Israeli engineers have Packed a vest and a remote control dog sends commands to the animal via vibration. The vest has four vibration motors that are responsible for the actions of the dog, say the authors of the articlepresented at IEEE World Haptics Conference 2019.
There are two primary ways to control an animal using the training and direct electrostimulation of the muscles or other organs. The second method is much more promising, but while it was used sparingly, mainly on small organisms, for example in dragonflies, and beetles. Training is much easier, although not as accurate as direct stimulation. During training, the animal receives the signal, typically voice, performs an action and receives a reward or punishment. This student formed a acquired reflex.
Engineers under the direction Niski Ilana (Ilana Nisky) from the University named after David Ben-Gurion in the Negev, has created a device that allows you to do the same, but by using silent incentives. The system consists of a vest, worn on the dog and the remote, by which the person remotely give commands to an animal. The vest is fastened with four vibration motor with soft styremedlem pads that penetrate through the wool and transmitting the vibration to the skin. They are located on different sides of the vest, left and right in the front and, in the same way, in the back. The vibrator motor is connected to the microcontroller, receiving signals from the console and launching one or the other of the vibration motor.
The developers decided not to correlate commands with specific vibration motor and chose a different scheme. A constant vibration right front vibration motor means the rotation of the dog 360 degrees. The throbbing vibration of the same motor means that the dog must step back. Pulsing vibration in the left front vibration motor shows a dog that she needs to come to the owner. Constant and simultaneous vibration of two vibration motors in the rear means that the dog must lie down.
Engineers have tested the approach on his six-year-old dog,
a cross between a Labrador Retriever and a German shepherd. The developers have chosen
the four actions that the dog has been learned previously, but perform them after
voice commands. Tests showed that the animal has coped with the transition to the new scheme of giving commands. Moreover, during one of the tests the authors randomly gave voice commands and vibration, and the results showed that the dog most correctly executed commands transmitted via the vest: 93% versus 83%.
Previously, engineers have created a device that allows you to control the dog by using simple stimuli. The Japanese offered to give commands to turn the dog using the laser spots on the floor, and the American has created a vest with turn sausage hanging in front of the muzzle of the animal. In addition, in 2016, Honeywell has introduced the vest for dogs dog service, which has a camera, a GPS receiver and a vibrator motor for transfer of commands on the movement in a similar way.
