Planning for collision avoidance is essential in any robot application
, but for most single robot cells the ancillary equipment and tooling
remain in fixed and known positions relative to the cell and thus coll
ision avoidance strategies can be planned once only, at the start of p
rogram development. With multiple robot cells not only do the robots h
ave to avoid the tools and furniture of the cell but also one another.
The technology to allow robots to navigate around objects and select
optimum paths is still not as cheap or reliable as would be required f
or use in standard manufacturing applications. Concludes that multiple
robots in the same space can have many advantages and the technology
exists to allow them to work together in an unsynchronized manner, che
cking for collisions before each movement, but that technology current
ly requires considerable effort on the part of robot users to develop
and test their own software.
