21st century robots are much more than heavy-duty industrial robots. They can be small, mobile, intelligent machines, used anywhere from the home to the battlefield or hospital. These robots must be compact, energy efficient, and versatile. US Digital® optical encoders are a perfect solution for robotics, offering an excellent balance between price and performance in a compact package.

Speed Control

Precise speed is critical for controlling autonomous robot movement in environments where collisions with other machines or humans are possible. US Digital® encoders provide the ideal solution for this type of application, as the small package size allows system designers to optimize their designs without having to give up on performance specifications.

Position Control

When controlling robotic end effector's position, absolute encoders are the preferred solution. US Digital® absolute encoders are unique in the market as they offer high performance without the complicated communication protocols normally associated with absolute encoders. The compact size of the miniature magnetic MA3 encoder means that absolute encoders can be used in creative and tight spaces; the designer no longer needs specialized hardware or software to interact with the encoder, opening up a new world of possibilities.

Energy efficiency is king in robotic applications requiring batteries, and brushless DC motors are becoming more prevalent in designs. The new EC35 commutation encoder incorporates both the commutation functionality provided by Hall Effect sensors and the high resolution encoder functionality into one integrated package. This allows for tighter control between the encoder output and the motor commutation in a reliable and compact manner.
