There is no out of the box framework in PAD. However, you can try to implement it as per your automation project and yes it will need some effort and time to make it robust.
Framework is nothing but set of rules or guidelines which you follow in order to design your automation scripts/bots. Therefore essential feature would be:
1. Exception handling.( create a try catch as a global error handler and log it).
2. recovery abilities ( You can use on error actions in PAD).
3. Effective logging mechanism.
4. Re-usable ( create subflows )
5. Easy to maintain and handle.
Hope it helps!!
