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:

Control Blender3D objects remotely

I just made a very simple example using Zeroc's Ice which illustrates how to control Blender objects remotely using Ice. Since Blender can run Python scripts, the idea is to write Ice server which can modify certain object properties (for example location). Corresponding client application can remotely invoke server methods and control objects remotely. Sources are available on GitHub. The first video illustrates how it works.

rover 5 w dagu 4 channel motor control hardware problem?

I am running the dagu Rover 5 (4 motor/4 encoder verion) using a Mega2560 and the Dagu 4 channel motor control.  This is my first attempt at a robot, but do have some experience using several models of Arduinos and motor controllers. 

The code I used is from this first message (by Nick Gammon) and wired exactly the same: http://forum.arduino.cc/index.php?topic=82618.0

PICAXE INFRA-RED REMOTE CONTROL

So i did everything as on this guide

http://www.picaxe.com/docs/axe040.pdf

But it's not working, I think the code is wrong? Can you help me ^^

I use picaxe 28x1

Thank you <3

Testing the wheeled version

As announced in our previous post, we are working on wheeled version of our robot. Tires and shaft adapters are arrived today and we mount them to conduct first test drive. Here are some photos:

Now has video of the robot playing a game and I've attached the code used in the video. You can run this on an Arduino even if you don't have the robot as the game … Read more

The new "Shark" model of our robot

Last year we spend considerable amount of time building the new version of our robotics vehicle. Here is the result - the small tracked vehicle which might be intereresting for researchers in robotcs, AI, computer vision as well as for DIY enthusiasts. All the model, assembling instructions and software are open source.

Making Smart robot

Hi all,

My plans are as follow: I want to make my RC car into fully automated version.

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.

How do I set up a RC control system. Cheep.

I am going to try to make a small cheep telepresence bot using a board of education and an Ipod touch (for the actual chatting) and I was wondering how I should control it. I am trying not to use a another microprocessor.    

How to build BeagleBoard based WiFi robot

Some time ago I have announced my remotely (over the Internet) controlled robot. However, there were not too much documentation and details. So with this post I would like to announce the availability of more detailed project documentation and make brief overview of some interesting aspects of the project. The whole available documentation could be found on the project Wiki.

Real-time enough? About PWMs and shaky servos

We are currently working on the next incarnation of our software and hardware platform for vehicles controlled over the Internet. Among others, we decide to investigate the way to control our robot without micro-controllers. In fact, BeagleBoard has a lot of GPIOs available. In addition, three hardware PWM generators and I2C bus should be enough at least to control the tank with camera, compass, GPS, and sonar.

Drive around, stream video back to the driver.

Bluetooth control from your Android phone or tablet

Hello, I am the author of Mintoris Basic for Android phones and tablets.  I recently added Bluetooth serial communications to the language with the intention of making it very easy to communicate and control robots.

Here is a short example program in Mintoris Basic which connects to a device then transmits data from the phones accelerometer.  So as you tilt the phone or tablet in any direction, the amount of tilt is sent to the Bluetooth device.

dim a$(0)
dim c(4)

' Get a string array of all the paired Bluetooth devices

a$()=BTGetPaired$()

Controlling motor speed with 293 without a POT

This is my first step to robotics. In this project all i did was use an arduino with L293D to control the motor speed without a potentiometer. this was actually an assignment / a small test given to me by CtC (chris the carpenter). the motor is suppose to speed up and down with a delay. 

"stop - ramp up - hold - ramp down - stop"

LMR series of PCB's

I think that LMR should have its own series of circuit boards, with the designs open source for all LMR'ians to use. Heres a couple ideas for PCB's:

Pololu RP5 motor

Hi there, I have recently bought a RP5 chassis from pololu, this chassis is holding 2 brushed DC motors (6V) and I have some questions: first of all; how can I control it? I mean, do i need to control it by PWM or is just 5v or 0v?

second, I built a little pcb with a L293D to protect the controller (Arduino) from reverse current, is this ok? 

Servo time/speed and position control (using an Arduino)

Is there a way to control servo position and speed at the same time? ex: you want to build a biped but you don't want the movements to be jerky.

thanks

Remote 3 Axis Camera Head with motion control

I`ve been wanting to build a mid size remote controlled camera head that has 3 axis and can be computer controlled and repeat its motion. I have a few RC helicopters that we build very basic 2 axis heads on, that work with servos and have a gyro to keep level.

The idea would be for it to rotate at about 300 degrees per second and to be able to feater in and out the motin for it to be smooth. I would also like to try to put some gyros on it, to stabilize it if it is free swinging on the back of a car or helicopter.
