Robot

1. A robot comprising:

a base, the base having a groove that is provided at an upper inner part of the base;

an arm rotatably connected to the base, the arm rotating around a rotation axis;

a control board provided in an inside of the base, a processor and a memory being mounted on the control board, the processor being configured to execute a program stored in the memory so as to control driving of the arm;

a power supply board provided in the inside of the base, a voltage conversion circuit being mounted on the power supply board, the voltage conversion circuit being configured to convert an externally supplying voltage to a converted voltage so as to supply electric power to the processor and the memory on the board via electric wires;

a main substrate provided in the inside of the base, the main substrate supporting the control board and the power supply board; and

a rear plate provided on the main substrate, the rear plate being detachably attached to the base so that the main substrate is detachably attached to the base via the rear plate,

wherein the main substrate is plate-shaped and has first and second surfaces opposite to each other, the control board is mounted on the first surface, and the power supply board is mounted on the second surface,

the main substrate extends in a first direction, the rear plate extends in a second direction that is perpendicular to the first direction, and the rear plate is orthogonally provided on the main substrate, and

the main substrate is configured to be slidably inserted into the base via the groove.

2. The robot according to claim 1 ,

wherein the main substrate is disposed along an axial direction of the rotation axis.

3. The robot according to claim 1 , further comprising a rib configured to restrict a posture of the main substrate, the rib being provided on the inner part of the base.

4. The robot according to claim 3 , wherein the rib includes the groove into which the main substrate is inserted.

5. The robot according to claim 1 , further comprising a motor provided in the arm, the motor being configured to rotate the arm.

6. The robot according to claim 5 ,

wherein the robot further includes a driving board configured to drive the motor in response to a command from the processor on the control board, and

the driving board is provided in the arm.

7. The robot according to claim 6 , further comprising a first wire configured to electrically connect between the control board and the driving board,

wherein a length of the first wire is longer than a distance between a first state of the main substrate and a second state of the main substrate,

in the first state, the main substrate is provided in the inside of the base, and

in the second state, the main substrate is removed from the base and is located at an outside of the base.

8. The robot according to claim 5 , wherein a voltage supplied to the motor is 1 V or more and 100 V or less.

9. The robot according to claim 1 ,

wherein the main substrate detachably supports each of the control board and the power supply board, and

the main substrate supports the control board in a first position or in a second position different from the first position.

10. The robot according to claim 9 , further comprising a second wire configured to electrically connect the control board and the power supply board,

wherein a length of the second wire is longer than a distance between the first position and the second position.

11. The robot according to claim 1 , wherein a fan is not provided in the base.
