This paper outlines the design of a novel teleoperated robotic system that is proposed for the felling process of Pinus Radiata on steep terrain. The system uses arboreal locomotion similar to that used by monkeys for the method of traversal between trees which has not been used in this manner previously. Machine vision for tree recognition and optimal path planning are used to maximize the efficiency...
The study of quadruped robots is an important branch of robotics. As is known to all, quadruped robots can go through the rough terrain easily and they are useful in field operation. Whether quadruped robot can interact softly with the environment is an important index to value its property. This paper presents the preliminary research of a quadruped robot, mainly focus on the mechanical design and...
Combining teleoperation and haptic feedback is a challenging task. Haptic feedback makes a teleoperation system bilateral, introducing sensitivity to communication system delays. Delays are a common cause of control system instability, but with haptic feedback another source of instability is introduced due to the interaction between force and velocity which adds energy to the system. TCP/IP equipment...
The roll dynamics of a 5kg, 1.3 m high sounding rocket are analyzed in a vertical wind tunnel. Significant turbulence in the tunnel makes the system identification of the effective inertia, damping and asymmetry with respect to roll challenging. A novel method is developed which decouples the disturbance from the rocket frame's intrinsic roll dynamics and allows accurate prediction of roll rate and...
The design and development of an offline self organizing fuzzy controller for a pneumatic artificial muscle (PAM) is discussed in this paper. This inherently compliant soft actuator is intended as the driving component in a mobile, lower limb, assistive/rehabilitative orthotic device. Accurate control using classical control approach is difficult due to the compressibility of gas and the nonlinear...
