The Bartendro works a lot like the Inebriator. Both robots dispense ingredients from a series of pumps, following pre-programmed recipes down to the milliliter. There are significant differences between the two though. First off, the Inebriator is based on Arduino while the Bartendro is run by the now popular Raspberry Pi. Second, while the Inebriator uses a moving drink shelf to ferry a glass between its dispensers, the Bartendro simply funnels the pipes from all of its dispensers into the middle. Third, while Inebriator has an onboard LCD control panel, the Bartendro can be controlled remotely thanks to its web app.
But the most important distinction between these two mix masters is that the Bartendro is actually for sale. Pledge at least $249 (USD) on its Kickstarter fundraiser and you get a fully assembled Bartendro; unassembled kits can be had for cheaper. Note that the Bartendro comes in 1, 3, 7 and 15 dispenser variants, and naturally the more dispensers you want the more you’ll have to pay. For instance, the 15 pump version starts at $2,499.
What I like about the Bartendro is that its software and hardware are open source. In fact Party Robotics is encouraging tinkerers to help come up with other uses for their robot. It can be used to mix not just alcoholic drinks but also juice or coffee, and may also be of use in laboratories or factories.
