This paper evaluates the dynamic and kinematic properties of a prismatic mechanism and shows its capabilities in performing home manipulation tasks when integrated into a robotic arm. Our design is motivated from the observation that human hand motions often follow a linear trajectory when manipulating everyday objects. We present the mechanical design for a light-weight, energy-efficient robot named...
This paper presents a study on the optimal base location and arm motion of a mobile manipulator for door opening task. Numerical simulation results show that the base location where the manipulability of the two-link arm is almost degenerated at the start and end points of door opening is optimal.We show by analysis that the location has an advantage in supplying kinetic energy to the door by using...
In this paper we present a driving system and control method of newly developed spherical ultrasonic motor (SUSM) as a camera actuator for pipe inspection robot. The pipe inspection robot using SUSM that is very small actuator with three rotational degrees of freedom (DOF) can be inserted to the inside of pipe of 50 mm in diameter. The novel SUSM has improved the range of movement compared to previous...
