Robot Sentry Duty
Obviously, there’s going to be course error buildup. I don’t think encoders would help that much. I’m thinking of navigation beacons, like so: (Maybe infrared? Hmm . . . . )
Servo Center Location Test
It looks like the climactic scene in a monster movie, Arduino vs. Bot. In reality, this setup enables me to keep the ATMega328 chip on the Arduino while I upload test programs to locate the servo centers. According to the … Continue reading

Mini Grisbot with tabs and slots
Here’s an expanded view of mini grisbot. I tried to learn from previous experience and incorporate design changes accordingly. Indeed, this design is probably going to change as well. Just so we’re clear, minigris is a very small robot:
