Meet the machine that automates the burger-making process

An automated burger machine has been helping to tickle tastebuds in San Francisco.

The bread bun is sliced and toasted before sauces are added. Then comes slices of tomato, onions and pickles.

Finally, the burger pops out on the bun.

During this time, not a single human hand touches the gourmet burger until it's served fresh and hot to the customer.
