Friends.. Colleagues.. when ever we think to make a rowing boat, we instantly Googles net, and astonises while looking in to the mechanisms, one used in RC rowing botas, like an RC bike.. it all are based on complex gear boxes, with pricsise lathe work, and some are equpped with four, six, and some eight servos to activate the rowing mechanism.. so, we soon tired while looking in to it all.. leaving the idea behind.. and some of us, istantly rethinks about some robotic gear boxes and complex mechanisms.. if we carefully study the action of the rowing action we will find some thing common in nature.. a cam mechanism.. its all..
and Mother Nature, gave us all ideas around us, if we thinks.. when i was required to make a landing gear demonstrator of a famous fighter aircraft, in big scale, at beginning i feel it as some tough job.. because when retracted, the wheel must be in a flat position under the belly of the fuselage.. but instantly i realizes, that this mechanism is entirely based on Human Hand.. and i demostrated in front of the Officials.. and worked within hours to complete it.. just like that, a rowing boat mechanism is simple, that if we looks carefully.. the entire action can be achieved by two parrallelly linked cams, with drive beams, or can be with individual cam and drive beams.. :thumbsup:
