Donk and Monk - workings

A video to show Donk and Monk's capabilities and their working mechanism. Donk's rowing action is controlled by a custom built "Electronize" electronic speed controller which speeds up the drive motor when a microswitch is closed. The motor is an MFA 940D motor working through a 100:1 planetary gearbox to give the necessary torque. Steering is conventional with a servo controlling the rudder (despite Monk sitting on it). Only two channels of the 2.4GHz Specktrum receiver are used.

The model was built by Mike Sheppard and is now owned by Peter Taylor, a member of the Solent Radio Controlled Model Boat Club ( www.srcmbc.org.uk ). On water footage was taken at Setley Pond.

Hi Kevinmham. The microswitch is closed by a cam and causes the specially made electronic speed controller to run slower/faster for different parts of the cycle, thus giving the realistic rowing action. The lean of the donkey is caused by the oars pulling him forwards and a spring pulling him backwards. Cheers, Peter T (for SRCMBC)

Very nice. I am building a rc rowboat as well. Your mechanism has made me re-think mine ! Is the small switch used to control the donkey's lean ? Thanks.
