Team Titanium's Teeter-Totter Talons

So, It would appear that robots don't move after the "talons" have pushed the bridge to level, but somehow, the bridge balances.
Is this because the CoM is in a position that it could be balanced, if the bridge were moved to level? (ie. tri-stable)

Looking good and making KC teams proud!

I think the benefit is two-fold:
The CG of the robots swings into balance or close to balance as the bridge tips. Picture the CG floating somewhere several inches above the center of the bridge surface, but not yet above the center bump because it is at an angle. As the bridge tips the CG rotates to a position above or close to above the center bump = balanced. This effect is greater as the robots are taller with a higher CG.
The second benefit is that of simply being horizontal. It is easy for nearly any robot to tweak and hold their position when horizontal, rather than on an incline.

Solving a statics problem is generally simpler than solving a dynamics problem...in engineering and in driving robots.

Just be glad they aren't Team Titanium's Tater Tot Talons.

We tried tater tots in trials, they tended to tear in two under tipping tension.

Being a team that competed at the St. Louis Regional your robot was GREAT! One thing that I did notice was sometimes during the balancing the talons moving would cause your bridge to become UN-balanced. If there was a way for your robot to retract the talons without moving the complete arm, I do believe it would help you balance more.

But just a thought

They are off the ground during balance and do not actually need to be retracted. I don't recall their retraction ever spoiling the balance. We did push too hard once and tipped the other way, then used them again on the second tip.

Looks like you made at least some improvements since KC. Not that your robot wasn't good enough anyway... Congratulations on such an amazing robot
