We mounted all three of the motors on the robot in a way which keeps the master unit down, keeping to our original goal of keeping the center of gravity down.
This is what we started the lesson with, prototype robot base and the attacking weapon.
To be done this lesson:
* Mount third motor.
* Install rear suspension (And not just any suspension.... but independent rear suspension ;)).
* Install lifting weapon ready to get connected to motor.
We started with this assortment of robot parts:
And turned them into the awesome beast below!
Since Lockie and I decided to keep the center of gravity low the top motor will need to be moved lower, high center of gravity means it can get tipped and/or lifted easier which we don't want.
Now on to the suspension!
This current suspension is just a quick prototype independent suspension (probably overkill for a battle robot), but will ensure that we always have lots of wheels on the ground which you know it = grip. Although if the robot does get lifted the center of gravity will get higher so even though we have 4 wheels on the ground it'll still be vulnerable but its still superior to a solid axle that would render the two wheels on it useless.
As you can see here the suspension can over-extend.... and doesn't remain level during its extension, leaving on part of the wheel on the ground which is not ideal! I have a plan to combat this and keep the extended wheel(s) level during all parts of the extension which will maximize grip. So I'll update the blog with the new and improved suspension unit tomorrow.
Hopefully the structure of the robot will be finished tomorrow or thursday so coding has time to completed and optimized so that we will win.

Great work boys. I was starting to get worried so it is fantastic to see some work being done. I hope you can work out your timetables and get your robot finished for the comp. Good luck.
