ROBOT SENSORS

ROBOT SENSORS A sensor (also called detector ) is a converter that measures a physical quantity and converts it into a signal which can be read by an observer Features of Sensors • Accuracy – the true value of the variable can be sensed with no systematic positive or negative errors in the measurement. • Precision – it means that these is little or no random variability in the measured variable. • Operating Range – the sensor should posses a wide operating range and should be accurate and precise over the entire range. • Speed of Response – the transducer should be capable of responding to changes in the sensed variable in minimum time. • Calibration – the sensor should be easy to calibrate. • Reliability – the sensors should possess a high reliability. It should not be subject to frequent failures during operation. • Cost and ease of operation – the cost to purchase, install and operate the sensor should be as low as possible. Use of Sensors in Robotics ...

End Effector

End Effector Definition End effector is a generic term that includes all the devices that can be intalled at a robot wrist. Synonyms of end effector are end of arm tooling (or EOAT), robot peripherals or robot accessories although these last two terms are not as precise and can include devices that are not necessarily installed and the end of the robot arm. End Effector Types Classic examples for industrial robots are listed below. Grippers Grippers  are the most common type of end effector. They can use different gripping methods and actuation styles. You can read about this topic in our article on how to  choose the right gripper for your application . Brands of  robot grippers  include Schunk, Robohand, PHD, SOMMER and, of course, Robotiq. Force-Torque Sensors Force-torque sensors  (FT sensors) are pucks installed between the robot flange and the tool that interacts with the part. They measure the force and torque that the robot applies to t...
