#include <EmergencyStopMC.h>
Inheritance diagram for EmergencyStopMC:
Uses MotionCommand::kEmergencyPriority. Monitors the feedback on joints and adjusts joints to react to pressures above a certain threshold. This allows you to mold the body while it's in this mode, while retaining enough stiffness to hold against gravity.
This MotionCommand is intended to always be left running. It polls WorldState::state for a double-tap on the back button, which causes it to set its joint values. to whatever their current state is. LEDs are left blank, except the tail, which is used to indicate that the emergency stop is on.
A second double-tap will cause it to set all joints to 0 weight
The tail LEDs only ever go up to .5, so that if you really care whether the tail light was set by an underlying behavior/motion, you should be able to tell by looking closely (if blue is going from .5 to 1, that's because it's already set)
