In the linked video, I’m pretty sure that they had a rubber band going from the anti-tip to in between two meshed gears of the drive. I’ll send a picture to clarify.
As you can see, the rubber bad is placed between the gears, so when the gears rotate after the robot moves forward, the rubber band is released. letting the anti tip free. Hope this helps!
Yeah, I just wanted to explain to him how the mechanism in the video works. I should have explained not to directly place it in the gears, that’s my bad
Flip out anti-tips are good for an easy build in terms of spacing, however, are bad as they have the potential to be easily folded back into starting position by another robot
Slider anti-tips are less likely to be pushed in (as they constantly have pressure) but are bad due to the possibility of friction and bad for spacing for many teams.
