The word "Robot" comes from a 1920's play titled R.U.R., by Karel Čapek, a Czech writer. The story centers around living creatures made of artificial flesh, rather than machinery, assembled in a factory. "Robot" quickly replaced older words, like "automaton", in science fiction.
To easily sew the leather you need to change the regular needle installed in your sewing machine with a heavy-duty needle. It is because the heavy-duty needles consist of a special tip that helps you easily pierce through the leather.
If you are sewing leather then you must make the stitches longer than the regular ones. Normally people use stitches of about 3.5, but you can choose any length of the stitch but it should be longer than the normal one.
When sewing leather makes sure you don’t use cotton thread, for sewing leather the best thread is nylon or polyester. It is because with cotton thread the tannins of the leather get eroded over time.
Using pins in leather is a very bad choice because as you remove them they leave a permanent hole behind. So, while sewing leather using double-sided tape for holding the pieces together is a great choice.
There are many machines or thread that leaves their mark after sewing, unlike fabric the leather cannot be fixed. So, it is very important to test your machine, thread, tension, and stitch length on scrap leather.
If you want to cut the leather make sure you have a very sharp tool. For cutting straight lines the rotatory cutter is considered the best, and shears are great for cutting tight corners, complex shapes, and curves.
