A science fair or engineering fair is an event hosted by a school that offers students the opportunity to experience the practices of science and engineering for themselves. In the United States, the Next Generation Science Standards makes experiencing the practices of science and engineering one of the three pillars of science education.
A gripper is something that grips things or makes it easier to grip things. It may refer to: grippers, tools for building hand strength; a Robot end effector, the "hand" of a robot; a person working in a grip (job), a position held in filmmaking
A mass market, plastic-handled gripper A gripper being closed. Grippers, sometimes called hand grippers, are primarily used for testing and increasing the strength of the hands; this specific form of grip strength has been called crushing grip, [1] which has been defined as meaning the prime movers are the four fingers, rather than the thumb.
The Google Science Fair was a worldwide (excluding Cuba, Iran, North Korea, Sudan, Myanmar/Burma, Syria, Zimbabwe and any other U.S. sanctioned country [1]) online science competition sponsored by Google, Lego, Virgin Galactic, National Geographic and Scientific American. [2] [3] [4] It was an annual event spanning the years 2011 through 2018.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
Started in 1962, the Canadian-Wide Science Fair (CWSF) is an annual science fair in Canada coordinated by Youth Science Canada. Finalists qualify from approximately 25,000 competitors at over 100 Youth Science Canada-affiliated regional science fairs in every province and territory, or, in the province of Quebec , the provincial science fair.
In the strict definition, which originates from serial robotic manipulators, the end effector means the last link (or end) of the robot. At this endpoint, the tools are attached. In a wider sense, an end effector can be seen as the part of a robot that interacts with the work environment.
This is the cause of a net force on the object in the direction normal to the side with higher local pressure. A Bernoulli gripper takes advantage of this by maintaining this negative pressure at the gripper face compared to the ambient pressure below the sample, while maintaining an air gap between the gripper and the object being held.
