Firstly, enable mirror mode (This can be done by pressing M). We are going to keep this enabled for the whole tutorial.
Now, lets get to work! Start by building this chassis (note that all wheels are steering mk1 and that the 4 corner blocks are tetras):

Now we are going to add 4 light chassis tetras and 4 light chassis prisms.

Now we're going to build the second layer (and add the pilot seat!), here I have 2 screenshots for you. I used 2 inners, 19 prisms and 24 cubes.


Now lets add the windscreen, to place the rear prism I did have to remove the pilot seat and place it on a block but it will be supported by the corner tetras.

Finally, it's time to add the guns!!! (Note: I also added 2 prisms to the rear gun mounts.)

Thanks for reading this guide, I hope this robot will server you well (if you did end up building it).
Please post any suggestions in the comments. Here is the final bot (I added a holo-flag fore some finesse):
