Forces acting on foot soles during stair climbing in healthy probands and in patients with coxarthrosis

Abstract: UNLABELLED We investigated the contact forces acting on the sole of the foot of healthy persons and coxarthrosis patients climbing and descending stairs. The sole contact forces were determined using an experimental set-up comprising a stair construction provided with an integrated measuring step. RESULTS In healthy subjects, the forces acting on the soles of the feet while climbing stairs were found to be 1.2 times their body weight. With regard to descending stairs, a distinction must be made between "hard" and "soft" walkers. In the case of "hard" walkers, the forces acting on the soles may be as much as 2.6 times body weight. These forces can be reduced by the wearing of shock-absorbing shoes. CONCLUSION In coxarthrosis and prostheses-bearing patients, all movements are executed more slowly when climbing or descending stairs, so that only small dynamic forces arise. The greatest loads are about 1.2 times the patient's own weight. In these patients, an effective reduction by shockabsorbing footwear is not possible.

Design and Implementation of a Cable Driven Lower Limb Exoskeleton for Stair Climbing

Abstract: To assist the disabled people, the exoskeleton systems have been developed in robotics. As a result, such systems have absorbed a lots of interest in recent years. One of the main challenges of developing exoskeleton systems is their perfect design. In the present study, to help the elderly people a lower-limb exoskeleton is designed and fabricated which assist them for stair climbing. To this end, a conceptual design of such a wearable robot is presented. Simulation of the system is performed in ADAMS and its effectiveness was shown. In addition, a prototype of the system is manufactured to show the performance and functionality of system in some stair climbing trials.

Research on Fuzzy PID Control of Physical Exercise Supporting Robot Speed Control System

Abstract: Physical exercise assisted robot speed regulation has higher requirements on dynamic characteristics of the system and faster response speed, and there are many uncertain factors in the process of climbing athletes in the process of climbing the building. Single closed-loop negative feedback control based on traditional control strategy System speed regulation is unsatisfactory. Based on the above problems, this paper establishes the mathematical model of the fuzzy PID control system of the physical exercise assisted robot speed control system, and designs a double closed loop speed control system based on fuzzy PID, and compares it with the traditional PID control; The sprint speed is given to the sinusoidal speed given curve by referring to the stability of the elevator climbing process and the comfort of the occupant. Using Matlab simulation, the simulation results show that in the physical training robot speed control system, the fuzzy PID control is more stable than the traditional PID control start and braking process, with higher comfort, smaller error and higher precision. Stair climbing has a strong use value and brings good value to the economy and society.
