2.4 Environment
dynamic X, Y, Theta, size, and path-planning information with each other. AMRs then factor
this data into their obstacle avoidance. This is not a physical method of preventing collisions,
such as interlocked gateways or barriers. Ultimately, it is the end-user/integrator's respons-
ibility to provide a physical method of preventing collisions.
IMPORTANT:
When two AMRs approach each other directly, neither can prop-
erly determine the other's physical size. Their lasers scan several inches into the
other's laser slot, returning an incorrect distance estimate. Because of this, any
installation that has two or more AMRs working in the same operating space
must be managed by the same Fleet Manager.
NOTE:
Software-based means of collision avoidance are not safety rated. Care
should be taken to control traffic flow using map features, and apply proper soft-
ware-based clearances. It is the user/integrators responsibility to evaluate if hard-
ware methods of collision avoidance are necessary for the application or
operating space. These could include physical barriers or interlocks in the oper-
ating space that are specific to your application.
Traffic Control
A "switchable forbidden area" can be programmed on the map to prevent the AMR from enter-
ing an area based on the state of a discrete input. If this input is set from another vehicle, such
as a forklift, while it is in that area, then the AMR will not be allowed to enter that area.
Passing Lanes
Since the LD Platform Cart Transporter technology does not use fixed tracks to guide the
AMRs, the concepts of passing lanes and human safety areas are not relevant.
2.4 Environment
General Environmental Conditions
It is the end-user’s responsibility to ensure that the operating environment of the platform
remains safe for the platform. If there are areas that are not safe for the platform to travel in,
those areas should be physically blocked off so that the platform’s scanning laser will detect
the barriers, and the platform will not attempt to drive there. These areas can also be blocked
off with forbidden zones in the MobilePlanner software, but that should be in addition to phys-
ical barriers.
Public Access
The LD Platform Cart Transporter is designed for operating in indoor industrial or pro-
fessional environments. It must be deployed in a manner that takes into account potential
risks to personnel and equipment. The product is not intended for use in uncontrolled areas
without risk analysis, for example, areas open to general public access. Use in such areas may
require deployment of additional safety measures.
