Hi Ben
Welcome to the weird and wonderfull world of robots,

For your first robot as said by others best to go for a simple push bot to start this can be done very cheaply around £100. then later on you can evolve the running chassis you have to encorporate a wepon such as a lifter or a co2 powered flipper .

Basics first is get yourself a transmitter and receiver set up ( 2.4ghz ) recommended
around £45 then a couple of cordless drills this give you motors and batteries around £10 each two servos and 4 microswitchs makes for a direction controler ( note i didnt say speed controler) as this give full drive in either direction as most newbies use full throttle anyway why bother with a speed controler they come later ,

Then you need to design your robot shape and make your chassis bear in mind what you need to fit in place it all in your chassis cover paint and have loads of fun .

This forum is a wealth of knowledge so use it dont be afraid to ask questions as we all like to help out and bring along new roboteers ....
