Q1. Move l, move j mean in robot
Ans. 
In robot programming, 'move l' and 'move j' are commands used to move the robot to specific locations or positions.
• These commands are used in robot programming languages to instruct the robot to move to a specific location or position.

• For example, 'move l 10, 20, 30' could instruct the robot to move to coordinates (10, 20, 30) in its workspace.

• Similarly, 'move j 1' could instruct the robot to move to joint position 1 i
