I've been meaning to build a vehicle using arduino components and LEGO. I have a mechanical clamp built with arduino which will be locked on top of a custom LEGO build (It should be made out of LEGO blocks and arduino sensors). In my mind, it resembles a crawler.
I've been looking for a way of controlling it remotely. I only have experience with IR controllers but I'm not sure if this technology would fit for my project.
What I'm looking for is a technology wich could transmit data to an Arduino board (thus, an emitter and a receiver component) which, in my case, could comfortably handle a veichle.
Plus, it should have a range of action of at least 5 meters (15 ft).
If such technology exists, do you know any controller which could do the job for me?
