Robot Wars returning to BBC2!

Just looked on their page seems they cant join the party :( and the bbc don't seem to be giving competitors long to prepare new bots

I didn't see that. It's a shame :( two months is not really anywhere near enough time to build a bot, I hope the series isn't poor as a result.

That's my worry as well. I have also seen that they are allowing spinners even though they have been banned the past few years, are we going to see any decent ones this year?
 
Staying kinda on-topic, does anyone know what physics are involved in this picture / video? It concerns the robot with the vertical blade. When it revs up, the robot starts flipping up on its side. It's comical to watch :D It doesn't seem to affect the red horizontal-bladed robot though.

It's disc was possibly damaged in the first impact such that it's subsequent shape meant it generated thrust, sufficient enough to tip it up. Either that or some sort of gyroscopic effect.
 
Thanks Jokester :-) Yes, it could well have been from de-shaping caused by the impact... possibly loss of symmetry? Certainly a physics phenomenon and would be forces / kinetic energy related. It does affect a few other robots from Robo Challenge too, but again only the ones with vertical blades, not horizontal ones.
 
The other thing that springs to mind was some sort of torque effect similar to a helicopters rotor blade requiring the tail rotor to counter it.
 
Does it have some sort of pneumatic lifting device? Or is that the blade catching the floor and causing it jump?

Have you ever done that thing when you have a bicycle wheel with a handle on each end of the axle? When you spin it really fast and hold it, it becomes quite difficult to move it about and it starts to really pull you around.
 
So Dara O'Brien and Angela Scanlon are going to be hosts. Shame it's not Craig Charles but I quite like Dara. Not familiar with Angela though.

The gyroscopic effect?
