Solenoid-based and latch-typed brake system for in-wheel module

In this study, we propose a new brake system to be used for in-wheel module of active walking aids. Along with the increase in the aged population, there has been many research devoted on active walking aids, which helps the movement of olds and disabled. In this study, a new brake system with low power consumption is developed to maximize the battery life of active walkers. Through the use of two solenoids, the developed brake only consumes power when it is switching between the on-off states. The performance of the proposed system is verified through various experiments.
