Arm Robot

A versatile robot arm system designed and crafted by my hands, thanks to the fascinating world of servos on Aliexpress that caught my attention. This remarkable device boasts four intelligent servos in its upper structure and a diminutive plastic servo controlling the gripper mechanism. Underneath its sturdy exterior lies an Arduino Uno powerhouse skillfully integrated into a discreet base plate concealed within the robot's foundation. Creating this exceptional robotic arm project was, undoubtedly, a delightfully exhilarating adventure.

Before ordering the components, I began constructing a 3D model using their technical drawing on their official webpage, after which I delved into designing the robotic elements with 3D printing in mind. However, at that time, I was not equipped with a 3D printer so my project planning remained speculative, relying heavily on Rhino 3D. Subsequently, my awaited servos arrived, along with a brand-new Flashforge Creator X printer. Assembling the robot necessitated creating the base part in three separate pieces since its original size surpassed my 3D printer platform capabilities. In doing this, I utilised ABS with 10% infill on each segment apart from the topmost piece where I preferred increased sturdiness thus adopting a higher infill rate of 25%. After completing printing the segments, I successfully chemically fused them using acetone dissolved in a yellow container showcased in the video. Furthermore, I took great care in creating an aesthetically pleasing Arduino Uno mounting system for discreetly housing the controller unit within the robot base. When I finally completed testing my servo arm assembly and ensured its operational readiness, I set my focus on developing a precision gripper mechanism which primarily utilised an inexpensive small plastic 9g servo, unfortunately hindering its durability somewhat as it couldn't cope with excessive force and thus tends to break, particularly when closing around items that induce significant torque stress (as plastic gear segments easily come undone) Therefore, considering these setbacks I added a delicate yet powerful microswitch situated adjacent the gripper assembly which automatically intervenes by sensing object detection thus instructing Arduino Uno's control logic to halt turning the miniature motor as evident in the photos. In hindsight this particular issue is something users should pay closer attention during their crafting phase of building this system with flexible material such rubber bands employed appropriately could likely rectify aforementioned defects and improve functionality without major reconfiguration requirements hence opening possibilities to new methods users may come across. Ultimately, my robot stands proud thanks to it taking around 60 US Dollars for acquiring essential components including third party spool filaments I purchased thus leaving no regret in this incredible hands-on challenge of imagination coupled creativity making everything from ground zero which will likely cost any prospective maker the aforementioned price point at an incredibly low budget when accounting actual build expenses incurred along side with numerous time-consuming iterations spent getting my version fully functional. It would mean the world to see how other people handle crafting, operating their robots, as I find true beauty and inspiration by watching fellow artists. So feel encouraged posting links pictures videos if you ever build your robot.
