NASA InSight's 'Mole' is out of sight

NASA's InSight lander continues working to get its "mole"—a 16-inch-long (40-centimeter-long) pile driver and heat probe—deep below the surface of Mars. A camera on InSight's arm recently took images of the now partially ...

A camera closes in on a detailed model satellite, to simulate the extreme "guidance navigation and control" (GNC) challenge of rendezvousing with an uncooperative target, such as a derelict satellite or distant asteroid.

US probe to touch down on asteroid Bennu on October 20

After a four-year journey, NASA's robotic spacecraft OSIRIS-REx will descend to asteroid Bennu's boulder-strewn surface on October 20, touching down for a few seconds to collect rock and dust samples, the agency said Thursday.

NASA's new Mars rover will use X-rays to hunt fossils

NASA's Mars 2020 Perseverance rover has a challenging road ahead: After having to make it through the harrowing entry, descent, and landing phase of the mission on Feb. 18, 2021, it will begin searching for traces of microscopic ...

NASA's InSight flexes its arm while its 'mole' hits pause

NASA's InSight lander has been using its robotic arm to help the heat probe known as the "mole" burrow into Mars. The mission is providing the first look at the Red Planet's deep interior to reveal details about the formation ...

Robotic arm

A robotic arm is a robot manipulator, usually programmable, with similar functions to a human arm. The links of such a manipulator are connected by joints allowing either rotational motion (such as in an articulated robot) or translational (linear) displacement. The links of the manipulator can be considered to form a kinematic chain. The business end of the kinematic chain of the manipulator is called the end effector and it is analogous to the human hand. The end effector can be designed to perform any desired task such as welding, gripping, spinning etc., depending on the application. For example robot arms in automotive assembly lines perform a variety of tasks such as welding and parts rotation and placement during assembly.

In space the Space Shuttle Remote Manipulator System also known as Canadarm or SSRMS and its successor Canadarm2 are examples of multi degree of freedom robotic arms that have been used to perform a variety of tasks such as inspections of the Space Shuttle using a specially deployed boom with cameras and sensors attached at the end effector and satellite deployment and retrieval manoeuvres from the cargo bay of the Space Shuttle.

The robot arms can be autonomous or controlled manually and can be used to perform a variety of tasks with great accuracy.

The robotic arm can be fixed or mobile (i.e. wheeled) and can be designed for industrial or home applications.
