Transfer robot

A transfer robot comprising:

• a first arm provided rotatably around a first axis which extends along a vertical direction;
• a second arm connected to the first arm rotatably around a second axis which extends along the vertical direction;
• a posture adjuster connected to the second arm rotatably around a third axis which extends along the vertical direction;
• and
• an arm distal end portion fixed to the posture adjuster and connected to a workpiece holder to hold a workpiece,
• wherein the posture adjuster is configured to rotate the workpiece holder around a first posture adjustment axis which intersects both the third axis and a direction extending toward the arm distal end portion away from the third axis, and
• wherein the posture adjuster is configured to further rotate the workpiece around a second posture adjustment axis which intersects both the first posture adjustment axis and the third axis.
