You’re having a relaxing vacation with your family at the beach and having a nice sunbathe. Suddenly, a strange robot is approaching you. You’re curious and think, “Hmm…, it’s impossible to see a robot in the beach, unless there’s something important mission or secret is going on here!” So, you quickly bounce up from the beach and follows the robot…
Isn’t the above incident sounds like a little bit adventurous for you? Well, guess what! You can make the above fictional story becomes reality, by simply getting yourself into this amazing project, “TB-007 Metal Detector”!
The TB-007 is a smart robot that equipped with a metal detector. You can use it to locate those hidden treasures on the beach, forests or deserts. There’s a wireless camera attached at the front top of the TB-007, which is allowing the user to monitor the bots treasure-hunting progress from the comfort of his deck. Furthermore, the camera is mounted to a servo, and has a Laser pointer attached at the front of the robot for detecting purpose!
By the way, TB-007 is an Arduino based with a motor shield. It has the ability to control the two main motors, including a stepper motor and three servos at once!
The Beat-frequency oscillator is used as the metal detector for the project, due to its ability to detect even the weakest signal!
