Detailed Description

An entity that stores the state of a robot gripper.

This class provides a component that stores the state of a robot gripper. The state is represented by a Real value between 0 and 1, where 0 means unlocked and 1 means locked. In-between values are also allowed. The transition between locked and unlocked state is when the lock state exceeds m_fLockThreshold, which is set to 0.5 by default.

The gripper can also be oriented, acting on its offset and direction attributes. The offset refers to the position of the gripper with respect to the reference point of the robot. The direction refers to where the gripper is facing.

Constructor & Destructor Documentation

argos::CGripperEquippedEntity::CGripperEquippedEntity ( CComposableEntity pc_parent)

Class constructor.

This constructor is meant to be used with the Init() method.

Parameters
pc_parentThe parent of this entity.

Definition at line 20 of file gripper_equipped_entity.cpp.

argos::CGripperEquippedEntity::CGripperEquippedEntity ( CComposableEntity pc_parent,
const std::string &  str_id,
const CVector3 c_offset,
const CVector3 c_direction,
Real  f_lock_threshold = 0.5f 
)

Class constructor.

This constructor is meant to be standalone. You should not call Init() after using this constructor, or memory leaks are likely to happen.

Parameters
pc_parentThe parent of this entity.
str_idThe id of this entity.
c_offsetThe positional offset of this gripper with respect to the robot reference point.
c_directionThe facing direction of this gripper.
f_lock_thresholdThe lock value above which the gripper is considered locked.
