I built a little desk robot that serves me drinks so I don’t have to keep reaching over my electronics (and risking a spill) while I’m engineering. The whole idea was simple: I like having a drink at my desk, but water and electronics don’t mix—especially because “pure” water turns conductive once it dissolves impurities. So I wanted a robot that could roll up, hand me the drink, and keep my workspace safer. For the base, I used the Elegoo Smart Car kit because I wanted something that’s smart, programmable, and loaded with sensors—whether you’re a beginner or more experienced, it’s a really solid platform. Assembly honestly felt like building a LEGO-style robot model because the parts are all in the kit. Then I added my own 3D printed cup holder, because that’s my favorite part of engineering: taking an idea and making it real with a personal touch. On the software side, I used Elegoo’s programming app (instead of my usual Python flow) and focused on line tracking so the robot can recognize when it reaches my desk, plus the built-in sensors help it avoid driving off edges. After a couple funny moments (yes, I forgot about the side switch), I got a full working demo of my new desktop assistant.
