InSight Mars lander gets a power boost

The team behind NASA's InSight Mars lander has come up with an innovative way to boost the spacecraft's energy at a time when its power levels have been falling. The lander's robotic arm trickled sand near one solar panel, ...

Old SpaceX capsule delivers new crew to space station

A recycled SpaceX capsule carrying four astronauts arrived at the International Space Station on Saturday, the third high-flying taxi ride in less than a year for Elon Musk's company.

NASA's InSight detects two sizable quakes on Mars

NASA's InSight lander has detected two strong, clear quakes originating in a location of Mars called Cerberus Fossae—the same place where two strong quakes were seen earlier in the mission. The new quakes have magnitudes ...

Corridor test of Proba-3's formation flying sensors

The longest corridor in ESA's largest establishment was turned into a test site for one of the Agency's most ambitious future missions, Proba-3. The two satellites making up this mission will line up so that one casts a shadow ...

Dynamic 3-D printing process features a light-driven twist

The speed of light has come to 3-D printing. Northwestern University engineers have developed a new method that uses light to improve 3-D printing speed and precision while also, in combination with a high-precision robot ...

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.
