The inventors Mochizuki, Kenki, Ninomiya, Takeyuki, and Sotobayashi have developed a novel robot design that enables downsizing of the arm. Patent application 20250162136 was filed on November 19, 2024, and posted on May 22, 2025. The design features a first arm, a second arm, and a first motor housed in the first arm, among other key components.

Key Takeaways:

  • The robot design includes a first arm, a second arm, and a first motor, which is housed in the first arm.
  • The first motor includes a first gear configured to rotate around a first axial center.
  • The design features a first decelerator that decelerates rotation of a second gear and transmits the decelerated rotation to a first output shaft.
  • A first brake device is configured to brake the rotation of the first gear and is housed in the first arm to face the first motor.
  • The robot design enables downsizing of the arm by optimizing the placement of the various components.
  • The number of teeth of the third gear is equal to or less than the number of teeth of the first gear.
  • The design includes a third gear that rotates around a third axial center parallel to the first axial center and the second axial center and offset from each of the first axial center and the second axial center.
  • The third gear rotates in conjunction with the first gear at a position separated from the second gear.
  • The robot design also includes a second motor, a second decelerator, and a second brake device, which are disposed in a similar manner as the first motor, first decelerator, and first brake device.
  • The design ensures that the various components do not interfere with each other, even in a bent shape connecting between the first space and the second space.
