Japanese sumo robot!

By , July 24, 2015 6:00 pm

After our competition in Montréal, I was approach to see if I was interested in going to compete to the 2015 All International Robot Sumo Tournament!!!!!!

wait what? Building and going to Japan for a sumo competition! That is insane! Have you seen japanese sumo robot?


Have you seen the speed!! My robots are so slow! I need to re-think, re-design everything!

I need to design a completely new robot. Here are my initial concept. I only place components to have a better idea on the layout. I also added the weight to each of these components to know the weight. I have to be 3Kg maximum.





I bought my gears at jsumo.com  That does help a lot since that is the key part of the entire design. Founding gear is not easy task. Firat Dede is one of the owner and is super friendly. He is helping me out to make sure I have a killer japanese sumo robot. He has already participate at the Japanese competition. He won 4th place at the All International Robot Sumo Tournament.




This is the latest design. The wheel are far appart. The electronic will go at the back. This is still in exploration, has you can see, I have weird bug in my mirror part, one of the pillow block is touching the left wheel…



btw, I invited my friends from Montréal, Charles-Allix, PM and Denis! They are top 3 competitor here in Québec. Charles and PM have already made some prototype of their sumo! Yep!
Denis will help us with the Schematic/PCB design. We are working together and we should have 2 robots for December!


Got plenty of work to do, I will keep you guys updated!

2015 el-mayo sumo robot

By , July 21, 2015 9:04 pm

This year was Robowar 2015 and I won 2nd place with my new sumo robot. I don’t event have a real picture yet… Here are the CAD image.
Has you can see it does not have a front or a back! It can go forward or backward at any time! It makes it very competitive.








I did this because the rules of robowars has change! The robot is place anywhere in the arena! Plus the orientation of the robot was selected at random!! I could be in #3 pointing up while the opponent is in #6 pointing up! So the opponent simply goes in a straight line and beat me!

robowars_arenaAlso new rules gave more points if you stay in the ring after you push the opponents! 2 points!! if you fall with him, you only have 1 points! I did not have white line detection, so I was always falling out! That is why I am second place!




I do have plenty of video and did not have time to edit. Here is nice and short video of the event in general. (The dude in yellow is me) You can also see my robot kick some butt :)


The name of my new robot is el-mayo, the new drug lord after el-chapo. BTW, el-chapo was able to escape from max prison again this month. So he is on the loose!


My new 2014 3kg sumo robot: EL-Chapo

Some of you know that I really love building robot. I learn alot with sumo robot. I have been building 500 gram and 3Kg sumo robot in the pass and learn many things regarding electronics, software and mechanic.

For those who aren’t familiar with sumo robots, those robot are autonomous and find the oponnent to push him out of a ring. The ring is black and has this white boarder. The robot can detect the white border and know that it should back away or else it falls out.

3kg sumo competition

This is my very first sumo robot. That was in 2006. Has you can see, lipo battery where rare. :) My motors and electronics (PIC microcontroller) where on the same power source. During a head to head match, the robot reset due to votlage drop on the 5V! The PIC reset and went into a “wait for press of push button” mode. I learn that you need two separate power supply, one for the electronics and one for the motors. These days, I have a better power supply so I use a single battery.

The winner of the competition told his secret. They told us that the secret is “battery – motor“, simple has that. I then when and made a new robot call Rhino for the 2007 competition. It use a 12$ cordless drill motors.

New wheels because the old blue tear up 1 day before the competition.

The last competition I attended was in 2007. We are in 2014, there is a lot of things that change in  7 years. Exceptionally my skills! I have learn to use Solidworks and when throught University.

Febuary 28, 2014 I get a email of a competitor back in 2007 informing me that there is a sumo competition in 1 month, march 1st. I thought if I could make a complet sumo robot in 4 weeks. I said yes. I did everything in Solidworks first. The first 2 weeks has design iteration, ideas, etc. I knew that I was going to use a 3D printer to print the chassis, so that help a lot for the design. The next 2 weeks was fabrication.  Lucky me, we have a nice workshop at work. I present to you El-Chapo!

I was reading the news and saw this drug lord get caught by police at the end of febuary. I said that is a cool name!

I won first place! I did not even have white line detection.  Here are the highlight of my robot

Here is the complet 75 match

Hey! What’s up!?!!

Here is my latest project in collaboration with a friend in Calgary, Alberta.


Here is the instructables, it for the 3D printer contest! Please vote for me!!

I will be filming a drifting session with a friend with is M3! That will be sick!
Now I need to work on a version for Ken Block !

what about me? Well, I sort of finish school in Dec 2011. I found a pretty sick job in RnD!! I will talk about it later in a other post.

Electric skateboard?

Like you probably know, I was doing a intern this summer. My good friend Rudy, did a intern at this place where they play with electric vehicle and other cool stuff.  Toward the end of his intern he told me that the company was moving so there where throwing stuff out. He send me pictures of what they where getting rid of! After seen the picture I had a OMG face! He told me that he will give me those things if I would trade something. That something is a video of school projet he did back in 2009. He build a musical Tesla coil and we had 4 feet long fluorescent lamp on the desk, connected to nothing, that was lighting up. So yes we did trade and I got what I wanted!

Here it is:

electric skate board

Yes I also got this ZAP electric belt driven scooter. It has inflatable wheels.

electric skateboardIt looks like an Altered electric skate board http://www.alteredelectricskateboards.com/boards.htm. A cheaper version.

electric skateboard motor system

electric skateboard motor system close up size comparaisonIt’s probably a 200 to 300W motor. Or it could be 600W, I am pretty sure it’s 600W.  Here is the china version of it 

electric skateboard motor size comparaison

Like you probably imagine, I already started to make it apart.

It is in a very good shape. The problem is, the remote control. It use a wireless remote control! I don’t have it and Rudy was not able to find it.  No a problem right. I did try some reverse engineering to see if I could directly send signal to the motor controller. Not really. The controller does not receive a simple analog signal. I took the controller apart and saw a microcontroller under the thick black epoxy. I guest it receive serial data from the RF receiver. OR it’s simply broken!
My first idea is to design and build my own electronics using a Wii remote control! It’s a DC motor, should not be that hard!

After some searching, there is a couple of skateboard company
