Transformer-type bilateral control has a function to satisfy haptic transmission between the master and slave. However, it has a weakness that the position control limits the movable range of the slave to that of the master in a master-slave system with different configurations. On the other hand, gyrator-type bilateral control has a function that synchronizes the velocity of the one side to the force of the other side. Nevertheless, it has a property that the master and slave position are not controlled. In this paper, the mobile robot is the slave and the pedal robot is the master. The proposed method utilizes the function of gyrator-type bilateral control in differential modal space to couple the tread torque on the pedal to the velocity of the mobile robot. This resolves the restriction on the movable range of the pedal. Simultaneously, a property of transformer-type bilateral control is utilized in common modal space in order to achieve force-based compliance control for the pedal and a feedback of the force information from the mobile robot to the pedal.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125589116","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}

The objective of the controller is to maneuver the MHT towards a desired position with respect to a designated leader. Using the range and bearing of the leader from the robot, the leader-follower controller computes the desired wheel velocities of the MHT to achieve leader-follower formation control. In addition to performing wheeled locomotion to follow the leader, the MHT is capable of using its legs to reconfigure its posture. Thus, moving beyond standard implementations, the leader-follower control strategy presented in this paper is combined with a velocity-based inverse kinematics controller developed in previous work to control the posture of the MHT during leader-follower maneuvers. The results of the leader-follower scenarios implemented in simulation and on the physical MHT demonstrate the robot's ability to execute leader-follower formation control and posture control simultaneously, adding to the versatility of the vehicle to negotiate uneven terrains.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125064499","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}

In laparoscopic surgery, there are some advantages for patients because incision on abdominal wall is small. However, laparoscopic surgery is difficult for surgeons. Therefore, surgical robots with have been studied and developed to support surgeons. Conventional surgical robots have high position accuracy to realize delicate tasks. On the other hand, the transmission of force sensation is inadequate. Force sensation is important information for safer operation. Therefore, a five DoF haptic surgical robot is developed to transmit force sensation to the operator. The mechanism of five DoF surgical robot is suitable for implementing four-channel bilateral control which is one of the methods to transmit force sensation. Particularly, link mechanisms convert the motion of actuators into pitch motion and yaw motion of the end-effector. To control pitch motion and yaw motion precisely, the kinematics of the five DoF surgical robot is necessary. Besides, there is geometrical interference between pitch angle and yaw angle. In this paper, the exact kinematics for the pitch motion and yaw motion is derived. The validity of the kinematics is verified by step response. Then, the performance of four-channel bilateral control with the exact kinematics is verified by the experiments.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"188 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123470352","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}

This paper tackles the above problems and explains structure of the developed device for meal assistance. The newly developed meal assistance device was made by 3D printers for cheap price and customizable. The developed assistance device has two degrees of freedom; translational motion for stab and rotational motion for bringing. In addition, the developed meal assistance device adopted a strategy of polar coordinate-based manual operation, which allows users to operate intuitively. The appearance of the developed device is not heavy compared with the conventional devices shaped like industrial robotic manipulators. Above mentioned features are important and gives competitive power especially in the medical care field requiring adaptation to individual demand.

The structure of the proposed system is based on a resonance ratio control system and a feedback signal of the reaction force response. In this paper, the gain of a pseudo derivation is designed as the feedback gain. From the results of the designed gains, the feedback gain Kf is a negative value. Hence, the resonance ratio control system becomes equivalent to a state feedback. For the stability of the proposed I-PD force control system based on the acceleration control system and a state feedback, a new analysis method is required. This paper analyzes an open-loop of the proposed system considering the bandwidth of the observer. The results of an analysis show that an observer with a wide bandwidth is required. Therefore, the parameters of proposed system using the instantaneous state observer are designed based on the coefficient diagram method. The effectiveness of the proposed method is confirmed by performing numerical simulations based on the model of an industrial robot arm. The results show that the proposed method is effective for the stable force control of an industrial robot arm.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132758236","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}

Traditionally, BLDCs are widely driven by two-level inverters, and they are driven by the pulse-width modulation (PWM). Although high switching frequencies can reduce current ripples by the switching, voltage errors caused by dead-times become large; there are trade-off relationships. In our previous study, it was revealed that multi-level inverters could reduce distortions of torques at optimal frequencies. In addition, voltage errors caused by dead-times can be compensated by using a feedforward compensation or a disturbance observer (DOB). Since modeling errors are remained even if designers manage to tune parameters, perfect compensations are difficult in feedforward compensations. In disturbance observers, although offset values of voltage errors can be compensated perfectly, it is impossible to compensate 6k-th order components. In this paper, an adaptive dead-time compensation is applied for multi-level inverters. Here, a value of a voltage error is estimated by using an observer, and it is used to calculate an adaptive feedforward value. The validity of proposed system is confirmed by simulation and experiments.","PeriodicalId":273847,"journal":{"name":"2016 IEEE 14th International Workshop on Advanced Motion Control (AMC)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128034110","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}

The proposed bilateral teleoperation system has transparency under the presence of time delay. The conventional bilateral teleoperation system cannot have transparency under time delay because the control goals are not clear and inappropriate in the presence of time delay. The proposed method utilizes the position information and the force information of both the master and the slave, and also uses the round trip position and force information. In the proposed method, there are two kinds of structure. The one is Position-Force architecture (P-F architecture), and the other is Force-Position architecture (F-P architecture). These methods achieve a high level of transparency but poorer stability than conventional methods. Therefore, this paper introduces the damping injection, which is famous stabilizing method, into the system to stabilize the system, and analyzes the stability condition of the proposed method without/with damping.
