In that case why can we use these as sensors for our walkers to detect a
moving object other than IR...arent they reliable? and i have an idea of
putting two separate crystal frequency radio in a bicore head or maybe a
photovore for it to detect a object just like the depth perception mode like
when the left side cause some disturbance it will turn to the left to locate
the object and vise versa....i hope this might be considerated
