Ultrasonic vibration machining allows extremely complex and non-uniform shapes to be cut into the workpiece with extremely high precision. [ 4 ] Machining time depends on the workpiece's strength, hardness , porosity and fracture toughness ; the slurry's material and particle size; and the amplitude of the sonotrode's vibration. [ 4 ]
A harmonic scalpel cuts via vibration. The scalpel surface itself cuts through tissue by vibrating in the range of 55,500 Hz. The high frequency vibration of tissue molecules generates stress and friction in tissue, which generates heat and causes protein denaturation.
The PUMA (Programmable Universal Machine for Assembly, or Programmable Universal Manipulation Arm) is an industrial robotic arm developed by Victor Scheinman at pioneering robot company Unimation. Initially developed by Unimation for General Motors , the PUMA was based on earlier designs Scheinman invented while at Stanford University based on ...
The Ultrasonic/Sonic Driller/Corer (USDC) is a drilling device that uses vibrations in order to hammer its bit through materials, as opposed to traditional drilling methods. The drill uses a piezoelectric actuator as its source of power, and utilizes a variety of 'horns' to vibrate, or hammer, its bit through the material.
The animated feature adapted from the popular children's books crafts a lovely, bittersweet parable of parenting.
It is an arm-like mechanism that consists of a series of segments, usually sliding or jointed called cross-slides, [2] which grasp and move objects with a number of degrees of freedom. In industrial ergonomics a manipulator is a lift-assist device used to help workers lift, maneuver and place articles in process that are too heavy, too hot, too ...
A surgical robot's end effector could be a scalpel or other tool used in surgery. Other possible end effectors might be machine tools such as a drill or milling cutters. The end effector on the space shuttle's robotic arm uses a pattern of wires which close like the aperture of a camera around a handle or other grasping point. [citation needed]
Robai’s primary product is the line of Cyton [1] robotic arms. [2] These robot arms have seven degrees of freedom and are kinematically redundant with a structural layout similar to that of the human arm. They are able to reach around obstacles and reconfigure while manipulating objects.
