Abstract

An automated drywalling system for applying joint compound or plaster to drywall pieces. The system includes a robotic arm and a mudding end effector coupled at a distal end of the robotic arm, the mudding end effector configured to apply joint compound or plaster to a target surface. The system can further include a computing device executing a computational planner that: generates instructions for driving the mudding end effector and robotic arm to perform at least one mudding task that includes applying joint compound or plaster, via the mudding the end effector, to one or more joints between a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one mudding task.
