Mix Frame Visual Servo Control Framework for Autonomous Assistive Robotic Arms.

ABSTRACT: Assistive robotic arms (ARAs) that provide care to the elderly and people with disabilities, are a significant part of Human-Robot Interaction (HRI). Presently available ARAs provide non-intuitive interfaces such as joysticks for control and thus, lacks the autonomy to perform daily activities. This study proposes that, for inducing autonomous behavior in ARAs, visual sensors integration is vital, and visual servoing in the direct Cartesian control mode is the preferred method. Generally, ARAs are designed in a configuration where its end-effector's position is defined in the fixed base frame while orientation is expressed in the end-effector frame. We denoted this configuration as 'mixed frame robotic arms'. Consequently, conventional visual servo controllers which operate in a single fra
