Robot overcomes uncertainty to retrieve buried objects

For humans, finding a lost wallet buried under a pile of items is pretty straightforward—we simply remove things from the pile until we find the wallet. But for a robot, this task involves complex reasoning about the pile ...

Artificial skin gives robots sense of touch and beyond

We tend to take our sense of touch for granted in everyday settings, but it is vital for our ability to interact with our surroundings. Imagine reaching into the fridge to grab an egg for breakfast. As your fingers touch ...

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.
