I'm A Senior In High School, A

I'm a Senior in high school, and my school has very little focus on technical classes. I am doing an independent study in which I am creating a robot. I plan on creating a hexapod robot. I will use this to show the other kids, and faculty at my school the cool and attainable things students can do with technology. I intend on making the robot from scratch and will need to control at least 18 servos (for the legs), and possibly a couple more. The body will be 3D printed. It will also have a gyro and ultrasonic sensor for autonomous movement.
