Wavefront Algorithm Mapping

Hi, LMRians. I've been reading up on this Wavefront Algorithm Navigation and I understand bits and pieces of it, but not everything. I'm trying to learn up on it so I can use it in my next robot : Project 4L-FRED (Alfred), a butler robot. The robot is suppose to navigate around the house from the dining area to the living room and serve drinks to guests. The robot will have pre-recorded messages like greetings and stuff like asking what drinks the guest would prefer.

Wireless surveilance system..

Hi, all, this is a bit of a random night post, but, i need your help...i need a cheap way to make a surveilance system.. 

I have a CCTV camera module that looks like that, and no, it's not wireless, doesn't have a receiver. It only has Audio/Video cables and a power cable. Is there a cheap way to make this work using bluetooth? I only need to spy from 5 meters away. Btw, i want to be able to receive the video from my laptop. 

FREE Atmel/AVR chips of your choice!

Okay, i know some of you think i'm mad, but if you have an Arduino at home, and want to buy some blank AVR chips on Ebay and bootloader/program them, DON'T! Instead, why not get them totally FREE from the manufacturer themselves? All you need is to do sign up at the Manucfaturer : Atmel website and you are good to go.

TOP SECRET [For your EYES only]

 In advance, i'd like to apologise for having some Upper-case letters in the Title, hope it isn't bothersome. 

Teaches how to upload picaxe code to it's board. ; )
I'm just going to post a quick tutorial on how to upload PICAXE code to the selected PICAXE board you have. This tip is dedicated to David Chetrit, who has had some … Read more

Experimental RC Robotic Hand

Introducing my Experimental RC Robotic Hand. I'm going to use it for a robot that I will use to take on Ro-bot-X's "Search And Rescue" Challenge. It's purpose is to get a hold on the drink, obviously. This is only Version 0.2, I'm am currently building a lighter and easier to use grabber to replace the heavier hand that is attached to the winch motor.  More updates soon.

Why won't it vark?

I've made a development bot named Arcee as some of you know, now i've added an AmandaLDR to it for obstacle avoiding.The LEDs on the sensor are very bright and blue in colour. The bot won't use a servo to pan the sensor, it'll simply rotate itself.

The problem is, I don't think it's working. But the sensor works, oddly enough. It can turn an LED on at a threshold. But once implemented into an obstacle avoidance code it dosen't seem to work.

The code is attached below.

My first Arduino SHR

 

Hello LMRians. I'm now super exited as most of my robot parts have finally arrived!

These parts are going to be used for my first SHR. The brain, if you would like to know, is an Arduino-based microcontroller.

It is indeed the Ubotino Controller V3 and measures at a mouth-gaping (for me that is) 5 x 5 cm!

This board can be bought by our well known Ro-Bot-X at his online shop : http://robotxdesigns.ca/

Here are some very bad pictures of the parts :
