Many ways are being devised to improve the interaction between humans and machines in the field of robotics. For instance, the existing approaches claim precise control over the robotic arm using many different controllers like the joystick, keypad control, or electroMyographic (EMG) sensors attached to the human arm as separate units. However, it requires a non-practical amount of calibration time and high operational expertise. Therefore, our goal is to mimic the human arm movements on the 6-degree of freedom (DOF) robotic arm in real-time, providing minimum latency. We practically show the interfacing of Myo armband with robots that provide tremendously low calibration time without compromising efficiency. We also allow a 6-DOF using EMG and inertial measurement unit (IMU) signals for Myo armband and extract the values of EMG and IMU sensors. The extracted raw EMG and IMU values are calibrated using Arduino as a standard micro-controller. Due to the extraction of raw values, Myo armband can also be integrated with other users' peripheral, which in our case is a 6-DOF robotic arm.","PeriodicalId":160127,"journal":{"name":"2020 3rd International Conference on Mechatronics, Robotics and Automation (ICMRA)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134092202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cobots work alongside humans to extend the scope of robot assistance to spaces such as service and dynamic industrial or assembly tasks. With that said, the close proximity of humans with machines necessitates safe interaction, which can be achieved via lightweight materials and novel sensing capabilities. The inherent physical strength needed in some robot tasks, such as in assembly, make contact sensing of particular concern when introducing a human collaborator. A minimally intrusive method that can be seamlessly subsumed into extant devices is desired. In this paper, such a contact sensor is prototyped and tested. The sensor is bidirectional in that it actively provides an oscillatory actuation signal to a rigid link while simultaneously recording and analyzing the mechanical vibration of said link. Natural oscillation frequency shifts and energy concentration changes due to damping are congruent with different types of contact with the rigid link. The method is lightweight, low-cost and can be quickly incorporated into various manipulators. The developed configuration is advantageous as it does not require any delicate sensors on the robot body and relies primarily on actuated oscillations of the manipulator. Oscillatory acceleration data is collected and subsequently used to train and classify different contact locations using frequency-based features. Three separate classes are distinguished according to contact location. Results are promising and show excellent classification of both contact and contact location.","PeriodicalId":160127,"journal":{"name":"2020 3rd International Conference on Mechatronics, Robotics and Automation (ICMRA)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117061973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Firstly, the causes and characteristics of the errors generated by the existing minimum jerk model (MJM) in modeling the trajectories of real human arm reaching movements are investigated, and a new motion model called MMJM is proposed based on a 2nd order Fourier modification term.

There are two different moving modes of the reconfigurable wheel, i.e., a wheeled mode and a tracked mode. The wheel can adaptively change the mode of the wheel according to the road conditions. It can move as fast as the ordinary wheels on hard ground. Meanwhile it can perform well on the soft ground and easily climb over obstacles in the tracked mode. Based on the adaptive requirements, the mechanical structure of the wheel is designed. Moreover, the mechanical model of the wheel on the soft ground is established, and the adaptability of the wheel to different road conditions is analyzed. The mechanical model of the wheel in the wheeled mode climbing over a vertical obstacle is established, and the rationality of the wheel climbing over obstacles is verified. The finite element analysis of some key components is conducted to verify the rationality of the design.

Secondly, we develop theoretical models to describe the coupled dynamics of the integrated isolation system that made up of the flywheel and isolation platform. This model can be well used to analyze the dynamics of flywheel isolation system and predict the isolation performance. Finally, we investigate the coupled dynamics and micro-vibration responses of the coupled isolation system using both experiments and simulation methods. Comparisons are conducted between the tests and simulations, and good match is achieved, which means the theoretical model developed in this paper can be extended to applications in flywheel isolation design and analysis.
