NAO Review (3★)

Editorial

NAO remains the most accessible entry point for humanoid research and STEM education, but its 2018-vintage hardware now feels dated against newer platforms. The 25-DoF platform and mature NAOqi ecosystem deliver reliable classroom results at ~$8,000–$17,000, yet the 60–90 minute battery and 0.4 m/s gait confine it to tabletop or short demos. Overheating and support uncertainty following Aldebaran’s 2025 bankruptcy further erode long-term lab viability. While 13,000+ deployments prove its pedagogical value, institutions should budget for frequent recharges and eventual migration to more robust successors. For pure education and basic HRI experiments it still earns its keep; for anything beyond that it is a legacy tool.

What this assessment is based on

Published manufacturer specifications, deployment reports, and operator accounts. ZeroGantry does not claim hands-on testing of this unit unless stated. Scores are editorial judgments from those public sources — see the methodology for how labels are assigned.

Pros

• 25 DoF driven by precision Maxon coreless DC motors enabling expressive bipedal gait and gestures
• Over 13,000 units deployed in 70+ countries as the de facto standard for university robotics labs and HRI research
• Rich sensor suite with dual 5 MP cameras, 4 omnidirectional microphones, IMU, sonar, and 8 FSRs per foot
• NAOqi framework with Python/C++ SDK supporting rapid development on Intel Atom E3845 with 4 GB RAM

Cons

• Battery runtime limited to 60 min active / 90 min normal use on 62.5 Wh Li-ion pack
• Maximum walking speed of only 0.4 m/s (0.6 km/h)
• Payload capacity restricted to ~0.5 kg with 3-finger grippers
• Fragile ABS plastic shell prone to motor overheating after 20-30 min; manufacturer entered receivership in 2025 with assets acquired by Maxvision
