10.9 million names now aboard NASA's Perseverance Mars rover

NASA's "Send Your Name to Mars" campaign invited people around the world to submit their names to ride aboard the agency's next rover to the Red Planet. Some 10,932,295 people did just that. The names were stenciled by electron ...

Curiosity Mars rover takes a new selfie before record climb

NASA's Curiosity Mars rover recently set a record for the steepest terrain it's ever climbed, cresting the "Greenheugh Pediment," a broad sheet of rock that sits atop a hill. And before doing that, the rover took a selfie, ...

Refueling satellites in space with the help of a robot

Many technologies that are essential for daily life—from communications to GPS navigation to weather forecasting—rely on the thousands of satellites that are orbiting Earth. When those satellites run out of gas and stop ...

Mars InSight's 'mole' is moving again

NASA's InSight spacecraft has used its robotic arm to help its heat probe, known as "the mole," dig nearly 2 centimeters (3/4 of an inch) over the past week. While modest, the movement is significant: Designed to dig as much ...

NASA's push to save the Mars InSight lander's heat probe

NASA's InSight lander, which is on a mission to explore the deep interior of Mars, positioned its robotic arm this past weekend to assist the spacecraft's self-hammering heat probe. Known as "the mole," the probe has been ...

Robotic toolkit added to NASA's Mars 2020 rover

The bit carousel—a mechanism that will play a key role in the acquisition, containment and eventual return to Earth of humanity's first samples from another planet—has been incorporated into NASA's Mars 2020 rover.

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.
