CPM AnchorBot

The CPM AnchorBot is a RC buoy is 11” in diameter and 10” in height. A high visible removable 9.5” bright high visibility orange cone can be placed on top. The mark body and lid are white but can be painted to aid in additional visibility if desired. The AnchorBot comes fully built and only need a 2.4ghz Rx and you are ready to go. Cost is $350.00 plus shipping.

 

For Tx setup a 6CH radio is needed. I use my boats radio (Spektrum) and set the AnchorBot as another model and just switch between them.

NOTE -
It has been brought to our attention that you cannot change between models on the FlySky Radios wthout turning off the first model so unless you are using the FlySky Radio as a dedicated Radio for the AnchorBot you will need another radio system like the Spektrum or Futaba that allows changing between models wothout turning off the first Model. I use an older model Spektrum DX8 Radio to contol all four of our AnchorBots and just switch between models.


Steering is set to the right stick (Like rudder on your sailboat)

Thruster is set to the left stick ( the Thruster is more powerful than needed so only a little thrust is required to get the buoy to really move).

A two-position switch (usually on the top left of your Tx) is used to engage and disengage the winch motor. This also allows the anchor to drop.

A three-position switch is used to winch the anchor. Operation of the switch is

Down position winches the anchor up

 Middle position Locks the anchor

Up position will reverse and let the winch line out (this feature is rarely used)

         

CPM AnchorBot Winch in action

To operate AnchorBot you drive to the desired location using a single steerable thruster. Once in the desired location release the anchor lock and drop the anchor. Once the Anchor is down you lock the anchor off and can turn off the Transmitter and the buoy will go into sleep mode.

To reposition the AnchorBot, winch the anchor weight off the bottom a few feet and drive the buoy to the new location, drop the anchor to the bottom and lock in place again.

When done sailing, winch the anchor off the bottom and once clear you can start driving the buoy back to the dock. There is a micro switch on the bottom of the bot that will stop the anchor winch once the anchor is fully retracted.

In supper buddy bottoms I will watch the bot as the anchor is winched in as the winch is strong enough to pull it under water so when the bot start to get low in the water I turn off the winch and them to flotation of the buoy pull the anchor free and resume winching once clear. For super deep water and to prevent the anchor from burying itself deeply in the mud I will pull out some of the anchor line so the anchor has less distance to fall.

 Attached are some photos and videos. The winch video is of one of the protypes that had two thrusters but this configuration was found to be difficult to drive so we when with the single thruster configuration.
