Let’s face it-raspberry pie The kit can become expensive. But if you have some spare parts, you may be able to build something functional from scratch. Is there no extruded aluminum around? no problem! Maker Fricktorio has successfully used cardboard to create a robotic arm powered by a Raspberry Pi from scratch.
This The best Raspberry Pi project You can make it at home, and this project relies on some easy-to-find materials. Cardboard is used to construct most of the frame and is held together with a little bit of hot glue. It also has a mechanism at the end of the arm that can clamp things made from unfolded paper clips.
The Raspberry Pi used in this project seems to be a 3B+ model. However, the main controller behind the operation is an ESP32 module, which helps the user to control the servo system in the arm by converting the input signal.
ESP32 hosts a web server that users can access to drive the arm. It has several sliders, which can control each servo within a predetermined range. Whenever the user interacts with the web interface, the input is sent to the robotic arm to demonstrate the originality of ripples.
