Fast algorithms to test robust static equilibrium for legged robots

Andrea Del Prete, Steve Tonneau, Nicolas Mansard
2016 2016 IEEE International Conference on Robotics and Automation (ICRA)  
We extend all the discussed techniques to test for robust static equilibrium, that is the ability to maintain equilibrium while avoiding to lose contacts despite bounded force-tracking errors.  ...  Accounting for robustness does not affect the computation time of the equilibrium tests, while it qualitatively improves the contact postures generated by our reachability-based multicontact planner.  ...  Test 3 -Planning with Robust Static Equilibrium This last test compares the postures generated by our contact planner using the standard equilibrium test and the robust one.  ...

inside debt induces CEOs to pay dividends while convex CEO compensation decreases dividend payout.  ...  Using inside debt (i.e., pensions and deferred compensation) and the sensitivity of CEO equity compensation to stock price changes (i.e., high CEO delta), as proxies of CEO risk aversion, we document that  ...  In our sixth and final robustness test, we examine whether our findings are robust to market conditions in a more direct way.  ...
