Carlsbad, California - At the Automate 2015 show in Chicago, SMAC Moving Coil Actuators introduced a prototype version of the world's first direct drive servo motor robotic finger, acknowledged as a technological breakthrough by a leading European technical university. It is shown here operating a Samsung Galaxy touchscreen phone. SMAC expects an early 2016 release to be shortly followed by a robotic thumb and ultimately the first true functional robotic hand capable of reproducing work done by human hands.


The motor is a servo "partial" motor and is equipped with an SMAC rotary encoder with 15.5K counts per revolution. It achieves a high torque/diameter ratio due to the proprietary magnetic circuit design as well as the coil design. Intellectual property rights have been addressed.

Another - larger motor (35MM) acts as the 2nd joint (MCP FLex). It puts out a torque of 630 mNm and thus can exert a resultant force of 7N at the tip. Both motors move +/- 45 degrees - as the human joints do.

The 3rd motor operates as the first joint (MCP Abd). This is the joint that moves side to side. This motion is based on SMAC's moving coil linear design and already meets the required parameters.

These motors have been integrated into a structure that allows them to operate and cover the same movement capability as a human's finger. The structure weighs approximately 350 grams and is physically about 1.5 x larger than the average male finger.

This major breakthrough in robotics will next be presented live to the public by company president, Ed Neff, at Hannover Messe in Germany and later in the year at the International Robot Exhibition in Tokyo, Japan.

About SMAC, Inc.: Founded in 1990 in Carlsbad, California USA, SMAC has now grown to become a world leader in Moving Coil technology and is now the largest manufacturer of Moving Coil Actuators in the world. SMAC manufacturers on a global basis with production, technical support and service facilities in the USA, Europe and Asia. SMAC manufactures precision programmable electric actuators based on moving coil technology. These actuators are unique in that force, position and speed are totally programmable. They are designed to perform at exceptionally high speeds or very low speeds and with sub-micron accuracy and verifiable repeatability.
