There are two LED devices: the LED head and the LED box. Both should be able to run the same code. Visualization software can be found in the LED-box repo.

LED head

The LED head is a dome mounted on top of the robot and acts as its head. The LED dome will be able to visualize simple face expressions and the MEA data stream. The dome uses an arduino communicating with the onboard Pioneer LX computer to control the LEDs.

LED box

The LED box is a standalone device and is not a part of the robot. The box can visualize the MEA data stream and is used at events and display stands. The box uses an arduino communicating with a laptop to control the LEDsThe LED-dome displays animations and visualizes neural activity.
