It would be easy to lift a lid with a motor and pulley hoist, and a line fastened to the lid. A stepper motor would be better, for precise positioning. The greater challenge would be lowering the lid.
Raising and lowering the lid of a saucepan, for example, where the lid fits rather precisely inside a ring or over a rim, multiple times, would be a challenge with a hoist system like I suggest above.
servocity.com has linear servos you could use to ensure mechanical alignment, especially if you use a slightly oversize flat lid, but how do you avoid catching the gecko on the down stroke? Maybe lower the lid very slowly? It sounds like a very fun project!
My Linux Simple I/O Library https://github.com/pmunts/libsimpleio has support for controlling DC motors and servos, including bindings for C++ and Python.
