Now basic physics would say that yeah, its 1/sqrt2 because the force is being applied at a 45deg angle, but the odd thing is, when you get out the other xy component vector, it doesnt seem to be applying a force when the robot drives straight assuming the omniwheels have no significant friction to lateral movement. Now im sure no one got that, but if you did, help me cause im really stumped by this...
the setup you showed is similar to team 180's and 1083's 2004 robots.
i'm pretty confident that that you're right with the second one ,[sqrt2]% of available motor power (but then again, i've been awake way too long). that is the reason i think the mecanum/ilon wheel setup is better, since it allows the motors to apply 100% of their power to full forward/back or left/right movement.
