What is operational space?
The operational space (also called task space) provides an alternative, more natural space, for such a definition. More specifically, it is the inverse mapping which is often of interest: given a task, what are the actions required in the joint space to achieve it.
What is operational space control?
Operational space control (OSC) is one of the most elegant approaches to task control for complex, redundant robots. Applications of OSC range from end-effector control of manipulators up to balancing and gait execution for humanoid robots [1].
What is joint space scheme?
Joint-space trajectory generation is in common usage in robotics to provide smooth, continuous motion from one set of joint angles to another, for instance, for moving between two distinct Cartesian poses for which the inverse pose solution has yielded two distinct sets of joint angles.
What is work envelope of a robot?
A robot’s work envelope is its range of movement. It is the shape created when a manipulator reaches forward, backward, up and down. These distances are determined by the length of a robot’s arm and the design of its axes. A robot can only perform within the confines of this work envelope.
What are the parameters must satisfy a machine to qualify as a robot?
Energy A robot needs to be able to power itself. A robot might be solar powered, electrically powered, battery powered. The way your robot gets its energy will depend on what your robot needs to do. Intelligence A robot needs some kind of “smarts.” This is where programming enters the pictures.
What are the factors that affect the size and shape of work envelope?
The size and shape of the work envelope depends on the coordinate geometry of the robot arm, and also on the number of degrees of freedom. Some work envelopes are flat, confined almost entirely to one horizontal plane. Others are cylindrical; still others are spherical. Some work envelopes have complicated shapes.
How are operational space and joint space independent?
Similarly, the robot can choose any joint space configuration it desires, independent of any operational space parameters. So it would seem these two spaces are completely independent. It is the act of having the robot perform tasks that relates and constrains the two spaces.
Who are the members of the joint space operations center?
The core cadre of personnel from the Joint Space Operations Center was provided by the Air Force’s (now Space Force’s) 614th Air Operations Center, but other space personnel from the Army, Navy, and Marine Corps also were tasked to the JSpOC.
How are kinematics related to operational space and joint space?
It is the act of having the robot perform tasks that relates and constrains the two spaces. Once you task a robot to “move to point A (in operational space),” you have just built an implicit constraint on the robot’s joint space such that it must use the x → = K ( q →) kinematics to move to point A.
What does combined Space Operations Center stand for?
The Combined Space Operations Center ( CSpOC) (formerly the Joint Space Operations Center (JSpOC)) is a command and control (C2) weapon system focused on planning and executing US Strategic Command ‘s Joint Functional Component Command for Space (JFCC SPACE) mission.
