STEP 15: We built our robot assembly line to build from the left side of the stage. Let's flip it to the right side!

The += operator works with any math operation. We can use -= to decrement (decrease) a value instead.

• Change the values of legs_x, body_x, and head_x from -200 to 200. This will start building on the right side.
• Inside each loop, change the += assignment operator to be -= instead. Remember to change all three!
• Click Run to see the robots built from the left side of the stage! Everything should look the same at the end.
