Kerala Students Revolutionize Safety with Innovative Ultrasonic Dog-Repelling Stick

In a world grappling with the persistent challenge of stray animal encounters, a beacon of innovation has emerged from the verdant landscape of Kerala. A brilliant team of six students from the Government Polytechnic College, Pala, Kottayam, has engineered a groundbreaking device: an ultrasonic dog-repelling stick that promises a humane and effective solution to the increasing stray dog menace.

This ingenious invention, developed by Arjun A., Vaishakh S.

Kumar, Akshara Rajeev, Anagha M., S. Athira, and S. Revathy, is born out of a deep understanding of the prevailing public safety concerns. Their motivation was clear: to create a non-lethal method to deter aggressive stray dogs, ensuring the safety of pedestrians, commuters, and children without causing harm to the animals themselves.

The core of this revolutionary stick lies in its sophisticated ultrasonic technology.

It emits a high-frequency sound in the range of 20-25 KHz, a frequency range meticulously chosen because it is inaudible to human ears but profoundly irritating and discomforting for dogs. Upon encountering this sound, dogs are naturally prompted to retreat, effectively creating a safe distance between them and the user.

This innovative approach ensures that the animals are merely encouraged to move away, rather than being subjected to pain or injury.

Beyond its primary function, the stick boasts several thoughtful features enhancing its utility. It incorporates a powerful LED light, offering both white and red light options, which is particularly beneficial for nighttime use.

This dual functionality not only illuminates the path but also adds another layer of deterrence or visibility when navigating dimly lit areas. Weighing a mere 600 grams, the device is remarkably lightweight and ergonomically designed for easy portability, making it an ideal companion for anyone traversing areas prone to stray dog encounters.

Powering this marvel is a rechargeable 12V battery, ensuring sustained functionality and environmental consciousness.

The project, a testament to interdisciplinary collaboration, was meticulously guided by the experienced faculty members Babu T.V. and Binu C.V. from the Electrical and Electronics Department, whose expertise proved invaluable in bringing this concept to fruition.

The impact of this innovation has not gone unnoticed.

The dog-repelling stick garnered significant acclaim, securing the second prize at a prestigious state-level project exhibition, highlighting its potential and relevance. With a patent application already filed, the team and their mentors are optimistic about the future. They envision the commercialization of this device, making it accessible to a wider public and significantly contributing to a safer community environment for both humans and animals.

This student-led initiative stands as a shining example of how local talent and innovative thinking can address pressing societal challenges with simple yet powerful technological solutions.
