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

Fast vision sensor for Arduino

Reverse pendulam using Rpi,Arduino and additional 0.75kg - which rover 5 chassis to buy



i am trying to built a autonomous car ( which can also be controlled by wifi) using DAGU rover-5 chasis , dagu 4 channel motor driver , raspberry pi (for wifi and camera) and arduino uno. i also like to use the same platform for inverted pendulam project using MPU6050 which is my next stage target , so the car needs to be very swift or agile to maintain the balance and change the direction.

Code Post - Interfacing Arduino and Python

This is something I've done by hand at least ten times and always seem to lose it so I've decided to post it here. It is an easy way to debug and test stuff will developing software for the Arduino (or any Microcontroller really). There is a python code that sends string messages to the arduino over serial based on which arrow key on your keyboard is pressed. There is also an Arduino code that listens for these messages, then repeats the message back to the PC to make sure it went through.

Arduino Code Troubleshooting - VEX Transmitter / Receiver

I'm trying to read the signals sent from the VEX transmitter to the VEX receiver through my Arduino Mega. I started with this code and then made some modifications to visualize the outputs.

Ok, I have been too lazy to update this as this was done a month or so ago. I hereby declare this project complete. It is now bigger and better! Below are some photos and a video of the completed matrix and driver board(click any picture for a larger view)-

how to implement the Wavefront algorithm

I am thinking of creating a robot that can navigate using a map it is controlled from p.c and it is having 8 bit controller to do low level task were the PC doing image processing I planned to implement it in a single room where the robot is placed and it (robot and environment) is tracked by a camera from a height or in the ceiling of the room. First the robot need to be mapped, like this http://www.societyofrobots.com/programming_wavefront.shtml

Accurate Indoor Localization using OpenCV, OCR

Just got this pieced together...Robot looks around, recognizes words written on walls and determines compass bearings to each.  Robot then determines what room it is in based on its memory of visual landmarks, and loads a map for the given room.  At this point, the robot calculates its location in the room to within a few inches.  Robot then knows where other features are within the room based on its map (Doors, Windows, Obstacles).  In the video, the robot announces the heading to the door.

It acts as a theremin instrument and avoids obstacles also entertain :)

[SOLVED] Strange compilation error

Hi everybody!

I'm making a little robot using Arduino and it works fine (you can see how it works on the embedded video).

The robot walk alone perfectly but today I tried to use an infrared remote with an infrared receptor to use my robot like an RC car, and I had this error at compilation (I'm using IRremote library):
