comment Can't get EV3 to work with touch sensors
Please provide a screenshot of the EV3 program. I suspect the sensor port number is the problem. The EV3 does some work in the background to get this to work automagically.

comment Robot that searches for lights
One light sensor pointed forward suggests that the robot should at regular intervals, stop turn right, turn left, and compare those light sensor values and compare to make sure the robot is still headed in the right direction. Start with just that. Spinning in a circle and finding the brightest value would be a next step.

"two light sensors to rotate my motors"? I'd suggest using just one light sensor and getting that to work before jumping to two.

Is the light sensor pointed forward?, down?, on a turntable?

revised Programming RCX in 10.9 environment
RCX was often run with RoboLab software. 10.9 and 10.4 are versions of OS X (Apple).

NXTs can jump to the latest version of EV3 software. That version is downloadable from Lego.

comment Are there any additional robo center downloads for the nxt-g software?
Are you asking what happened to the NXT software robot plans? The ones that were animals, humans, machines, or vehicles? One my pc, there is one animal, a scorpion. It is located at file:///C:/Program%20Files%20(x86)/LEGO%20Software/LEGO%20MINDSTORMS%20NXT/engin‌​e/EditorVIs/Academy%20Content/activities/animals/scorpion/01/slide-inst.html

comment NXT Brick will not update firmware
"click, click ..." is a sign the firmware has gone bad or has never been installed. So replacing the firmware is the only option. "Port B motor drives at full speed." Does anything else work? LCD panel visible? Can you download programs? Any chance the Port B wiring connection has crossed up wires? If the LCD panel is visible, there are a set of menu options to View the Rotation sensor on Port B. Does that change when the Port B motor is turned by hand?
