A robot includes an articulated arm; and a base unit to which the articulated arm is operably coupled. The base unit includes: a rotating portion; an actuator mounted on the rotating portion and configured to rotate the rotating portion about a first axis; an arm connector attached to a first portion of the rotating portion. The articulated arm is connected to the arm connector to swing about a second axis; and a rib straddling the actuator and connecting the arm connector to a second portion of the rotating portion. The actuator is located between the first portion and the second portion of the rotating portion.

An arm unit of a transfer robot includes an R-axis motor configured to relatively rotate a second arm with respect to a first arm. The R-axis motor is fixed to the first arm so as to protrude to below an arm axis holding portion of the first arm with an output shaft thereof facing upward. The output shaft is configured to penetrate the first arm from below. The output shaft is fixed to the second arm by a shaft fixing portion.
