea…   Somewhere exists a “not to scale” back of the napkin sketch of how The Count was suposed to go together. Everything looked like it would fit, wheels where the shoulders would go, lots of leg room for a big propane tank, it was perfect.  One of these days I’ll learn solid works… untill then

 

Plywood aided design!

The wood serves as ful scale blueprint, cutting fixture, welding jig, and maybe even a lid.

Here I simply lay the square steel tube over the template and use an angle grinder or hacksaw to miter the tubes.

 

All cut and test assembled

 

  And here you can see TeamMate Miles giving the frame a test fit.

Cheap Motors; cheap for a reason

I love a good deal. But more than the deal is the hunt, garage sales are the best for finding that goldmine. This story takes us to ebay…

There was a pair of WheelChair motors, with wheels, crazy cheap. When they arrived they both worked, but one was much faster than the other.  It wasn’t untill they were mounted up to the frame of the robot that curiosity got the best of me and I  had to find out why one motor was so “clunky”.

Gotta love Cnc, from print to part in moments.

I pulled the motor bolts out, removed the brushes, and the case and endbell came off as one unit.   So did 2 of the magnets…

Just Busted loose, not broken or even chipped. The magnets had clung to the armature, when the motor  reversed direction the magnets would rotate with the laminations till it hit the bolt that runs the length of the motor can. The “Clunk, clunk” noise

You can see the groves worn into the magnet from rubbing on the steel laminations. Tough magnets indeed.

One i’ve prepaired previously. Glued that magnet in yesterday. Couldn’t imagine trying to keep 2 glue soaked self repelling objects in place…

A clamp should hold this well enough till the glue sets up.
