Embodiment Construction

[0050] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:

[0051] A two-person remote operation training method based on a virtual fixture, comprising the following steps:

[0052] 1) At the master end of the operation, the trainer and the novice respectively control a dual-arm robot through the hand controller, and the slave end is a dual-arm robot. During the operation training task, a two-person dynamic model of the trainer and the novice is established:

[0053]

[0054] in, and i=1, 2 respectively represent the force applied by the operator (coach and novice) to the (left / right) hand controller; and i=1, 2 represent the control power of the operator's left and right hands (trainer and novice) respectively; and i=1, 2 respectively represent the mass model impedance of the driving force of the left and right hands of the operator (trainer and novice), and s is the Laplacian operator; and i=1, 2 repre...

Abstract

The invention relates to a two-person remote operation training method based on a virtual fixture. The guiding force of the virtual fixture is added to the training between the coach and the novice to guide the novice to operate. There is a positive correlation between the deviation degree of the guiding operation, and an inverse relationship between the direction and the deviation, and the evaluation index of the virtual fixture can be adjusted with the training level of the novice. According to the level of novice training, adjust the evaluation indicators of novice training, and update the training process and training intensity in real time.

Description

technical field [0001] The invention belongs to the field of remote operation of robots, and relates to a method for using a virtual fixture as a training evaluation index and using a virtual guiding force for operation training. Background technique [0002] With the extensive application of robots in various fields, the previous way that robots operate according to pre-programmed instructions can no longer meet people's needs, and even in some scenarios, the autonomous work of robots cannot meet people's needs at all. At this time, it is necessary for humans and robots, or even between multiple people and robots to cooperate to complete the operation task, adding human intelligence to the control of the robot. Therefore, it is now faced with the problem of information exchange between humans and robots and operational training among multiple people. Generally, two-person operation training is divided into a trainer and a novice. The trainer refers to the operator with ric...
