I am working on design a mobile robot that should navigate from its initial point to goal point without collision with any obstacles dependent on the Artificial Potential Field algorithm , from my a little bit knowledge , that I will need these components below, please correct to me if there is any additional or shortage components :
1- Two servo-motors (which had encoders) one per axis to determine heading angle and coordinate x-y of mobile robot .
actually this component is the main one should I get , but if there is a specific type you could advise me to buy it , please need your help in this.
2- Five ultrasonic sensors to detect obstacles .
3- H-BRIDGE (Motor Drive Shield) for servo-motors : actually I don't know if I need this component or not but I see many tutorial use these when it has two normal DC motor to control . need your help
4- Arduino UNO kit
5- Batteries : actually also I don't know which type that my work required (4x AA or 6x AA ... etc.)
6- Two capacitors one per servo-motor to help reduce RF noise .
8- Wires and cables for connections
Any help or ideas you offer would be highly appreciated.
