Human-Robotic Mimetic Haptic Control Framework
This technology is a method for training a robot to perform the tasks that typically require skilled manual labor with a trowel when installing Exterior Insulation Finishing Systems (EIFS). It measures a human’s motions while using a tool (in this case a trowel), which is then used to teach the robot to perform similarly.
Background:
Exterior...
