Abstract

An angular calibration tool is shown in Figs. 1a and 1b, representing top and side views, respectively. It consists of a calibrated (incremented) wheel 1 and vernier pointer 2 that are attached to the shaft and body of a rotary motor 3 to be calibrated. As the shaft of motor 3 is turned, the number of degrees of rotation can be read from the calibrated wheel. The accuracy is within 6 feet of the true angle. With a set of collets, the device is adaptable to fit a variety of shaft sizes and can be used on any number of a rotary devices where angular measurements are needed.

Angular Calibration Tool

An angular calibration tool is shown in Figs. 1a and 1b, representing top and side views, respectively. It consists of a calibrated (incremented) wheel 1 and vernier pointer 2 that are attached to the shaft and body of a rotary motor 3 to be calibrated. As the shaft of motor 3 is turned, the number of degrees of rotation can be read from the calibrated wheel. The accuracy is within 6 feet of the true angle. With a set of collets, the device is adaptable to fit a variety of shaft sizes and can be used on any number of a rotary devices where angular measurements are needed.

The device is useful in a computer controlled robotics environment where the degrees of rotation of rotary actuators needs to be determined, for example, during software "learning" routines.
