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.

Clones TV remote signal, also works as a jammer for the IR signal.
This is a small IR remote capable of copying any 5 buttons of any Remote using IR. I was studying IR signals and this came into my mind. And guess what,it also has … Read more

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:

remote robot JSON setup

Hello,

I wish to get an advice on the remote JSON robot configuration I need to do over TCP/UDP.

I did JSON configuration file - easy exemple:

{ "servo1max"=130, "servo1min"=60, "servo1init"=90, "LED1init"=1 }

I send this file to robot to setup several variables. Several setup files are possible for one robot and I choose what I send to robot without any need to upload the code to robot.

Car alarm remote control repurposing

A while ago, I got hold of a car alarm unit and its two remote control fobs. When i hooked it up to 12V I realized that it didn’t  work, not responding to any of the commands from the two fobs even though their batteries were OK. Naturally, I opened up the unit to start harvesting parts and noticed the RF module within (the one that sticks out perpendicularly) and I figured it shouldn’t be too hard to use the module with an Arduino.

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.

my very First bot - eYandron1

My very first encounter with electronics - a very simple manually controlled robot. The main brain controlling it is a Attiny2313 + a motor driver board based on TIP122 transistors. At the time when I built this, I had no idea about a chip called L293D!

Building a Universal RF Remote - Questions

More Recent UPDATE: the competed remote can be found here. Thanks to fritsl and rik for their respective helpfulness.

UPDATE: Attached (and blurrily pictured below) is my schematic that i think will work for this remote. Yes I drew it in paint, Yes it took too long:

*The "To Breadboard" leads are included so that the remote may also serve as a portable power supply.

 

 

 

Some questions from a beginner.

Hi Everyone,

First, thanks for taking the time to read the forum and answer questions from new guys. I know it's sometimes a pretty thankless task, despite being very time consuming!

 The site looks like an excellent resource, and when I have the time I shall read it more thoroughly. In the meantime I have some quite simple questions about a robot that I'd like to build.

This is a walkthrough on how to make a simple IR controller. It is relatively cheap and easy to make. Programming is simple since the picaxe basic already has … Read more
