Woah hey I haven’t updated since last year. Well here’s a post. Here’s some backstory behind this one: Last time SparkFun had a Free Day, I won $100 after entering a ton of Captchas for several hours and getting lucky. One of the things I spent it on was continuous-rotation servos because I felt like trying to make a robot of some sort. I once tried modifying some regular servos to be continuous-rotation but I pretty much just ruined them, so I don’t want to try doing that again.
In any case, here’s a quick attempt at a simple robot that just moves forward slowly. The wheels were made from parts of a VHS case which were then taped to the servos. I guess the main issue is that it’s USB-powered so it has a really limited range. I tried using a 9V battery to power the Arduino but apparently that isn’t enough to power two servos (I could hear them clicking, but not moving), so I’ll need an extra power source specifically for the servos. The problem is my lack of battery holders.
