to the TranslationEngine and so not fixed.

you have to set new position each iteration e.g. using PyRunner

> if it is possible to make the cylinder restart from the initial
position after some iter

yes. You can:
- create a new at original position (and destroy the old one)
- set appropriate state.pos of the cylinder components to match the original position
- set for one iteration velocity and angular velocity such that the cylinder moves to its original position
