Phew! That was amazing! I had a blast at Bay Area Maker Faire building 2020 Bots all day Saturday and Sunday. Once an hour, a couple attendees got a chance to build their own 2020 Bot and take it home with them.
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 […]
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 […]
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
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. Click on each image to download PDF versions:
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 […]
Here are examples of Remote Control and Autonomous modes of the Demo program in the 2020 Bot Library. Remote Control: Autonomous:
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…
The 2020 Bot project is really starting to develop, and it will eventually have a dedicated site. For now, I’ve added a 2020 Bot Resources menu to the blog. You’ll definitely want to check out my project posts along with the resources.
I’ve been using the 3.0 version Arduino Nano on the 2020 Bot, which replaces usual FTDI USB to Serial converter with the less expensive CH340G.
