The first industrial robot, [1] Unimate, was invented in the 1950s. Its control axes correspond to a spherical coordinate system, with RRP joint topology composed of two revolute R joints in series with a prismatic P joint. Most industrial robots today are articulated robots composed of a serial chain of revolute R joints RRRRRR.
A prismatic joint is a one-degree-of-freedom kinematic pair [1] which constrains the motion of two bodies to sliding along a common axis, without rotation; for this reason it is often called a slider (as in the slider-crank linkage) or a sliding pair. They are often utilized in hydraulic and pneumatic cylinders. [2]
It is a robot whose arm has at least three rotary joints. Parallel robot: One use is a mobile platform handling cockpit flight simulators. It is a robot whose arms have concurrent prismatic or rotary joints. Anthropomorphic robot: It is shaped in a way that resembles a human hand, i.e. with independent fingers and thumbs.
Cartesian robots, [5] also called rectilinear, gantry robots, and x-y-z robots [6] have three prismatic joints for the movement of the tool and three rotary joints for its orientation in space. To be able to move and orient the effector organ in all directions, such a robot needs 6 axes (or degrees of freedom).
Moonlight Basin is a private club in southwestern Montana, located in the Madison Range of the Rocky Mountains in the resort village of Big Sky.It became part of Big Sky Resort in October 2013 when it, along with ski terrain within the Club at Spanish Peaks, were bought and merged into Big Sky Resort, making it one of the largest single ski resorts in the United States, with 5,750 acres (2,330 ...
Disney unveiled its next generation of robots at SXSW Friday. With the head of a bunny and a child-size frame, the robot tumbled out of a box, summersaulted and roller skated during a presentation ...
Also known as parallel robots, or generalized Stewart platforms (in the Stewart platform, the actuators are paired together on both the basis and the platform), these systems are articulated robots that use similar mechanisms for the movement of either the robot on its base, or one or more manipulator arms.
In the study of mechanisms, a four-bar linkage, also called a four-bar, is the simplest closed-chain movable linkage. It consists of four bodies, called bars or links, connected in a loop by four joints. Generally, the joints are configured so the links move in parallel planes, and the assembly is called a planar four-bar linkage. Spherical and ...
