Speed control for quadruped using duty factor

Proceedings. 2000 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS 2000) (Cat. No.00CH37113), 2002
This work deals with the design of a locomotion algorithm that changes the speed of a crawling quadruped by varying the duty factor /spl beta/. The walking pattern used is the well-known wave gait. This kind of gait should be maintained as much as possible since it is the most efficient locomotion pattern on flat ground. However, the transition between

LSTM with Matrix Factorization for Road Speed Prediction

2017
Road speed prediction is a key point of Intelligent Transport System. Plenty of work have proved the effectiveness and efficiency of neural network in forecasting freeway velocity. However, the missing values are obstacles when applying the widely used trajectory data to neural network.

Factors Affecting Walking Speed of Elderly People

Age and Ageing, 1989
Associations between walking speed and other variables have been investigated in a group of 67 women and 58 men aged between 65 and 90 years and living independently. In men, walking speed was related positively to calf strength, step-score (a measure of customary physical activity), hours spent in active leisure, height and weight, and negatively to ...

Environmental Factors Influencing Pedestrian Walking Speed

Perceptual and Motor Skills, 2013
The present study investigated various factors influencing pedestrian speed. Undergraduate students who were registered in psychology courses participated in three studies (Study 1: N = 71, M age = 20.3 yr., 37 women; Study 2: N = 92, M age = 19.6 yr., 48 women; Study 3: N =108, M age = 20.4 yr., 56 women). They were required to walk within the city of

Factors Related to Top Running Speed and Economy

International Journal of Sports Medicine, 2007
The main purpose of the present study was to investigate the relationships between running mechanics, top running speed and economy in young endurance athletes. Twenty five endurance athletes (age 19.8 +/- 1.1 years, stature 1.82 +/- 0.07 m and body mass 69.4 +/- 7.5 kg) performed two separate tests on an indoor track.

Factors That Restrict Speed in Streamline

2010
The fast moving area of mobile telecommunication forces companies to deliver functionality with increasing speed to customers. To deal with these challenges, Ericsson AB cre- ated a software process called Streamline Development(SD); which bridges the gap between long term thinking and agile development.

Factors affecting speed in human‐powered vehicles

Journal of Sports Sciences, 1994
It is shown how to derive the appropriate cubic equation relating power and the effects of friction, gradient and wind resistance on the speed of a human-powered vehicle (HPV). The effects of gradient and wind resistance are explored for parameters representing a typical racing cyclist. The principal conclusion may be summarized as follows: for optimum

Postural factors contributing to reaching speed and accuracy

International Journal of Occupational Safety and Ergonomics
Objectives. Occupational reaching tasks performed with faulty postures may contribute to inefficient movement patterns that could lead to injury. Understanding relationships between posture and muscle activation during reaching tasks may elucidate movement patterns that increase occupational injury risk in workers.

Factors affecting developmental changes in the speed of processing

Journal of Experimental Child Psychology, 1983
Although many studies have found developmental changes in the speed of various processes, they have potentially confounded the subject's age with his knowledge of the task domain and use of strategies. In this study, the strategies used by the subject and his domain knowledge were independently assessed by a number of tasks.
