Questions
SO-101 vs Optimus FAQs
Which is better, SO-101 or Optimus?+
There is no defensible overall robot winner without a target task and environment. Compare form factor, availability, payload, runtime, speed, sensing, control, safety, and price; green highlights apply only to specifications with an explicit direction.
Which can carry more, SO-101 or Optimus?+
A direct answer is unavailable because SO-101 does not publish a normalized payload (kg) in the current source.
Which runs longer, SO-101 or Optimus?+
A direct answer is unavailable because SO-101 does not publish a normalized runtime (hours) in the current source.
Which is faster, SO-101 or Optimus?+
A direct answer is unavailable because SO-101 does not publish a normalized maximum speed (m/s) in the current source.
Which costs less, SO-101 or Optimus?+
A normalized price comparison is unavailable. SO-101: Bill-of-materials cost varies. Optimus: Not commercially available.
Can I buy SO-101 or Optimus today?+
SO-101 is recorded as open build (LeRobot publishes assembly and sourcing instructions rather than selling a single finished configuration.); Optimus is prototype (Tesla presents Optimus as an active robotics development program; no public purchase channel is cited.). Availability can be regional or customer-specific.
What are SO-101 and Optimus designed to do?+
SO-101: Robotics research, data collection, and policy evaluation. Optimus: General-purpose physical work.
What sensors do SO-101 and Optimus use?+
SO-101: user-configured cameras, joint position feedback. Optimus: vision-based perception.
What software and control options do SO-101 and Optimus support?+
SO-101: Hugging Face LeRobot, Feetech SDK. Optimus: Tesla neural networks. SO-101: leader-arm teleoperation, learned policy. Optimus: autonomous.
Are SO-101 and Optimus the same type of robot?+
No. SO-101 is a fixed manipulator platform; Optimus is a humanoid platform. Direct specification comparisons may therefore reflect different jobs.
