Problems and Future Improvements• Problems
• Issue of detecting multiple voices• Each microphone varies in sensitivity• Adding distance between microphones
• Challenge of calculating steps• Constantly depends on position
• Future plans• Add more motor movements
• To limbs or head• Add additional features
• LEDs to eyeballs• Movement in two directions Reverse
direction
Arm movement
Head movement
