Humanoid and mobile robots are pushing precision gearing into a new design space. Engineers must now balance accurate positioning, rigidity, torque density, efficiency and weight within increasingly compact joints.
In this interview from Automate 2026 in Chicago, Nidec Drive Technology walks through the technologies it is developing for advanced robotics and industrial automation, including FLEXWAVE strain-wave reducers, KINEX cycloidal gearboxes and high-precision planetary systems.
Rather than simply listing specifications, the discussion focuses on the engineering questions behind the hardware. Why does zero backlash matter so much in robotic motion? How can a compact gearbox absorb high shock loads? When does it make sense to integrate the gearing directly into a robot joint instead of using a complete standalone unit?
Peter Sparopoulos and Scott Asher also discuss the trend toward lighter, more integrated robotic actuators that combine gearing, motors and sensors. They explain what robot manufacturers are asking for as systems move from fixed industrial equipment toward battery-powered mobile and humanoid platforms.
View All The conversation also touches on servo motor compatibility, modular adapter designs, customization and the challenge of moving quickly from prototype development to mass production without sacrificing quality.
