Purpose/Goal

  • Build a land-based vehicle that detects and avoids objects
    • Use an ultrasonic sensor to detect objects
    • Use a positional rotation servo to swivel ultrasonic sensor
    • Use 2 continuous rotation servos to move vehicle
    • Use MIT AppInventor and Bluetooth to create a controller for manual use
