Not just a model, a piece of art and an inspiration for us.

@ Anjan - The Avatar action figure is used one; purchased from ebay.
@ Iyer Sir, thanks a lot.

completed this prototype kayak mechanism, more a self tutorial one.

brilliant piece of engineering!!!!! What an Idea!!

Thanks Sreekant, but the credit goes to this Gentleman who designed this mechanism, his final video yet to come :


This is another rc kayak boat.

What is the function of the servo and how is it connected?

Here the Crank performs two functions (1) reciprocating action at the main axle (2) swing action of the main axle.

The swing rod passes though a ball joint, fixed on a perforated strip which in turn controlled by a servo. By changing the position of the ball joint and the lower end of the axle it is possible to steer the boat as shown in the below figure.
