摘要:
[...]the experimental results with seven healthy subjects show the reliability of the novel architecture and the capability to be easily tailored to the user's needs with the chosen robotic device.
[...]Sekine et al. present the development of a shoulder prosthesis based on a hybrid actuation system composed of pneumatic elastic actuators (PEAs) and servo motors.
The paper analysed the gait characteristics with crutches, designed the mechanical architecture, and optimized it using genetic algorithms.
[...]the performance of the final design is verified under many external conditions, such as no-load, gait movement, long-term continuous movement, and load tests.
[...]the actual load on the human back is far less than the payload, which shows that their exoskeleton has good power-assisted effect.
摘要:
The field of robotics offers a wide array of estimation problems, ranging from kinematic and dynamic calibration to pose estimation and computer vision. This thesis presents a set of methods to solve estimation problems encountered in robotics, with an emphasis on industrial robotics. The researched topics are all practically motivated and have found immediate use in applications. Industrial robotics often require high accuracy in the control of the tool posi- tion, applied forces etc. This thesis presents a set of methods to solve commonly encountered estimation problems, including accurate friction estimation, spec- tral analysis of disturbances in electrical motors, kinematic calibration and pose estimation under the influence of high external forces. Common themes among the articles, such as the linear least-squares pro- cedure, are introduced in greater detail in the beginning of the thesis for the uninitiated reader.
