This video shows how to build your own simple steerable robot with a wired remote control. This makes the circuit very easy to build for beginners. You can use a solderless breadboard for easy construction, or solder your circuit to make it more permanent. Written instructions to build the robot are available on the Science Buddies website: https://www.sciencebuddies.org/science-fair-projects/project-ideas/Robotics_p045/robotics/simple-steerable-robot
