Sonar Walking Stick
The ability to aid the visually impaired is a field that has the potential to advance itself with the improvement of technology. Many of these products that assist those in need can cost up to $650, which is an expense that not everybody in need can afford. This means that the technology doesn't get into the hands of all those who need the devices. The sonar walking stick designed in this repor...
متن کاملStick Insects Walking Along Inclined Surfaces1
SYNOPSIS. In the experiments stick insects walk on an inclined substrate such that the legs of one side of the body point uphill and the legs of the other side point downhill. In this situation the vertical axis of the body is rotated against the inclination of the substrate as if to compensate for the effect of substrate inclination. A very small effect has been found when the experiment was p...
متن کاملSmart Walking Stick for Visually Impaired
In order to help the visually challenged people, a study that helps those people to walk more confidently is proposed. The study hypothesizes a smart walking stick that alerts visually-impaired people over obstacles, pit and water in front could help them in walking with less accident. It outlines a better navigational tool for the visually impaired. It consists of a simple walking stick equipp...
متن کاملCoordinated Walking of Stick Insects on a Mercury Surface
Adult stick insects walk on a mercury surface at step frequencies in the range 1-4 Hz with a coordination similar to that found in free-walking adults at their maximum step frequency of 3 Hz. The amplitude of leg movement covers the same range as that found in free-walking animals. The use of a mercury substrate effectively removes mechanical interactions between the legs, showing that such inf...
متن کاملTitle : " Intersegmental Coordination of Walking Movements in Stick Insects
Locomotion requires the coordination of movements across body segments, which in walking animals is expressed as gaits. We studied the underlying neural mechanisms of this coordination in a semi-intact walking preparation of the stick insect Carausius morosus. During walking of a single front leg on a treadmill, leg motoneuron (MN) activity tonically increased and became rhythmically modulated ...
