Our project %#evelopment of Walking !rame for&itting assistance' was an approac" to "elp t"esociety and benefit t"e old and infirm persons forsitting assistance in addition to t"eir walking support(

We "ave presented a very cost effective design wit" avery simple mec"anism to operate( We "ope t"at ourefforts will be beneficial to old and "andicappedpeople( T"is will surely "elp t"em to walk and sit wit"comfort and ease(

)ut still t"ere is a scope of improvement in design infuture as some ot"er cost effective design may beintroduced(
