Problems solved by technology

[0003] Traditional robots are mostly hydraulically driven, pneumatically driven, and electrically driven. However, considering the shortcoming that the power source of these driving methods is difficult to separate from the body, the present invention designs a magneto-rheological fluid-based robot that can separate the driving power source from the body. The purpose of the spiral drug delivery robot is to overcome the above-mentioned shortcomings of traditional robots, so that the present invention can precisely deliver drugs to target organs or tissues by controlling the robot in the body outside the body.

Embodiment

[0020] like figure 1 As shown, a screw conveying robot based on magneto-rheological fluid includes a head 1, a support part 2, and a screw. There are several screw nodes 5 distributed on the screw, and the screw nodes 5 are distributed on the same surface. The helix is ​​filled with magnetorheological fluid except the helix node 5 , and one side of the head 1 is hinged on the support 2 . like figure 2 As shown, the outer ring of the support part 2 has a magnetic isolation ring, which is used to isolate the external magnetic field. The support part 2 has a radio signal receiver, a micro power supply, a microprocessor and a micro coil inside the support part 2. There is a permanent magnet at the bottom of the head 1. When the robot is in motion, the coil is energized in the forward direction to attract the permanent magnet to the miniature coil. When the robot moves to the specified position, the radio signal receiver receives the instruction signal and the microprocessor proc...

Abstract

A magneto-rheological fluid-based screw conveying robot, comprising a head (1), a support portion (2), and a spiral portion, on which are distributed a number of spiral portion nodes (5), except for the spiral portion nodes (5 ) is filled with magnetorheological fluid, the head (1) is a hollow structure that can be opened, the head (1) is fixed on the front end of the helix through the support part (2), when placed in a rotating and changing magnetic field, the helix rotates Make the robot move forward. In the magneto-rheological fluid-based screw conveying robot of the present invention, the driving power source is separated from the robot body, the volume and weight of the robot are greatly reduced, the structure is simple, easy to control, and the conveying position is accurate.

Description

technical field [0001] The invention belongs to the field of robots, and in particular relates to a magneto-rheological fluid-based screw conveying robot. Background technique [0002] At present, the traditional methods of medication are roughly divided into oral and injection. These two methods rely on the circulation of the blood to deliver the drug to the target organ, but these two methods have certain limitations-it will be degraded by the liver. So in order to maintain the drug concentration, one way is to continue to administer the drug, and the other is to increase the dose. However, blindly increasing the dosage of "the drug is three-point poison" does not necessarily achieve better therapeutic effect, so how to accurately deliver the drug to the target organ or tissue has become an important research content. For example, micro-robots are used as carriers to deliver drugs. [0003] Traditional robots are mostly hydraulically driven, pneumatically driven, and el...
