Testing edgedetection and communication

Today we tested two things on the actual marslandscape. The Slave brick was equipped with 3 light sensors and communication broadcast ability. The Master brick (shown in front in the attached movie) was equipped with recieving software. This brick will show the status of the Slave brick on its lcd screen. 0 for no edge and an integer if an edge is detected (light1 + light2*2 + light 3*4). Furthermore the Master brick will produce an audible beep when more then 3 packages are lost during communicating. This is simulated by turning off the Slave brick and then turning it back on.
