Robotic Arm with Computer Vision - Picking Up the Object Idea The main idea behind this project was to create an environment where a robotic arm can execute various commands based on image analysis of a scene. In this article, I will describe each part of the project in detail. For the first task, I focused on detecting and moving a single object. Environment The setup consists of several components assembled together. I used an old table as the base, repainting it white to provide better contrast with the objects. The robotic arm, which I purchased from eBay, is mounted on the middle of the longer side of the table. The arm has six servo motors, including a rotating base and claws at the other end. The parts are made of aluminum and are quite sturdy. Next, I cut and mounted perforated metal ledges to the corners of the table, securing everything together. I then attached an RGB LED strip to the bottom side of the top part of the structure. Finally, I placed a USB ca...

How It All Started I recently received a Raspberry Pi (Model B+) as a gift for my 27th birthday. Naturally, the first thing I did was explore the GPIO (General Purpose Input/Output) pins that can be programmed. I quickly discovered the RPi.GPIO Python library, which supports GPIO manipulation, and I began experimenting with some basic circuits—toggling LEDs, working with an RGB LED, generating speaker beeps, and more. A few months earlier, a colleague had shown me a webpage featuring robotic arms that caught my attention. The closest retailer selling robotic arms was in the Czech Republic, and they only had one model available—the Owi robotic arm. So, I decided to get it and combine it with my Raspberry Pi. Connecting the Owi Arm to the Raspberry Pi The first challenge was connecting the Owi robotic arm to the Raspberry Pi. The model I purchased came with a joystick controller, so I had to figure out how to connect it to the Raspberry Pi. After a few hours of searching, I found a video...
