Current obstacles

  • Competition from low-cost cobotsChinese cobot makers compete hard on price.

Physics limits

  • Contact limits cap speedA cobot must not hit a person harder than set pain and injury limits for each body part. Force grows with moving mass and speed, so cobots stay slower and lighter than caged robots.
  • Sensitive versus nuisance stopsDetecting a gentle bump means reading small force changes against the arm's own weight and motion. Set it too sensitive and it stops for nothing; too dull and it hits too hard.
  • Light arms bendCobot arms are light for safety, so links and joints flex under load. Precision drops as payload and reach grow.

Sensing

Contact detection in the joints

Sensors in the arm detect unexpected force and stop it, so CRX arms can work beside people without a safety cage.

Teaching

Guide by hand, program on a tablet

Operators pull the arm to teach positions and arrange steps as icons on a tablet, with no robot code.

Range

One family, many sizes

CRX models run from the light CRX-3iA to arms carrying 25 kg or more, all on a compact Fanuc controller.
