Elenco 21-881 Sound Reversing Car
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.
