Robot and robot system

A robot comprising:

• a robot main body that includes a base and a robot arm that is rotatable with respect to the base;
• a drive unit that is disposed inside the robot arm and drives the robot arm;
• a wiring that is disposed inside the robot arm and electrically connected to the drive unit;
• and
• a drive board that is disposed inside the robot arm and drives the drive unit,
• wherein the robot arm includes a casing including a main body and a cover detachably connected to the main body,
• the drive unit includes a first pulley, a second pulley having a hollow hole, a belt connecting the first pulley and the second pulley, and a motor that generates a driving force for driving the robot arm and rotates the first pulley or the second pulley by the driving force,
• the wiring includes an insertion area inserted through the hollow hole of the second pulley and an intersection area intersecting with the belt as seen in a direction along a rotation axis of the second pulley,
• the intersection area is positioned between the belt and the main body,
• the drive unit is attached to the main body, and
• the drive board is attached to the cover.

A robot system, comprising:

• a robot that includes
• a robot main body that includes a base and a robot arm rotating with respect to the base,
• a drive unit that is disposed inside the robot arm and drives the robot arm, and
• a wiring that is disposed inside the robot arm and electrically connected to the drive unit;
• and
• a control device that is provided separately from the robot and includes a control board and a power supply board for supplying electric power to the control board,
• wherein the robot arm includes a casing including a main body and a cover detachably connected to the main body,
• the drive unit includes a first pulley, a second pulley having a hollow hole, a belt connecting the first pulley and the second pulley, and a motor that generates a driving force for driving the robot arm and rotates the first pulley or the second pulley by the driving force,
• the wiring includes an insertion area inserted through the hollow hole of the second pulley and an intersection fixture intersecting with the belt as seen in a direction along a rotation axis of the second pulley,
• the intersection area is positioned between the belt and the main body, and
• the main body is provided with a first fixture which serves as the fixture and is disposed inside the belt and a second fixture which serves as the fixture and is disposed outside the belt, as seen in the direction along a rotation axis of the second pulley.
