stair climbing hand trolley

Abstract: A hand truck with the ability to climb stairs would decrease the possibility of injury from having to lift a wheeled cart or its contents over an obstruction. If successful, this device should provide increased safety both in the home and in the workplace. Also, it is hoped that a simple stair-climbing device such as this one might increase public acceptance of other, more complex stair-climbing devices such as wheelchairs.

Promotion of Stair Climbing Exercise in Medical Students to Achieve Physical Fitness with Student’s Normal Routine. -

Abstract: Aims and Objectives: There will be inadequate time for the establishment and perpetuation of physical fitness in medical students. The study was aimed to analyze and compare Physical Fitness in medical students who were staircase climber and non-climber. Methods: The study was conducted on medical students of tertiary health centre of Municipal Corporation Greater Mumbai in 2009. One twenty students (mean age=18.26± 0.695years) were assigned in this study. Study group of(n= 60) students who were regularly climbing 100 steps 3 to 4 times a day for eight weeks and in control group(n= 60) students where nonclimber. Heart rate was found out. Physical fitness index was found out by Harvard’s Step Test. Physical Fitness Index (PFI) was compared by \"Chi-square test in terms of excellent, good, average and poor. Physical Fitness Index (PFI) and resting heart rate was found out by Unpaired \"t\" test. Result: The results of this study have indicated statistically significant (p = 0.000) difference in physical fitness index (PFI) in the climbers group compared to the non-climbers. . Also there was statistically significant (p <0.05) difference in heart rate in the climbers group compared to the non-climbers. Conclusion: The importance of physical exercise like stairs climbing performed regularly helps to improve the cardiovascular endurance in the form of more economical heart functioning. Stair climbing is an efficient, discrete, and well tolerated form of exercise in daily activity.

Object-carrying stairs-climbing vehicle

Abstract: The utility model relates to an object carrying stair climbing vehicle which is mainly and technically characterized in that lower bearing brackets are respectively arranged at the both sides of the front end and the both sides of the rear end of the object carrying stair climbing vehicle, sliding steel plates are installed in the lower bearing brackets at the both sides, and a wide steel plate is installed between centers at the bottom parts of the two sliding steel plates; a front supporting leg with a front wheel at the bottom end is vertically and fixedly installed at the bottom parts at the both sides of the front end of the vehicle frame respectively, a main supporting leg with a main wheel at the bottom end is respectively installed at the bottom parts at the both ends of the wide steel plate, a main supporting connecting rod is connected between the two main supporting legs, and a spring is respectively arranged at the middle part of the connecting rod at the front end of the vehicle frame, and the middle part of the main supporting connecting rod. The object carrying stair climbing vehicle has the advantages of reasonable structural design, and simple and convenient operation, shortcut and labor conservation, and easy storage. The length of the main supporting legs can be adjusted so as to adapt to the height of different stairs or to be used on the flat ground, and the application range of the utility model is expanded.

Real-world large-step stair-climbing for small humanoids using evolutionary computation

Abstract: This paper considers legged robots, in author's case Nao robot, and describes a method for Real-world large-step stair-climbing for small humanoids using Evolutionary Computation. We start by providing background on existing climbing robots and popular methods to make them move, and then discuss the problem of stair climbing robots. Of particular interest is a class of problems, when the robot is not able to pick up its leg on height of one stair of the ladder because of the limitations of its geometrical parameters. We provide a genetic algorithm solution for this task; explain design of the chromosome, forming of initial population, crossover and mutation operations. Results of experiments in the Webots simulator are described. Finally, we describe our experiments with the real robot, and discuss our results.
