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.
Things to note:
I’ve created an Amazon store for items that can be found there. Almost everything is available, except the L-shaped yellow gearbox motors. The items listed on the 2020 Bot Store are things I’ve actually purchased (and from the vendor listed) for the 2020 Bot, or for my own workshop. I’ll try to keep up with any changes if a vendor stops carrying a product. Unfortunately, some of the items are only available for purchase in multiple-quantities, and I’m certain you’ll spend more than $20 cobbling together parts for just one robot.
