If you rotate the bot quickly on the spot it will reduce the energy in it as well from gyro forces and I haven't ever seen anyone standing with a stop watch at the side of the arena

We've had robot's with this in the past, particularly in featherweights a very free gearbox/bearings is essential so we won't be banning anything that can't spin down fast enough.
However, there are a few provision's that we take with robot's that do take longer to spin down and these will be discussed during tech check (Mouldy will be made aware of these, but it's nothing major).
Two points/question today...
1:Can we know the provisions in advance for the spin down?
2: With Aluminium grading I know approximately the relative costs and better over all properties of each grade but when it comes down to it which would people choose?
1060 is far to weak to be used as armour in internal supports; it just bends.
I have heard of 2014 and 5052 being used in robots.
6061 and 6082 seem very similar but are both better than the first 3 as far as I know.
7075 is the 'best' as far as I know but is it worth cost increase from say 6082?
For bulkheads and axe arms etc then 2014/7075 are about the best. For welding go with the 6082. 5000 series is abit soft and cheap.
With regards to the provision's, its nothing to do with how you build your robot, just a few pointer's for during the event.
Make sure you know what temper of aluminium you're purchasing as that largely effects the strength of the material.
If your're getting 2024 type, temper T0 its rated approx 200Mpa in tensile strength, while in T3 temper its rated approx 300Mpa. Same with 7075, T0 is 300Mpa while T6 is 600Mpa.
7075, and 2024 are aircraft grade aluminium so I think they might be slightly expensive or hard to find.
I've used 6082T6 which is half way between 2024T3 and 7075T6 and its widely available.
Something worth noting is that these alloys are not easy to bend and form and have a tendency to crack in tight angles.
I am guessing that everyone is quite curious to see exactly what Binky is and what it can do. There as still some issues to resolve; mainly around signal and range, but this should sum it up quite nicely.
The secrets are revealed... kind of..

Hahaha, oh maaan. What have you done?! That's crazy! :lol:
I feel for those facing it come April. Something to be feared right there.
Edit: Conker 2 test video gogogogo!
ok :uhoh: this is defiantly the first spinner im scared of :lol:
:shock: That's CRAZY! :shock:
Thats the best new robot video I've seen in years! Look forward to fighting it!
