# Horizontal articulated robot

## Abstract

A robot ( 10 ) includes a fixed part ( 20 ), a first arm ( 21 ), a second arm ( 22 ), and a working shaft ( 25 ). The second arm ( 22 ) is longer than the first arm ( 21 ). A protrusion length of the working shaft ( 25 ), which is capable of protruding from the second arm ( 22 ) toward the fixed part ( 20 ) is longer than a distance between the first arm ( 21 ) and the second arm ( 22 ).
