Problems solved by technology

The power-to-weight ratio of the feeding motor itself is small, and a deceleration mechanism is required, which makes the robot bulky and heavy, and there is noise and pollution when the motor is driven
The driving voltage of the servo motor is also relatively high, which is very unfavorable for the development of robots to miniaturization and household and service industries
At the same time, there are too many components in the driver, which will also lead to an increase in manufacturing costs and a decrease in work reliability.

Abstract

The invention relates to a cylindrical driver based on memory alloy wire driving. The cylindrical driver comprises a support serving as a bearing structure, a spiral spring piece, a memory alloy wire, a tail end stator corresponding to the memory alloy wire, a transmission component, an encoder for output shaft detection and a corresponding control circuit. The invention further relates to a working method of the driver, so that the rotation of the driver is realized by electrifying and heating the memory alloy wire. The noise problem of a traditional driver is solved, the structure is simplified, a robot applying the driver has more opportunities to be developed into a micro and portable type, and a new thought is provided for development of the driver.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a memory alloy driver using a memory alloy wire as a power source and a control method thereof. Background technique [0002] With the rapid development of new technologies, shape memory alloys, as an important smart material, have more and more applications in manufacturing, medical and aerospace fields. Shape memory alloys are easy to miniaturize and automate drives, and have incomparable performance advantages over traditional drives. At present, most robots are driven by feeding motors. The power-to-weight ratio of the servo motor itself is small, and a reduction mechanism is required, which makes the robot bulky and heavy, and there is noise and pollution when the motor is driven. The driving voltage of the servo motor is also relatively high, which is very unfavorable for the development of robots to miniaturization and household and service industries. At the same time, ...
