Reality check

A demo shows what may be possible. These points help judge whether the product fits day-to-day use.

Works well when

Research, teleoperation and embodied-AI data collection
Structured factory or reception pilots
Tasks where a human-shaped workspace matters

What to check

Continuous runtime, fall recovery and battery workflow
SDK, low-level control access and spare-part lead time
Emergency-stop features and supported operating environments

Not a magic solution

A general replacement for a human across unpredictable tasks
A maintenance-free appliance
A guaranteed return based on a demo alone

About

RB-Y1 is a wheeled humanoid-form research platform for teleoperation, manipulation learning and whole-body control. It lists 3 kg payload per arm, 600 mm wrist reach plus the hand, and 24 system DOF including mobility and neck. Its 20-DOF manipulation count is a different scope, not a conflicting total.
