Reliable high speed wireless connectivity between two or more Arduino boards is something that everyone wanting to get rid of a tabletop tangle of wires will eventually need to implement. As part of my ongoing ERP project, I have decided to modify the ERP chassis to carry a GPS and an array of ultrasonic rangefinders. By establishing a wireless datalink, I hope to be able to build an outdoor mapping robot that would be able to map its surroundings and transmit a 3D image back to a base station.
As robots become smarter, faster and more capable, they are being developed to perform increasingly complex tasks. In order to perform these tasks properly, robots are becoming more and more dependent on accurate navigation through the environment in which they operate. Somewhere in the future, if intelligent robots were to rise up and demand fundamental rights, I think one of the first things they would ask for is the answer to the question, “Where am I?”.
