Abstract:

The automation of tasks in construction industries is a solution for countries experiencing a labour shortage in those industries. The task of drywall finishing in an off-site construction environment is particularly interesting for automatization because of the large amount of labour, the strain on the worker’s body, the falling risk and the large quantity of dust particles. This article explores assisting workers with drywall finishing using an arm-mounted orbital sander with a collaborative robot arm placed on a mobile platform, combined with a drywall joint compound machine vision detection algorithm. Preliminary results suggest the robot can finish the same depth of material as a human worker, which is typically less than 0.19 mm.
