Load-Sensitive Continuously Variable Transmission for Robot Hands

Robot Finger with Load - Sensitive Continuously Variable Transmission

This paper shows a 99 [g] finger joint that can exert a very strong fingertip force of more than 100 [N]. We have proposed a simple and small load-sensitive continuously variable transmission (CVT), which consists of five links and a torsion-coiled spring. The maximum fingertip force of our previous finger was limited by the mechanical strength of its links and bearings, not by the power of its...

Modeling and Sensitivity Analysis of Full Toroidal Continuously Variable Transmission

Design of Continuously Variable Transmission (CVT) with Metal Pushing Belt and Variable Pulleys

Nowadays, automakers have invested in new technologies in order to improve the efficiency of their products. Giant automakers have taken an important step toward achieving this objective by designing continuously variable transmission systems (CVT) to continuously adapt the power of the engine with the external load according to the optimum efficiency curve of e...

Application of Multi-objective Optimization for Optimization of Half-toroidal Continuously Variable Transmission

Among different goals defined in vehicle design process, fuel consumption (FC) is one of the most important objectives, which significantly has taken into account lately, both by the customers and vehicle manufacturers. One of the significant parameters which impacts the vehicle FC is the efficiency of vehicle's power train. In this paper, a half-toroidal continuously variable transmission (CVT...

Control of a Continuously Variable Transmission System

This paper proposed control strategies for the modern mechatronic Continuously Variable Transmission (CVT) System using three different techniques; The Ziegler-Nichols, Linear Quadratic and Pole-Placement methods. The results of the system responses of the designed control schemes were successfully simulated using MATLAB. Comparing the results showed that controller implemented using the Pole-P...
