2020 Bot Motor Control Examples

I just updated the 2020 Bot Arduino Library to include a couple motor control examples: https://github.com/robojay/_2020Bot_Library One uses the delay() function between motions. This is great for ease of understanding, but not so great to use in practice. The delay() function blocks the robot from doing most other tasks until the time expires. The second example […]

IR Proximity Sensing

When you build a robot, it’s nice to have layers of sensors.  You can think of the layers either top down (maybe starting with a 3D laser scanner), or from the bottom up (are my motors stalled?).  Proximity sensing sits on one of the lower layers, and generally is used as “Hey, there’s something near […]

Programming the 2020 Bot

Once you’ve built your 2020 Bot and played around with it a bit, the next step is writing your own programs.  The 2020 Bot uses an Arduino Nano micro controller.  A simple web search will turn up plenty of references.  Here’s a good link to get you started: Official Nano Getting Started guide from Arduino:  https://www.arduino.cc/en/Guide/ArduinoNano

2020 Bot Wiring

Here is a hookup diagram and a wiring checklist to go along with the 2020 Bot video instructions.  The diagram has a couple breadboard locations that are different than what are called out in the video and checklist, but they are functionally equivalent.

DinoBot – circa 1993

This probably qualifies as my first real robot.  Still works after 20+ years. I built it as part of the final project in my grad school Artificial Intelligence course.  The professor made sure I understood the project was a software project, and not to get hung up on the hardware side (fortunately, being an electrical engineer in […]

Yard Bot

What do you do with some scooter chair motors, big casters, and a sheet of MDF?  Make a radio controlled Yard Bot of course! I’ve had the various pieces for this project kicking around for a while. Finally took the time to put them all together.  Just something to play around with…
