Fish Feeder Robot

The aim of the system:

In fish farms, as in other facilities for raising animals, there is a daily routine of feeding the fish in ponds and containers. The work is demanding in terms of complexity and manpower requirements. There is often a need to distribute different quantities and types of feed to the different pools depending on the type of fish, their age, weight and number of fish in each pond. The quantity and composition may change from time to time. In order to provide fish with optimum growing conditions, it is necessary to distribute the food throughout the day at regular intervals. Calculating these parameters requires work and accuracy in the feed's delivery. Crystal Vision's robotic feeder replaces hand feeding and allows the grower to determine, in advance, the amount, number of feedings during the day and the type of feed provided to each tank according to the demands of the growth cycle. The system expedites maintaining tank hygiene, health and aids in developing an optimal growth chart. The robot can serve as a platform for additional puposes such as distributing artemia, additives or medications. Future Versions will include an additional digital imaging system which will document the growth and progress of the school in each pool. The system maintains a record of the amount of food given to each pool and, in so doing, affords the grower a tool to use in analyzing and improving production and savings in valuable food and manpower.

Description of the system and its parts:

  1. Fish Feeder Robot is an integrated system including a central computer and a robot for automatic feeding. The robot travels along its own independent track. Each robot has a fully automatic battery charging station and a food refilling station, from which it begins its feeding route.
  2. The robot has its own self-contained power source. It feeds the individual fish tanks according to a predetermined program set by the grower. A rail runs above the tanks and a passive transmitter (RFID) over each tank relays the address of that specific tank. According to the location, the robot "knows" what the feeding program is for that particular tank.
  3. The robot distributes the feed to the tanks in predetermined portions, according to the desired type of food. Each robot comes with three separate feed containers and it is possible to add more.
  4. At the end of a feeding cycle, the robot comes to rest at the charging station and waits for the next feeding cycle.
  5. The robot's feeding containers may be filled once a day or automatically using an auger.
  6. The system calibrates the specific weight of each type of feed in order to achieve a highly accurate portion.
  7. The feeding regimen is managed by a unique program and designated operating screens offering the operator complete control of food quantities and feed times. The interface is user friendly and comfortable to operate. The program stores information and produces graphic reports as needed.

The system includes:

  1. A central computer capable of wireless communication with several robots. Each robot includes a controller, feed containers, a propulsion system, RFID receiver, rechargeable batteries, a charging circuit and a wireless transmitter for communicating with the central computer.
  2. A suspended rail for the robot, the path of which can be varied to pass over the pools.
  3. A battery recharging station.
  4. A warning system which sends text messages in the event of a fault.
  5. Service and the guarantee of Crystal Vision.
