CMC reviews how pulleys work and the different types of mechanical advantage systems, from simple to complex. Learn more at cmcpro.com.
The theoretical mechanical advantage of a system is the ratio of the force that performs the useful work to the force applied, assuming there is no friction in the system. In practice, the actual mechanical advantage will be less than the theoretical value by an amount determined by the amount...
The main objective of this proposal is to take advantage of the unidimensional tolerating approach for a simple application. In fact, most cases in industrial design deal with analysis and synthesis of unidimensional tolerances. For these cases, the inherent simplicity of the proposed algorithm can ...
Another advantage is that the motors, which drive the ankle, can also be mounted in the thigh when the knee is driven by a ball screw. Compared to other robots with actuators mounted on joint axes, our knee and ankle motors are mounted on the thigh to raise the CoM of the biped and ...
例如,建筑起重机就是这样一种机器。起重机一般只使用三种简单的机器。杠杆、滑轮和液压缸。 杠杆 在这篇文章中,我们将简要地研究建筑起重机中一个非常重要的机构:杠杆。而随后的三篇文章,将分别研究滑轮、液压缸和机械优势的概念在建筑起重机中的作用。
For example, for the DC motor version, and taking advantage of the fact that force is proportional to the current through the motor, a Hall Effect sensor 1024 (FIG. 10) can be used for measuring motor current, with its output inputted along path 1024a to the main microcontroller 1000 (...
The main advantage of the proposed new design is related to the increased mobility of the shoulder. However, such joint requires a different design of the compliant actuation. Therefore, the here mentioned solution is still under evaluation. Additional work is devoted to design a passive ergonomic...
