This post presents updates to Blossom, the robot that I developed in grad school.
The result is r0b0, “an aconnect for anything.” The tool is message-oriented middleware for connecting “gadgets” — hardware peripherals like motors or MIDI controllers and software applications like pygame or a camera driver or a server — through “cables” that translate messages between them.
