The Science Buddies Bluebot Kit contains parts to build four different robots:

However, in each project, the sensors are hard-wired to control the robot's motors. This allows the robot to steer left and right based on input from two sensors, but it does not allow the robot to perform more complex behaviors. For example, it cannot back up and turn around, drive through a pre-planned path, or use multiple types of sensors at once. That is where a programmable microcontroller like an Arduino comes in. You can use the Arduino to take readings from multiple sensors and program how the robot should respond. Can you add an Arduino to your Bluebot kit and design an autonomous robot that can drive around your home? You will need to do some of your own research, prototyping, and testing to figure out how to do this. The suggestions below and resources in the Bibliography section will help you get started. Arduino starter kits like the Science Buddies Electronics Kit for Arduino contain some of the parts you will need for this project.

Career Profile
Have you watched "The Transformers" cartoon series or seen the "Transformers" movies? Both shows are about how good and evil robots fight each other and the humans who get in the middle. Many TV shows and movies show robots and humans interacting with each other. While this is, at present, fantasy, in real life robots play a helpful role. Robots do jobs that can be dangerous for humans. For example, some robots defuse landmines in war-stricken countries; others work in harsh environments like… Read more
Career Profile
Just as a potter forms clay, or a steel worker molds molten steel, electrical and electronics engineers gather and shape electricity and use it to make products that transmit power or transmit information. Electrical and electronics engineers may specialize in one of the millions of products that make or use electricity, like cell phones, electric motors, microwaves, medical instruments, airline navigation system, or handheld games.
