Let's Make Robots!


Awesome website!

Yes, LMR IS an awesome website, but some may also be interested in one I found.

See: http://www.helloapps.com/index.html  All the files and tutorials for getting into MRDS.

"Microsoft Robotics Develpement Studio" (Covering both versions 3 and 4,)

This website covers all aspects of robot system modeling including mesh design and science.

(I have a book on MRDS, but trust me, this website is easy compared to the book.)

When you get a chance, check it out.




A little robots journey - Epilog

Finally EL2ISA2 aka Artoo is back from his journey. Like in the vaste of the universe he was travelling thousands of lightyears kilometers/miles throught China: Following up the previous travel reports: Tatooine, here and here. Here are some of the pictures and comments of his adventure.

Bluetooth and XBEE

Hi, I am working on a project that includes contolling a robot wirelessly though visual basic 2010. And I was researching and found that if you use an xbee it is the same code as when using a usb cord. But i want to use bluetooth instead. And I was wondering if the code is the same when using bluetooth (like the xbee). I assume that it is the same because it is a form of RF. But I need to know from LMR if it is the same code with Bluetooth or is it different.


Robot Teaches Itself How To Walk.

Very interesting work of making a robot learn about itself using gyro feedback and programming in rules based around this.

Looks like it would be a quicker way to program robots to do complex tasks perhaps...

Artoo, I told you that's a dead end...

Annual Online LMRobo-games!!!

What if somebody makes an annual robo-games for LMR members that is held online? just like Robotgrrl's robot party but with games and stuff e.g. online robot racing, online robot chess games(for those who do have chess playing robots, and connect them o the internet and play with other people), robot catwalk, coolest robot of the year...etc. and the prizes would be certificates that can be sent and print by the winner, or stuff that i don't know.

so, anyone interested in this kind of concept?

TITAN robot

This project is HUGE. Lets start form the begining, I am a university student and for my final project I wanted to do a big robot, that is untill I found out that the university picks a group of projects and you choose one, so I've decided to make it anyway. 

UPDATE: New post has me controlling servos with my arms!!! check it out at my blog

Robot position localization using Monte Carlo filter

I am taking Udacity's "Programming a robotic car" free online class and I think it is a great resource for all robot builders! Since the beginning I have seen a lot of question about the way to try algorithms we are learning with real robotic vehicles.

#define INA_2   10   //This is the left forward control of the robot, I defined each pwm pin that is connected to the arduino

#define INB_2   11   //This is the left backward control of the motor, e.g set this high and INB_1 high and others low you will do a reverse

#define INA_1  5    //This is the right forward control of the motor

Driving a motor with solar cells (without a solar engine)

What I want to do is this: I have a basic bicore hooked up to a vibration motor.  He kind of flops around, but it isn't totally random.  Anyway, I was wondering how I could power him with some solar cells that I have without using a solar engine.  If that's possible, I would really like to hear some ideas.

infrared sensors

I've got two sets of phototransistors and infrared emitters put together to make two IR distance sensors. They are both connected in the same way, both powered by my Arduino Uno, both with the same resistor, etc. But when I check the values I'm getting from them, one of them ranges from about 980 - 1010, with the higher value closest to the sensor. The other, however, goes from about 350 - 570, with the higher value the furthest from the sensor.

It uses a Parallax Basic Stamp and four servo motors. It will use a SOMO 14-D to read the recipes aloud. The buttons are going to be used to control the reading of … Read more

How do you connect a SRF005 to an Arduino MEGA 1280

I need help on connecting a srf005 (the blue one) to an Arduino MEGA 1280

You can use this image as a guide.

I want the connection for the srf005 using only three pins. :) (The one where you connect the mode pin to ground)

I have been inspired to make an analog neural network robot after seeing phoenix. My robot is called synapse and it will react to its environment. It is nocturnal and it has touch sensor arms and only is active at night. I will update you a soon as i can.
