Welcome to New Scale News, your monthly update on micro-mechatronic systems and applications. This month we're pleased to feature two of our customers and their applications for miniature motion systems.
M3-FS Focus Module excels in industrial robotics application
Miniature focus system with embedded controller is successfull in dynamic stability, vibration and lifetime testing
An industrial equipment manufacturer has found the
M3-FS Focus Module ideally suited for autofocus in a robotic end-of-arm vision system. Their testing shows the M3-FS to operate reliably under acceleration up to 20m/s² in the X, Y and Z axis, with its high dynamic stability minimizing pixel shift as the camera moves.
The vision system uses an M3-FS-1.8-1.5-M12 smart module with a commercial M12x0.5 8 mm diameter lens weighing 3.0 grams.
The module with lens and embedded controller measures only
20 x 23 x 16 mm. The embedded controller simplifies mounting of the vision system at the end of the robot arm.
Vibration testing of the smart module was also successful.
Lifetime testing is ongoing and has exceeded 3 billion steps and 3 million complete up/down movements for a total travel of more than 1 mile... and counting.

Handshake stabilization in microsurgery
The Surgical Mechatronics Lab at the Carnegie Mellon University Robotics Institute demonstrates their "Micron" intelligent handheld instrument.
Using New Scale SQUIGGLE motors in a micro hexapod design, Micron improves microsurgery through active tremor cancellation for better control of a tool tip.
Applications shown in the CMU video are in vitreo retinal surgery, handheld scanning for intraocular optical coherence tomography (OCT), and automated intraocular laser photocoagulation.
