The original two BottleBots were constructed in the summer of 2005 for a feature in a magazine article on VEX. The challenge then was simple: "design a robot which can grab a beverage off a table, open it, and pour it into a cup." The BottleBots would become two of the most popular robots to come out of the VEX Lab.
Three years later, the challenge remained the same. This time it was Robot Magazine who asked the IFI engineers to improve upon their previous creation and come up with a better BottleBot.
The new IFI intern Tyler Holtzman would use the lessons learned from the original build to design and construct the BottleBot3. This robot included several of the best features from each of the previous BottleBots while incorporating several ways to improve its function. It would be featured in the November/December 2008 issue of Robot Magazine.
