a0chptes: In the Power Room with the robot to fix the lens to power up the station, you need to enter a series of colored codes to make the robot get the lens and then to install it. I had to use a walkthrough to know what to enter. Is there any clues that I missed that woulld have told me what the codes were? If not, it seems to me this would be an impossible puzzle. Thanks for any information.
The puzzle isn't really based on the colours, it's about the layout of the control panel. Broadly you can see there are directions for 'Up', 'Down', 'Left', 'Right' and the middle button is 'Grab / Release' The other two buttons (top left and bottom left) delete either the last instruction or the whole sequence.
You chain up a list of commands and then watch the robot perform them by clicking the triangular button on the main screen. Once you've seen how the robot reacts, you can adjust your sequence accordingly.
It's basically a trial and error puzzle. Once you know how the panel works you keep refining the sequence until the robot is able to grab the lens and then insert it into the correct slot. Thankfully the robot won't 'drop' the lens until you have it programmed to do so in the right place - that would have made the puzzle incredibly irritating!
