Need Robot Parts

There are lot of online stores from where you can get the robot parts but i really like the www.robotshop.ca for this purpose, they support variouse payment methods including money order and wire transfer. you can also use paypal. Following are some caretories fromar robotshop.ca.

iRobot Roomba Parts Microcontrollers Sensors Motor Controllers Motors and Actuators Communication and Control Power Systems Software LCD and Display Interface Adapters and Converters Cables, Wires and Connectors Components

There are also lot of sotres in UK but if you live in Ireland, you can 

get some electronic items from Peats and Maplin, 

but they dont have a wide range of robotic items. so you many need to order online.
