Precision assembly of parts (HDD) through

One robot grasps server HDDs and installs them into the server. Force sensors enable assembly in deep locations which would be difficult using only vision sensors.

Solutions to the Issues


Demands for automation unaffected by variations in parts processing accuracy (dimensions) and assembly accuracy of upstream processes are increasing. For assembly that requires precision assembly while protecting parts, in some cases it’s necessary to press with a certain force for a certain amount of time, and in some cases it’s necessary to record it.


  1. Robot takes out HDD.
  2. HDD is brought close to the rack insertion slot.
  3. HDD is inserted deeply into the rack while using force sensors in the same way that human hands assemble.


  • 【Part/product loss reduction】
  • Force sensors detect and prevent workpiece damage, etc. during apart assembly.
  • 【Traceability control】
  • Force data during assembly are collected in real time.Data can be utilized for quality control.
  • 【Automatic positional shift compensation】
  • Force sensor and vision sensor compensate for variations in workpiece processing accuracy or set position, contributing to stable equipment operation.
  • 【Assembly in deep locations】
  • Force sensor searches to enable assembly even in locations that are difficult to detect with vision sensor.
