Precision Feedback for Collaborative Robots

Encoders measure rotation and return a digital signal that reports the angle of rotation (absolute encoders) or rate of motion (incremental encoders) to the control system. The ‘right' encoders for cobots need to be accurate, reliable, and compact, with excellent dynamic response characteristics. They also need to be reasonably priced. POSITAL-FRABA has responded to this challenge by developing new sensing technologies - such as magnetic and capacitive rotary encoders - that provide cobot manufacturers vital feedback for closed-loop control systems.

POSITAL Kit Encoder for Servomotors and Robots.

A very exciting development in the area of robotics is the development and growing popularity of so-called collaborative robots, or "cobots". Cobots, in contrast to traditional industrial robots, are designed to interact with human workers in a shared workspace. They are typically smaller and less powerful than traditional factory robots and are equipped with a variety of proximity sensors, load sensors and other features designed to avoid dangerous collisions between the robots and the people working around them. This focus on safety means that cobots are easier to deploy in a normal factory setting, since they dont required special fenced off operating areas. Cobots have been used to perform repetitive tasks in light assembly, packaging, materials handling and medical laboratories. Cobots have also been used to help workers avoid direct contact with environments not conducive to direct human interaction, such as high temperature environments, chemically aggressive reagents and toxic pathogens.

Enabling Technologies for the Cobot Revolution
Many cobots are designed to mimic a human arm, with flexible "shoulder", "elbow" and "wrist" joints. Accurate measurement of the rotary position of these joints is central to enabling the cobots control system to keep track of the spatial orientation of all of its moving parts. This is typically provided through rotary encoders mounted in each of the devices joints.

Model TR1 Tru-Trac

Model TR1 Tru-Trac

The Model TR1 Tru-Trac® linear measurement solution is a versatile option for tracking velocity, position, or distance over a wide variety of surfaces. An integrated encoder, measuring wheel, and spring-loaded torsion arm in one, compact unit, the Model TR1 is easy to install. The spring-loaded torsion arm offers adjustable torsion load, allowing the Model TR1 to be mounted in almost any orientation - even upside-down. The threaded shaft on the pivot axis is field reversible, providing mounting access from either side. With operating speeds up to 3000 feet per minute, a wide variety of configuration options - including multiple wheel material options - and a housing made from a durable, conductive composite material that minimizes static buildup, the Model TR1 Tru-Trac® is the ideal solution for countless applications.
