First robot build - Trident (FW) Need help plz

[Doodle2411]

Hi
So, I'm new to this robot building thing, but have been a big fan of the sport for almost 12 years. So me and some friends have decided to build a robot.

We wanted it to be a featherweight to lower cost as we have little money, I am patient to wait to build it, but don't want it to become a forgotten project.

We all wanted a flipping robot with 2 wheels, I added to this by saying make the flipper have 3 spikes, the idea is that the robot has 3 spikes, 2 that go up and one that goes down, this design is similar to the way Malestrom's flippers work if you have ever seen it in action.

The dimensions are
Height: 15cm
Length: 35cm without weapon: 50cm with weapon
Width:25cm

Our shopping list so far goes as follows
2x Bosch 18v Cordless NiCd drill
2x Colson Performa flat tred grey 6 inches
And 3mm aluminium

I don't know what speed controllers, transmitter, reciver to use so plz comment if you can help me build this robot and tell me what I'm doing wrong and what I'm missing

Your support is appreciated
Many thanks
