Let's Make Robots!


Introducing myself

Hello everyone,
My name is Albert and I'm from the Netherlands.
A very capable Robot, that can be remote controlled or rely on numerous sensors to be autonomous.

2 wheel self balancing robot using arduino and IMU6050

I want to build a two wheel self balancing robot using Arduino and the IMU6050. After a few weeks looking around robot and arduino forums, without much luck, I thought perhaps users might share their experiences, ideas and code on this forum.

For starters, I built the platform out of 5mm plywood, using the following componnents

2x Tamiya 70168 Double Gearbox Kits
2x  Pololu Wheel 90x10mm
1x L298N Dual H Bridge motor driver
1x Arduino Uno
1x IMU6050 board
1x bluetooth module

Electronics for homemade CNC machine

Hi all!

I plan to build CNC machine. I have already found 3 unipolar stepper motor from old printer.

Type of CNC will be like http://reprap.org/wiki/WolfStrap-English#WolfStrap-Fran.C3.A7ais

For electronic part I have two options:

How do you program a screen with Arduino?

How do you program a tv screen? I want to do it with arduino, so I can put it on one of my current robots, an entertaining stationary robot head on my desk. I provided some pics of the screen I'm using. Please comment.


[ARDUINO] Spider dagu burn

hello everyone. 

I recently acquired a Dagu Spider malheureusment but I have a little problem that I would like to expose you BEFORE testing it myself. Because Dagu has cost quite expensive for my small ways! And my first test has not been very conclusive. So i have questions :

I'm using :

- 3 servos connected (D13, D12, D11). 2 Tower Pro MG995 and 1 Micro Servo 9g.

- 6 alkaline batteries 1.5 V LR6 - AA


.... the board heating  and no LED lights. Is this normal?

.... Am i using a bad batteries ?

Wild Thumper Robot Controller: getting started autonomously

I'm a beginner in coding and I'm trying my best to work with the sample code, but now I've come to an impass. Can someone tell me what I'm doing wrong with this? http://pastebin.com/cFscTs6d 

I'm getting the error:

Wild_Thumper_Controller_Prototype.ino: In function 'void I2Cmode()':

Wild_Thumper_Controller_Prototype:357: error: a function-definition is not allowed here before '{' token

Using Pololu's #2130 to control two motors

I'm going to be making a simple 2 wheel robot that can avoid obstacles using a Ping sensor. I will be using an arduino uno, a breadboard, the motor driver, and two dc motors with wheels. I found Pololu's #2130 after someone recommended it. It can control two motors and it connects to a breadboard. How would I program this like I program an Arduino.

Arduino nano setup

I was wondering if I could hook up an arduino nano to a micro breadboard. 3 servos and a Ping sensor would be connected via jumper wires to the breadboard. Can this be done? How though? Thanks!

Wild Thumper Controller Compilling Issue


I recently purchased a Wild Thumper Controller for my Wild Thumper . I tried to modify the controller software to use a LiPO battery and to test my ability to compile the code. Unfortunately I ran into several problems. The Fist was:

I was using the 1.0.5 Arduino Compiler:

         The Compilers are not backwards compatible and you must use the 0.0.18 IDE. (Thanks Russell Cameron)

Turning too much

So the robot I built is a two-wheeler, well three-wheeler, its got one small rotating wheel on the back. It uses an ultrasonic sensor to measure distance. My problem is that I'm having hard time making him go straight. Neither of the two DC motor driven wheels is more powerful than the other, they rotate at the same speed, and I programed them to do so.

Arduino Sketches are "Evolving" for Official Robot.

When programming my "Official Arduino Robot" I have noticed that routines that would work on my previous robots need modification (this is under Arduino Sketch ver 1.05.)


PROJECT CONTINUED! So I found a motor from a toy. Works fine. The same speed as the other. But I still have the problem with the whole robot turning. I'll post a … Read more
