The original robot has only two frontside bumpers. This modified version has two frontside bumpers along to two frontside lightsensors. So this robot can follow a line and react to obstacles in the way the same time.

The solution to the problem of the missing sensorinput on the rcx is very easy: One bumper and one lightsensor share one input. This input has to be configured to handle a lightsensor. Than it's possible to read the bumper as something very bright in front of the lightsensor.

For example, the value of the lightsensor:
| 35  | something black |
| 49  | something white |
| 100 | active bumper   |
