This dynamic duo has created one of the most interesting ideas using two miniature actuators that we've seen - using Twitter.
The TwitterDog System Part I.
The system is made up of four main components:
Both the food dispenser and the doggy door are installed with an RFID chip. The home base is an RFBee radio and an Arduino controller connected to the web which receives and relays information. They considered using a Raspberry Pi but ultimately chose the Arduino because of its price and the compatibility of the system. There is a third RFID chip in the collar, which is worn around the dog's neck.
Two linear actuators were used to help make this project a reality. To lift and lower the doggy door, Javon and Allison selected our PA-14-24-150 compact actuator, one of our most popular items. They were seeking the right speed and the right stroke length for the door.
The second actuator was used to open and close the food dispenser. The small, PA-14-10-150 Mini Actuator was used. This actuator fit perfectly on the underside of the door and gave the kind of accurate control the team was looking for.
When the little furball, or in this case, the little wooden furball, decides it's time to eat, he'll walk over to the food dispenser and trip the sensor. As the door opens, he's presented with a full bowl of food. The food dispenser has multiple bowls that can rotate if your dog keeps coming back for more. Once the pooch has had enough, the door will close and you'll be sent an update via Twitter. This message is relayed to you from the home base. Your dog just tweeted to you. Welcome to 2014.
When it's time to take some fresh air, the dog approaches the doggy door and trips another RFID sensor. The actuator springs into action lift the door and once again, you get a social media update. The future is amazing.
