T'REX robot controller

 

The T'REX robot controller makes controlling robots easy!

The Arduino compatible controller comes pre-programmed with sample code that lets you control it with a supplied Android app, Radio Control or with an external controller via I²C.

Specifications:

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.

UPDATE:  6 Oct, 2013

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)-

Arduino Robotics Reference Manual for School

G'day again all.

As some of you are aware I volunteer every Friday at a local high school to teach a robotics class. These lessons have been going for 6 months now and we have covered quite a lot. I have made a few robots along the way to help teach the concepts (Ben and James) of robotics, allowing the kids to build these robots and program them.

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

Avoid walls and obstacles.

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):

This is WhiteBOB, my member of the BOB family. Because I have no access to a 3D-printer this robot is build from polystyrene sheets (3 and 1mm) and a piece of PVC corner strip.

Sneak preview of T'REX robot tank chassis prototype

 

Inspired by the Rip Saw tank, I have designed a new robot chassis called the T'REX tank chassis. I finally received all the parts for the prototype chassis. The entire chassis including gearboxes and tracks are all metal. The tracks have been anodized a gun metal grey colour.

Arduino Robot Review

Here at Banana Robotics, we're very lucky to have a sneak peak at the Arduino Robot. It's about 7 inches in diameter and features two separate Arduino microcontroller boards. The upper deck is the Control Board and the lower deck is the Motor Board. Each board has TinkerKit type connectors for expansion. The two boards talk to each other via a serial port.
