For some time I have been searching for a simple solution for an autonomous robot able to navigate long distances and avoid obstacles.
The conditions are as follows:
- the navigation system is compatible and can be integrated with Arduino and Raspberry Pi (I plan to use ROS nodes);
- the price should be under $500;
- the system is functional for large land areas (ranging from 1 to 50 hectares);
- localization with an accuracy of up to 30cm;
- the navigation system can be used with easy-to-buy components (preferably at any online store with DIY components);
All the ideas that come to my mind are around two products: Navio 2 and Pixhawk.
The project below includes everything I need right now. A navigation system and a series of sensors for obstacle detection.
This self-navigating system uses Pixhawk and ultrasonic sensors for obstacle detection. It is a simple, low cost and easy-to-buy components.
