Capability and evidence map
What each robot is documented to do today.
This matrix separates the capability claim from the strength of the evidence behind it. It avoids treating a sensor, a demonstration, or an optional configuration as proof of a complete autonomous workflow.
Capability status Supported Limited or configuration-dependent Not documented
“Supported” means the maker documents the capability. Each entry identifies its source, configuration limits, and evidence type.

Decision 01 / product model
Optimus is a development program, NEO sells a household outcome, and Unitree sells robotics platforms.
Tesla describes Optimus as a general-purpose autonomous humanoid and is installing dedicated production lines. Its latest investor update assigns the initial builds to training-data collection and functionality development. Tesla has not announced a consumer price, order process, or delivery program, so Optimus is not yet a purchase candidate.
1X presents NEO as a home robot with task scheduling, automatic charging, voice and vision, Redwood AI, and optional scheduled Expert Mode. The ownership or subscription price includes the expectation of an integrated service that continues to improve after delivery.
Unitree presents R1 and G1 as general-purpose humanoids. They can be useful platforms for motion, perception, manipulation, education, and research, but their official materials do not describe a complete consumer chore service. A lab can build toward home tasks, while a household should not assume those tasks arrive ready to use.
Decision 02 / Unitree
R1 lowers the entry price; G1 buys more sensing and runtime.
R1 starts at $4,900 for Air, with a $5,900 standard model and a $10,500 EDU configuration currently listed in the official store. It is shorter and lighter than G1, but its listed runtime is about one hour and its sensing depends on the selected version.
G1 starts at $13,500 and adds a depth camera, 3D LiDAR, and about two hours of listed runtime. G1 EDU expands the joint, computing, hand, and development options. Those gains matter for advanced research, but they do not automatically make G1 a consumer home assistant.
Decision 03 / development
The lowest advertised price is not the developer price.
Unitree's current tables reserve secondary development for R1 EDU and G1 EDU. If custom code, low-level control, simulation, or integration is the reason for buying, confirm the exact EDU configuration and included interfaces in writing before placing an order.
NEO takes the opposite approach. It is a managed consumer system, and 1X does not currently present it as a public robotics SDK. Choose it for the household service proposition rather than for an assumption that its hardware is open to custom development.
Tesla does not currently publish a public Optimus SDK or commercial developer package. Factory training activity and engineering demonstrations do not create a supported external development path.
- Price the exact EDU configuration, not only the base robot
- Confirm included hands, compute, batteries, charger, remote, and support
- Match the SDK, firmware, and simulation versions before development
- Create a conservative physical test and emergency-stop process
Decision 04 / ownership
Space, safety, privacy, and support are part of the purchase.
A biped weighing roughly 27 to 35 kg can fall, collide, or apply force in a room designed for people. Plan a controlled operating area, safe distances, supervision, battery handling, network access, and recovery procedures before the robot arrives.
NEO adds a consumer privacy question because cameras, microphones, connected AI, and optional remote Expert Mode enter the home. Unitree shifts more responsibility to the operator, who must govern sensor data, credentials, remote access, and custom software in the research environment.
Decision 05 / recommendation
Track Optimus, choose NEO for the home proposition, R1 for compact entry, or G1 for the stronger research base.
Optimus belongs on a market watchlist, not a current shopping list. NEO is the most relevant option when the goal is an integrated household humanoid and the buyer accepts preorder risk, remote assistance, and a high early-access price. R1 is the entry point for a smaller Unitree biped, especially when the EDU package fits the project. G1 is the stronger Unitree shortlist when depth sensing, LiDAR, runtime, and broader research configurations justify the cost.
