Aldebaran Robotics Inc. (France)  needed a material for the outer shell of its programmable, 75cm-tall NAO® humanoid robot. The company required an environmental friendly flame-retardant material that also exhibited high impact resistance, dimensional stability and moldability.

Makrolon® polycarbonates and Bayblend® (PC+ABS; PC+ASA blend) resin from Covestro proved to be the optimal materials. The amorphous thermoplastic materials are noted for their outstanding impact strength, superior dimensional stability, excellent thermal resistance, and low-temperature toughness.

NAO®’s outer shell can withstand an extreme temperature range from -40 °C to +120 °C, while also exhibiting good weathering resistance, good thermal stability and easy processing. The materials, which offer improved moldability and scalability for enhanced design freedom, are available in a wide selection of colors for personalized aesthetics.

As a leading global, high-performance materials manufacturer, Covestro’s materials are also found on the exteriors of Myon® (from Humboldt University of Berlin), another humanoid robot and HAL® (from Cyberdyne, Inc.), a battery-operated robot.

The main properties of Makrolon® polycarbonate and Bayblend® (PC+ABS; PC+ASA blend) resin grades are:

  • Easy processing
  • Thermal stability
  • Flame retardant
  • Weathering resistance
  • High impact resistance
