Contribution deal with the measurement of the operating characteristics of the piezoelectric linear motor Linear Piezo LEGS Twin 20N type LT20 and control unit PDM101 both from PiezoMotor. The data processing and evaluation was performed. The motor was tested in a vacuum environment and has been studied primarily precision of positioning (micro-positioning) under different operating conditions.
In generating walking patterns for humanoid robots, a Center-of-Mass trajectory is usually derived from the desired Zero-Moment-Point (ZMP) trajectory. One way to accomplish this is the use of the preview-control method, which tracks the desired ZMP trajectory while minimizing the jerk. Another method, which is more computationally efficient, is based on the convolution-sum method. Although this method...
The walking procedure of the cattle, Bostaurus, on a paddy field before spring plowing was captured with a high-speed video camera. The properties of the paddy soil used for tests and the geometrical configurations of the hooves of the cattle were examined. The geometrical configurations and motion postures of the cattle during walking on paddy field were analyzed, and the gait parameters were gained...
In recent years, various control methodologies are reported in the field of bipedal fast mobility, and some robots succeeded to run. Running motion is the combination of fast walking and jumping cycles. So we proposed a control method based on the idea of manipulating Centor of Gravity (COG) point in real time and succeeded jumping. In jumping experiments on humanoids, Ground Reaction Force (GRF)...
We consider the task of planning smooth trajectories for robot motion. In this paper we make two contributions. First we present a method for cubic spline optimization; this technique lets us simultaneously plan optimal task-space trajectories and fit cubic splines to the trajectories, while obeying many of the same constraints imposed by a typical motion planning algorithm. The method uses convex...
During quadrupedal robot locomotion, there is pitch, yaw, and roll of the head and body due to the stepping. The head motion adversely affects visual sensors embedded in the robot's head. Mammals stabilize the head using a vestibulocollic reflex that detects linear and rotational acceleration. In this paper we describe the use of a machine learning algorithm that utilizes signals from an artificial...
The paper describes a novel approach to control a biped robot for the stable gaits. The target is to achieve to reduce the impact force with the ground when the swinging leg comes into contact with it. In our approach, redundant legs are introduced for the biped, and the decoupling control system are applied, which consists two independent control laws. One of the laws is for the hip position control,...
