Junior Robotics creators will learn all about the properties of sound while making a Talk Bot that can record and playback sounds. This project explores what sound is and how the Talk Bot’s parts work similarly to the human body. First, the project is assembled, using the step-by-step instructions from the Online Classroom. Once the Talk Bot is built, the creator will have fun recording different sounds and messages, then making the Bot say them back. Then, your Junior Robotics-maker will be challenged to put their understanding to the test by answering some questions and completing exercises.
