The Turning Frog kit was not hard to assemble. The Turning Frog is controlled with sound. Some of the components making up the robot include a microphone attached to a variable resistor for controlling sound sensitivity, and two integrated circuit: 4069 hex inverter and 4017 counter. The mechanical parts are small but come together on a wood chassis attached to two gear boxes. When the microphone detects sound, the robot executes four moves in the following pattern: forward, stop, left turn, stop, right turn, stop. I had some help from Marc of Elenco email customer service. I lost two very small parts. Marc had them to me in a few days. In closing, I think the Turning Frog is just as complex as the last three Robots, it was simpler, but just as fun. Watch the video staring: Turning frog and voice by my father. I had fun recording this with him.
