Reality check
A demo shows what may be possible. These points help judge whether the product fits day-to-day use.
Works well when
- Predictable delivery, cleaning or guidance routes
- Sites with elevators, doors and handoff rules defined
- Repetitive work where staff can handle exceptions
What to check
- Navigation around guests, children and temporary obstacles
- Charging, cleaning and refilling requirements
- Actual handoff behavior when the route is blocked
Not a magic solution
- A substitute for hospitality and human judgment
- A guarantee of lower labor cost without workflow changes
- A safe choice for an untested public environment
About
B1 is an industrial quadruped with approximately 50 kg weight including the battery. Its official table recommends walking loads within 20 kg and lists an 80 kg maximum standing load. Standing endurance is five hours, while continuous unloaded walking is two hours in ideal conditions. The table also specifies depth cameras, computer configurations and external interfaces. These are platform specifications, not proof that an inspection workflow works without software and sensor integration.
