The Equipment

The SlashBot system will consist of three different modules: a real-world interface, a sensing & computing unit, and an actuation component.

Real-world Interface
This component is responsible for producing the video signal and provides an interface to interact with the game (i.e. accepting input from the controller). It also has a monitor to display the video signal on a screen.

Sensing & Computing
Here we designed a system that will digitize the input video signal, use triggers to analyze the signal, and send appropriate control commands to the analog robotic circuit. We are employing a National Instrument PXI system for this processing component. After speaking with National Instruments (NI) representatives, we configured such a system to meet our needs.

Actuation
This is the actual “robotic” portion of the design. Six solenoid actuators will be mounted above the Guitar Hero controller. One for each of the colored input buttons and one for the “strum” bar.
