Abstract

With the development of micro controllers and single-board computer technologies, robotic systems can be designed at a lower cost. In this context, a low-cost autonomous mobile robot has been developed in presented study. By adding a variety of systems to the autonomous mobile robot, remotely controlled and steered robot was designed. In presented study, Arduino and Raspberry cards were used for the autonomous mobile robot, which has a four-wheel and tracked structure. Using the Raspberry card and the Pi camera in the robot, the activities around the robot were transferred to the another computer via internet. A Wi-Fi (wireless fidelity) module was used to connect the internet. The Bluetooth module allows the camera to move right-to-left or up-to-down. The GPS (global positioning system) module has been utilized for the robot to act autonomously. With the ultrasonic distance sensor, the autonomous mobile robot can find a new route by overcoming obstacles. The battery can be charged with wireless charging without the need to be charged with a cable in case the battery weakens during movement. This robot can be used in cargo handling, patient assistance, food and beverage service, a relief vehicle in disaster situations. Designed low-cost autonomous mobile robot has distinguished features and presented development phases of robot can assist researchers.

Multifunctional and Low Cost Autonomous Mobile Robot

Abstract

Mikro denetleyicilerin ve tek kartlı bilgisayar teknolojilerinin gelişmesiyle robotik sistemler daha düşük maliyetle tasarlanabilmektedir. Bu bağlamda, sunulan çalışmada düşük maliyetli bir otonom mobil robot geliştirilmiştir. Otonom mobil robota çeşitli sistemler eklenerek uzaktan kumandalı ve yönlendirilen robot tasarlanmıştır. Bu çalışmada, dört tekerlekli ve paletli yapıya sahip otonom mobil robot için Arduino ve Raspberry kartları kullanılmıştır. Robotta bulunan Raspberry kart ve Pi kamera kullanılarak robotun etrafındaki aktiviteler internet üzerinden başka bir bilgisayara aktarılmıştır. İnternete bağlanmak için bir Wi-Fi (kablosuz uygunluk) modülü kullanılmıştır. Bluetooth modülü, kameranın sağdan sola veya yukarıdan aşağıya hareket etmesini sağlamaktadır.
Robotun otonom hareket etmesi için GPS (küresel konumlandırma sistemi) modülü kullanılmıştır. Ultrasonik mesafe sensörü ile otonom mobil robot, engelleri aşarak yeni bir rota bulabilmektedir. Hareket sırasında bataryanın zayıflaması durumunda batarya bir kablo ile şarj edilmesine gerek kalmadan kablosuz şarj ile şarj edilebilmektedir. Bu robot, felaket durumlarında bir yardım aracı olan kargo hizmetlerine yardımda, hasta yardımı, yiyecek ve içecek hizmetlerinde kullanılabilir. Tasarlanan düşük maliyetli otonom mobil robot, ayırt edici özelliklere sahiptir ve robotun sunduğu geliştirme aşamaları araştırmacılara yardımcı olabilir.
