Sound Reversing Car Robot Kit

This kit is a low-cost implementation of the common introductory robot that backs up and turns when it hears a sound or hits an obstacle. The kit is quite basic, but because the instructions do not provide soldering instructions, we recommend this kit for someone who has completed at least one previous soldering project.

This Robotic Car is a great introduction to soldering as well as the basics of sound control and mechanical motion.  The car has an electret mic that feeds noise to the control circuitry.  When a loud enough sound (like a clap) is heard it will cause the car to stop moving forward and reverse itself turning slightly left for a few seconds.  Then the car will resume forward motion in a different direction.  You can adjust the circuit sensitivity so that very soft or very loud noises will reverse the motion.

Specifications:

• Power: 2 AA batteries (not included).
• Includes sound activated circuit.
• Circuit board requires solder assembly.
• Unassembled printed circuit board Soldering required.
• Learn motor theory, transistor switching and R/C time constant circuits.
• Changes direction with a loud sound such as a whistle, a clap or when it hits an object, it will then automatically reverse itself for a preset time and then resume its new course.
• Requires basic hand tools and soldering equipment.
