Engineering notes and buyer guides for the Prometheus humanoid — imitation learning, vision-language-action models, simulation, deployment, and choosing the right platform.
Collecting Teleoperation Data for Imitation Learning on a Consumer GPU with π0.7
Record teleoperation demonstrations on the Prometheus humanoid and fine-tune a π0.7 vision-language-action policy on a single consumer GPU — cameras, dataset format, and training in one workflow.
Collecting Teleoperation Data for Imitation Learning on a Consumer GPU with ACT
A practical walkthrough: record teleoperation demonstrations on the Prometheus humanoid and train an ACT (Action Chunking with Transformers) policy end-to-end on a single consumer GPU.
Choosing Wrist Cameras and the Mounting Angle for VLA Policies
Why the wrist camera and its mounting angle make or break a vision-language-action policy — how to choose the angle, lens, and setup on the Prometheus humanoid, and keep it consistent across your dataset.
What to Look for When Buying a Humanoid for Research
A nine-point checklist for buying a research humanoid — SDK, URDF, cameras, teleoperation, VLA support, modularity, compute, support, and provenance — with what to ask and why it matters.
Build vs Buy a Research Humanoid: Cost and Time
The real cost and timeline of building a humanoid in-house versus buying one — person-years, opportunity cost, and when each path actually makes sense.
Humanoid Robot vs Robotic Arm: Which to Buy
When a robotic arm is the smarter buy, when a humanoid earns its cost, and how a modular platform lets you start small and scale up without buying twice.
Best Humanoid Robots for Research Labs (2026)
The criteria that separate a research-grade humanoid from a demo unit — an eight-point rubric to evaluate any platform for your lab, with the 2026 landscape by category.
How Much Does a Humanoid Robot Cost?
What a research-grade humanoid robot really costs — the factors that drive the price, the total cost of ownership that is not on the sticker, and how to budget for your lab.
