Twin Robots: Ultimate Edition (US)

This is quite easy and can be done on any level. Get whichever is the 1st bot you control right next to the red button on any level and wait for the crusher to come down. (There's a diagram of it's progress on the left)

When it's just over the trapped robots head (you should see a video of the crush about to happen) step on the red button with the robot that's next to it. I waited till I saw the shadow on the crusher and it popped straightaway. I didn't have to escape even though I did.

Have a twin near the red switch but don't hit it. Wait until the other robot is almost dying, and then step on the switch. This one starts at 01:24.

Here's a walkthrough video for all of the achievements:
