IROS - Achievement of complex contact motion with environments by musculoskeletal humanoid using humanlike Shock absorption strategy
2012 IEEE RSJ International Conference on Intelligent Robots and Systems, 2012Co-Authors: Yuto Nakanishi, Tamon Izawa, Tomoko Kurotobi, Junichi Urata, Kei Okada, Masayuki InabaAbstract:We have been developing and studying musculoskeletal humanoids. Our goal is to realize more human-like humanoids which can do natural and dynamic motions as well as humans. Especially motions with complex contact with environments, which is jumping, running, catching a ball, and landing on one's hands, etc, are difficult to be achieved by humanoids. To achieve that motions, robots have to absorb Shock Force so as not to break ones' body structures, such as gears, motors, body links and so on. Musculo-skeletal humanoids are suited for these situations, because they can easily have mechanical flexibilit for Shock absorption by adding elastic units, which is nonlinear spring units, to its own tendons. In this paper, we propose Shock absorption methods by musculoskeletal humanoids, which uses its own mechanical flexibilit and simple refle of each muscles based on tension sensor. This strategy is inspired by human's motion control, and it can achieve Shock absorption tasks without any fast sensor feedback controls and any prediction ocntrols used by conventional robots with rigid bodies. We chose a catching a ball task as an example of complex contact motions, implemented the proposed strategy to musculoskeletal humanoid Kenzoh and confirme the feasibility of proposed method by actually catching a ball demonstration.

ROBIO - Development of differential suspension wheeled system for telepresence robot in rural hospital area
2016 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2016Co-Authors: Korn Borvorntanajanya, Pittawat Thiuthipsakul, Suwiphat Chalongwongse, Choladawan Moonjaita, Jackrit SuthakornAbstract:The shortage of healthcare population is spread around the world especially in developing countries. Telepresence robot is an excellent option to solve this problem by telepresence system. For additional, the stability of robot is an importance key to success for telepresence mission. This research presents a differential suspension designed for telepresence robot to make telepresence system is able to reach most places in hospital. Platform was measured the stability of suspension system with teleoperated function and autonomous function in simulated environment. The inertial measurement unit was used to measure stabilization of system. The suspension system is able to improve stability and reduce Shock Force when robot was passing uneven terrains.

THE 250 KILONEWTON PRIMARY Shock Force CALIBRATION DEVICE AT PTB
2020Co-Authors: Michael Kobusch, Thomas Bruns, Leonard Klaus, Michael Müller, Physikalisch-technische BundesanstaltAbstract:A new facility for primary Shock Force calibrations up to 250 kN Force amplitude is presented. Shock Forces are generated by the impact of two airborne cylindrical mass bodies. Two laser-Doppler interferometers simultaneously measure the bodies' dynamic motions on their axes of motion. Traceability of Force is realised by the determination of mass and acceleration.

A case study in model-based dynamic calibration of small strain gauge Force transducers
ACTA IMEKO, 2017Co-Authors: Michael Kobusch, Sascha EichstädtAbstract:Investigations of the model-based dynamic calibration of a small strain gauge Force transducer of high bandwidth revealed new challenges for parameter identification. This paper discusses a more generalized mechanical model of the calibration set-up employed taking account of the transducer’s connection to its mechanical environment at both ends. Based on new experimental sine and Shock Force data, the improved model is studied and its parameters are identified. It is shown that the proposed model is capable of linking the calibration results of both calibration methods to a much better degree. This paper is an extended version of the original contribution to the IMEKO 2015 conference in Prague, Czech Republic.

investigations for the model based dynamic calibration of Force transducers by using Shock excitation
ACTA IMEKO, 2015Co-Authors: Michael Kobusch, Leonard Klaus, Sascha Eichstädt, Thomas BrunsAbstract:Within the scope of the joint research project EMRP IND09 "Traceable dynamic measurements of mechanical quantities", numerous measurements were performed at PTB's 20 kN primary Shock Force calibration device to investigate and validate the approach of a model-based dynamic calibration of Force transducers by using Shock excitations. The tests included several strain gauge Force transducers of greatly differing structural design, size, weight and mechanical coupling. By looking at a few examples, investigated physical models of the measurement set-up and developed data analysis procedures for parameter identification based on measured Shock data are presented and discussed. The models reproduce the dynamic response including the observed modal oscillations of various origins that limit the usable measurement bandwidth. Moreover, these modal oscillations may have an important role for the parameter identification process, which is further discussed. This paper is an extended version of the original contribution to the IMEKO 2014 conference in Cape Town, South Africa.

investigations for the model based dynamic calibration of Force transducers by using Shock Forces
Joint IMEKO International TC3 TC5 and TC22 Conference 2014, 2014Co-Authors: Michael KobuschAbstract:To investigate and validate the approach of a model-based dynamic calibration of Force transducers by using Shock excitations, numerous measurements were performed at the 20 kN primary Shock Force calibration device of PTB. The tests included several strain gauge Force transducers of greatly differing structural design, size, weight and mechanical coupling. Previous studies proved modal oscillations of the measurement setup of various origins that limit the usable bandwidth. Their effect on the modal-based calibration method with its data analysis procedures to be developed is further investigated and discussed in this paper.
