Luke's Workshop is the first puzzle players are presented with in LEGO Star Wars: The Skywalker Saga's Episode IV. As most players are still learning the basics, many early puzzles require Free Play, but this one only requires you to return after going a bit further in the mission. Once you have R2-D2 and C-3PO, you can complete this puzzle.
How to solve Luke's Workshop Puzzle in LEGO Star Wars: The Skywalker Saga
The first thing you need to do is grab the glowing battery on the wall. The battery is a bit high, but Luke can double jump. Plug the battery into the slot next to the big door, and a Gonk Droid will appear.
The Gonk Droid will tell you that it cannot get to the oil bath if you talk to it with C-3PO. Its stubby little legs won't allow it to get into the bath without a ramp. Turn around and destroy everything close to the Force User item.

Eventually, you'll be able to create a ramp out of the remaining parts. Once you build the ramp, the Gonk Droid will be able to walk to the oil bath.
Then, get R2-D2 to walk to the one spot in the room asking for him, next to the broken droid. After you finish the mini-puzzle, the machine will repair the last droid. Because of the ramp, the droid will automatically go into the oil bath, and all three will be lowered into it.
Once the puzzle is completed, the Kyber Brick will appear.
