I have made some changes to the bot based of the comments.
These include:
Change to the spinner size
Attachments on the spinner
The forks under the bot, acting as a scoop and damage source
The armour level (which is now at Plastic 5)
The weight has changed to 242.6
The wheel size has stayed the same as I wish for the bot to be invert-able, but if this does become a problem that I can't ignore, then the wheel size will be changed.
As you can see, the spinner is the part that has had the most work, however the position of the motor has not been changed.
The 2 Mini Vlad spikes have the swapped out for the forks instead which has given it better stability, but it has raised the height of the spinner and changed the spinner angle, which is still to be tested.
I must give a big thanks to DemonOfTomorrow for the idea of changing the attachments to the spinner, which allowed me to change the spinner size, forks and armour of the bot which has in turn also helped out with the problem Mouldy brought to my attention.
Once again, thanks to the both of you for the advise.
