TECHNICAL FIELD
[0001] The application relates to the technical field of exoskeleton mechanical devices, in particular to a large-arm structure of a teleoperation exoskeleton facilitating fine operation. BACKGROUND
[0002] An exoskeleton is an external support structure, which can be divided into biological exoskeletons and artificial exoskeletons. An artificial exoskeleton in modern technology is a wearable device that enhances human body capacity or assists movement through mechanical, electronic and sensor technologies, and is mainly applied in the fields of medical rehabilitation, military and industry.
[0003] In the prior art, a three-degree-of-freedom exoskeleton upper limb is disclosed in Chinese Patent No. CN202110573711.8, which is provided with mechanical limiters at three rotation angle limit positions to ensure the safety of the wearer. The three-degree-of-freedom exoskeleton upper limb is simple and compact in overall design, and the non-imitative three-degree-of-freedom configuration can greatly simplify the upper limb structure, reduce the weight of the upper limb, and facilitate human-machine collaborative control. Compared with a hydraulic drive, the servo motor drive system is light in structure and has a more rapid control response, which can greatly reduce the complexity of the upper limb structure under the premise of meeting the structural strength, rigidity and operation requirements, and the control method is relatively simple. The large-arm body and the small-arm body are cavity structures with wiring cavities, which are beneficial to the realization of structural lightweight. The servo motor or servo hydraulic system can match the human upper limb movement to the greatest extent, but the relatively complex structure leads to an excessive self-weight of the upper limb, the wearer cannot use it alone without protective equipment, and the upper limb exoskeleton has a low assist efficiency. The adaptability and safety of the wearer are also less considered, and the exoskeleton upper limb cannot meet the use requirements in complex working conditions.
[0004] The applicant finds that the prior art has the following problems in the process of implementing the application: the wearable exoskeleton can restore human action to a greater extent, and the action capture scheme has the advantages of high control precision, simple mapping relationship and high restoration degree of imitative action compared with the former.
