Axe - the sumobot

Hello hello!

As you can guess, I am making a new robot, and it is a small sumo!
Features:
- Picaxe 14M
- 2 modified micro servos
- 1 LDR to see the line of the ring
- Sharp IR sensor
- Bottle cap wheels until I make up a better solution (Yes, lol :D)

And when I will receive parts, or get something done, I am going to update this until it is time to post a robot!
Tomorrow (I think) I'm going to post schematics and maybe printed layout ready to make it pcb!

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

Biped robot

Okay. If you know i am building cheap 4-DOF biped.
If you want to know what would it be,it's going to be like EasyBotics Easy Biped :O 

24.11.2011
I got some ideas and i ordered 4x Hextronik HXT900 servos.
Next thing i buy is PCB making things and PicAxe 14M. 
I make chassis when i get some plastic sheets.
But i can tell you some things:
- It has a homemade IR sensor
- And led eyes
- I can modify it easy to walk and avoid obstacles or be a sumo or dance
- I may add an IR receiver to remote control mode 

Competencia Nacional de Robótica Lasalle 2011 (Highlights of the National Competition of Robotics Lasalle)

Here I leave a very few highlights of the Competencia Nacional de Robótica Lasalle, that took place last Saturday.

Sensor seeking.

Let's Make Robots! Hello LMRians! I ordered some parts and i order more in few weeks.

I want to do my own sensor using LDR,IR led and normal leds. And yes, it's going to be something like AmandaLDR but not exactly same.

The sensor is going to my mini sumo, project what i'm working for. It's using Picaxe-08M. What do you think about it?

nanoDuino, sumo and soccer bots

Hi Everyone,

I'm starting with some new projects.

The first one is nanoDuino, an ultrasmall arduino, based on patrickmaccabe's one. This one has all the input and output's pins broken out and the sockets for FTDI and ICSP cables. It is 18,5x20,5 mm:

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?

This is the fully functional test chassis for my Arduino based sumo robot. It will be competing in March, 2011. For the prototype I am using a piece of plywood to … Read more

IR detection

Hi LMR! in need some help with a ir opponent detector. how do you make 38khz signal from a picaxe?

thanks!

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.

Mini Sumo Bot Parts!

Intro

I decided to make a mini sumo robot a few weeks ago instead of doing an obstacle avoider. Turns out that once you think about it, mini sumo bots and obstacle avoiders are pretty much the same! The only changes I would need to make would be to the code. Great! Sumos can also double as line followers. So in short, they're pretty versatile. Here is an image of most of the parts that will go into this sucker.
