摘要 | Adaptation to the operator's intents and the external physical uncertainties is critical to the performances of the human-robot collaboration. In this study, we proposed a control interface that combined the electrical impedance tomography (EIT) based sensing approach with the robotic controllers to produce proper assistance with external uncertainties in the collaborative task. The interface first estimates the continuous forearm muscle contractions (represented by the grasp forces) by the optimized EIT features with an easily worn fabric band. The recognition decisions then serve as the control inputs to adjust the state transitions and the desired interaction forces in real time. We evaluated the interface in the tasks of grasp force estimation and human-robot sawing by recruiting more than 20 subjects in total. For grasp force estimation, the interface produced an average of R-2 >= 0.9 in both offline and online validations with the feature optimization procedure and a sigmoid regression function. The interface was robust to external disturbances without retraining or manual calibrations. The average R-2 = 0.86 with the untrained dynamic postures, and the average R-2 values ranged from 0.85 to 0.88 in the tests with redonning the front-end in interday and intraday uses. For human-robot sawing, the interface accomplished the tasks with a high success rate in controlling the states (>96%) and intuitive adjusting of the sawing forces, being combined with the designed hybrid admittance/position controller. It was also adaptive to the sawing frequency changes and the sawing directions according to the operator's intents. The interface's performances are comparable, if not better, to the state of the art on both biological signal based grasp force estimation and human-robot sawing. Future efforts are worth being paid in this new direction to get more promising outcomes. |
