stopping it leaving. Go down one, left one, down two, up one, and and drop the bomb. Go down as far as possible. Get the glass piece and go back to the room that had bombs, now only having one. Put the glass piece in the transformer, get the yellow bot and place it in the transformer too, making a glass bot. Go back up to the lazer blocking the exit, and put the bot on the left hand side of the exit. Leave.
Wow, four spoilers for one level. If you still don't get it, I`ll print screen it. xD
...the security bot at the bottom should now only have one block infront of it, thee to the side, and one above. Go back to the room filled with bombs and pick up another bomb. Go back to the room with three security bots. Go as far right and up as possible. Go one right, and place the bomb, so it is diagonally right from the lowest security guard. Leave the room when it is placed. When you're standing on the floor tile outside the door, go two right and up as far as possible, making the security bot move up. Then go back down, and re-enter the room with security bots. There should only be one block on the very left side. Push it up twice, so it stops the security bot from escaping. Push the box on the right one space to the right. Go back to the room filled with bombs and take another one. Go back to the room with security bots and keep to the left hand wall, going as far as possible. Go right one, and them up another, bringing the security bot next to the block...
...put it into the transformer blocks (to the right). Go and get the yellow bot from the north, and bring it to the room filled with bombs. Use it on the other transformer block, making a bomb bot. Put this bomb bot on the tredmill on the right (so it will go into the next room with the security bot). Grab another bomb (it doesn't matter which) and put it in the transformer block, along with another yellow bot, creating another bomb bot. Send it along the same tredmill as last time; going into the room on the right, and blowing up the box in the rightmost room. Take another bomb and go up the tredmil and go into the room with three security bots, lots of boxes and a glass transformer piece. The path you can walk along is only one floortile wide, and six long, four of which are the red colour. Walk onto the second red floortile, and place the bomb (so the bomb is on the third floortile and next to the third box. Move back a few paces before it blows...
