Stripped screw of battery compartment
The battery compartment of the Roomba 770 has two screws. One of the two screws is completely stripped.
There is no remainder of the original drive slots. I tried putting some rubber sheet between the screw head and the screwdriver tip to increase traction, no result.
I want to access the battery compartment to put in the new battery I bought, as the screw is stripped I have no means of opening it. Everything else is intact. Can I somehow work my way around this? How can I remove the stripped screw? If necessary to buy addtional tools: I do not have much budget for this project.
Tools I own:
BLACK+DECKER Li2000 3.6-Volt 3 Position Rechargeable Screwdriver
Black & Decker 71-081 Double Ended Screwdriving Bit Set, 10-Piece
