Industrial Robots: Encoders for Tool Center Point Accuracy

The use of secondary encoders on all of a robot's axes, as well as the use of linear encoders for positioning the robot relative to the workpiece, enables a level of accuracy at the tool center point

Encoder Selection: Speed Control

A general in depth analysis shows that the highest encoder resolutions are required for very precise speed control. The encoder resolution increases with the square of the demanded speed accuracy.

Tru-Trac™ Keeps Frankenstein Alive

This machine was assembled from various parts from other machines, so "Frankenstein" was really the only logical name for it.

What IS an Encoder?

Encoders use different types of technologies to create a signal, including: mechanical, magnetic, resistive and optical - optical being the most common.

maxon motor's - Exoskeleton Joint Actuator

A brushless DC motor solution for use in hip and knee exoskeletons. This complete joint actuation unit consists of motor, gearhead, encoder and position controller. Fitting absolute encoder directly at the joint rotation provides designers increased positioning accuracy. The unit will deliver 54Nm of continuous torque and 120Nm on a 20% duty cycle. The system can be operated on supplies between 10 and 50V DC and the actuation speed is up to 22rpm.
