The ROVER research vehicle is an example and scaled-down presentation of real vehicles used for research missions on Mars, and is modeled after them with basic functionalities and wireless control.
Wireless control of the vehicle is achieved by a mobile device using BLE communication (Bluetooth Low Energy, which reduces energy consumption) via the Serial Bluetooth Terminal application. The vehicle has a power system consisting of a battery and built-in solar panels that enable system sustainability and extended operation without the need for a wired power supply. The visual display from the rover is provided by a radio camera that can rotate 180° in front of the vehicle. The rover is fully mobile in all directions and can easily rotate around its axis. The drive consists of four wheels driven by small electric motors with transmission. The wheels are designed for precise and slow driving, and the four-wheel drive makes it easier to drive on uneven surfaces.
