The Picnickers - Build Diary(s)

[Fathersplat]

Hey there! I don't think that I've properly introduced myself! I'm Dan, and I've followed robotic combat for practically my whole life (1998-present), but sadly I've never been able to join in on the fun.
BUT
Recently events have aligned themselves in such a way that I have time, tools and expertise on hand to help build my own! Sadly, no money, but I have all the bits and bobs that are needed (I think) already, so I've started to live my dream of building and being able to drive my own robot! So many exclamation marks!
Some of you may have guessed already that I already have robots (22 Lego ones. So mature. :P) and so I'm going to apply mostly the same principles in the non-lego build as I do in the Legos, such as compactness but room to flex, and a way to easily get electronics in and out.

Here's the 'bot so far (ignore the sideways drill motors, the mounting holes haven't been cut yet):

The parts I have:
2x Drill motors (locked with grub screws)
2x Drill batteries (which will be used for cheapness)
1x Sabertooth 2x25a speed control
2x Robochallenge 100mm wheels
1x Spektrum DX3
£15.00 (membership for three)
Do I need to add anything else on to that list?

Sorry for the word wall, i couldn't really help it. Still, if any of you got down here without casualty, thanks for the time!
EDIT: On second thought this isn't actually too long... Still wordy though.
