Two-armed 3-D printing

Twin robotic arms work together as part of a project to construct what will be the largest, most complex object ever 3-D printed in titanium: a test version of the 3-m diameter 'optic bench' at the heart of ESA's Athena X-ray ...

Robot 3-D prints replacement bracket on headlamp

In a world first, Swinburne's Repairbot project has achieved a major milestone, using a robot to successfully 3-D print a replacement lug on an automotive headlamp assembly.

Robot lifts bits of melted fuel at Japan's Fukushima plant

A robot arm has successfully picked up pebble-sized pieces of radioactive fuel at Japan's Fukushima nuclear plant in a complex operation seen as key to clean-up efforts after the 2011 meltdown, officials said Thursday.

Curiosity says farewell to Mars' Vera Rubin Ridge

NASA's Curiosity rover has taken its last selfie on Vera Rubin Ridge and descended toward a clay region of Mount Sharp. The twisting ridge on Mars has been the rover's home for more than a year, providing scientists with ...

InSight places first instrument on Mars

NASA's InSight lander has deployed its first instrument onto the surface of Mars, completing a major mission milestone. New images from the lander show the seismometer on the ground, its copper-colored covering faintly illuminated ...

InSight Mars lander takes its first selfie

NASA's InSight lander isn't camera-shy. The spacecraft used a camera on its robotic arm to take its first selfie—a mosaic made up of 11 images. This is the same imaging process used by NASA's Curiosity rover mission, in ...

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.
