Adding Accessories to my LMR First Robot

I was wondering if i could use the same project board and PICAXE chip to add new part to my first robot - (the "Start Here" bot in LMR).

can i simple buy parts like more servos, propellers, sensors and motors etc. and just keep adding them to the project board?

if so are the 3 non-rechargable batteries enough?

or do i need more power to add more and bigger motors/servos/propellers/sensors?

are parts as easy to program on the same PICAXE chip? or will i need a more powerful chip ??

Thanx a lot for any help and advice...
