Successive paint stripping robot versions
In developing the EnvirobotTM, NREC performed requirements analysis,
system simulation, design and engineering, prototype fabrication
and field testing. Facing incomplete and dynamic requirements,
NREC developed three version of the robot with each successive
version delivering more performance, flexibility, and reliability.
The robots were extensively tested over the two-year development
period. This testing included week-long runs of 24 hours per
day using inexperienced operators under real-world conditions.
The NREC team conducted the testing on a specially designed
test wall made up of flat, concave, convex and underside surfaces
and connecting weld beads. Following these tests, the team
participated in field trials at several shipyards and, based
on that experience, implemented a dozen engineering programs
to improve reliability and supportability of the robot.
