Through continued research and development, we have improved the KIBO programming block labels to make them easier to scan. All kits sold after November 1, 2017, include the new blocks, but we wanted to make it possible to upgrade the blocks in the older kits.
The Block Sticker Upgrade Pack for KIBO 21 includes all the individual block label stickers and parameter cards needed to upgrade a KIBO 21 robot kit with the new stickers.
You can also purchase stickers for individual blocks “a la carte” here: Block Sticker Upgrade.
