LDR vs Ir Phototransistor

Hi  Everyone

I'm doing research for my first bot from scratch. I was hoping someone could point me to a good source of info on the advatages/disavantages of using LED & LDR vs Ir with Phototransistor for proximity sensors.

My basic goal for them is to have an edge detector in each corner and a line following array. I thought the LDRs would a simple and cheap approach but was surprised to see how cheap this Ir LED & Phototrasistor set was.

ATTiny programming

I saw this link about programming ATTiny:

http://hlt.media.mit.edu/?p=1229

is it possible to make an ATTiny board to replace the Uno for programming other ATTiny chips?

they appear to have the same pins that are used by the Uno; 'SCK, MISO, MOSI'...

 

Please dont laugh this little guy off the planet. He was a very old robot kit Called Mr. Technoman I'll upload a picture of the box later for fun. The old robot was … Read more

First Robot Plan

I'm about to start my first robot project so i thought i would document my progress, I don't imagine anyone else will be interested so i'm mainly doing this so i have a record.Controller PCB

For a project at Uni I have made a Wireless controller and a motor driver PCBs. They both include a built in arduino and communicate via XBees. I get to keep the PCBs from the project and have bought the ATmega328 chips, XBees and a chassis as these are the parts we had to return.

I plan to use this as a base for my robot and add more features as and when i can.

How to get an Arduino Uno + Rover 5 up and running

Hi

I first touched an Arduino last November.  Come Christmas, Santa left a 4-motor Rover 5 under the tree for me and the kids.  As far as I can tell I can't just hook this up to an arduino board, but need to have additional controllers.  What is the best way of doing this?

[I have an Arduino Uno.  Will the Rover 5 work with a Uno?]

What's the easiest way to get it running? Should I be buying a Dagu 4 channel motor controller?  Would that get me there? Someone mentioned the Pololu TB6612FNG Dual Motor Driver Carrier.

Pointers?

RAD 2.0 Schematic?

Does anyone have a schematic or diagram outlining the electrical components for a RAD 2.0?
