Let's Make Robots!

Wanted: 12V Batteries

Does anyone know where I can get some 12V rechargeble batteries for robots, I wanted about 2 or 3 for a robot that I plan to build. I would prefer them to be LiPo over the big bulky black ones but I will take what I can get.

 

I will post what I have later on today when I get home.

 

 

 

Fuzzy Logic Controller

Hello Everybody

 

I want to design a Fuzzy logic controller to control two  DC motors of Rover robot  , actually I made a simulation for the controller in matlab/simulink and it worked successfully , now I want to design that controller in real world by using Arduino Uno board , actually I converted the MATLAB Fuzzy Inference System FIS to Arduino C by Converter in the "www.makeproto.com" website .

 

Now for example if one of rules base of fuzzy controller is 

 

New to robotics and need help.

I have never made a single robot before but I have done a fair amount of research and want to create an obstacle avoiding robot! I want to use the arduino uno r3 for the brain! Anyone know of a guide to build in a fairly inexpensive or arround $50 to $60 way sense this will be my first robot?

Which is the best windows PC programming language for the following Robotics project?

Hi,

I am actually very new to the robotics field. I am trying to build an equipment. I was hoping if someone would be able to give me a few advices on the project. 

The current way in which we are planning to connect the hardwares together is as follows

Stepper Motor, RVIT, Foot Switch ----> Arduino ---- > (via USB) PC 

Weighing Machine ----- > (via USB) PC

Camera ----- > (via USB) PC

Speaker ----- > (via USB) PC

Heads up :- Official Hackaday Prize entry - Odds of project landing in quarterfinals (top 50): one in 8.9

Just a heads up to inform everyone that the "Voting" has started on  The Hackaday Prize

Caution:- Dont get caught by the winning prize (its metaphorical) :-


"To Win a trip to space"

That's right, one hardware hacker will get a trip into space as the grand prize. There are incredible top prizes for the other four finalists, and hundreds of other rewards for the most interesting submissions.

Arduino I2C multi-master hardware fault

A couple of my projects recently rely on I2C to connect multiple Arduino compatible controllers. These projects have 3 or more ATmega8A or 328P processors that work as both I2C master and I2C slave.

Need putting on the right path

Hello all, First post so.... nice ta meet cha.

im fairly new to robotics iv built a couple of things in the past but have stuck with primarily mechanical robotics (not sure if thats the right term) rather than ones which require any processor other than my own brain. in all honesty im not even sure if they classify as robots.

My ULTRASONIC (HC SR04) sensor is giving large negative values

I bought it and it was workin gfine with the code and after inserting  it in my project , when i checked it shows large negative values, I tired changing pins , but it doesnt work shows values like 3315,3325 random numbers 

I dont know whether there is a problem with my sensor or my code is wrong. Really worried please help guys.

 


CODE

 

#define trigpin 3

#define echopin 2

void setup()

{

  Serial.begin(9600);

OK, I have just given up making a balancing robot. Ever.

Making a balancing robot - or even dreaming of making one just lost it's appeal.. because I will never make anything like this.,
