I want to control a robot from the programming language Scratch but I have no clue how to make this happen. For now I'm running Scratch 1.4 on MacOS, and I can control the robot over BTLE using Swift or ObjC, but don't know where to go from here. The robot has a couple of motors (left/right wheels, head) and several sensors.
Do I need to write an extension in Python? A mod? Can I do this with Scratch 1.4 or do I need 2.0 (hating Adobe Air)?
Any useful pointers would be great!
