3D PRINTER USING ROBOT AND CONTROL APPARATUS FOR ROBOT - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240009836 titled '3D PRINTER USING ROBOT AND CONTROL APPARATUS FOR ROBOT

Simplified Explanation

The abstract describes a 3D printer that uses a robot to mold articles with high strength and accuracy. The robot has an input-side encoder that acquires information about the angle of an input axis and an output-side encoder that acquires information about the angle of an output axis. The control apparatus for the robot includes a calculation unit with a control command storage unit, a deviation estimation unit, and a control command correction unit.

  • The 3D printer uses a robot to mold articles with high strength and accuracy.
  • The robot has an input-side encoder to acquire information about the angle of an input axis and an output-side encoder to acquire information about the angle of an output axis.
  • The control apparatus includes a calculation unit with a control command storage unit, a deviation estimation unit, and a control command correction unit.
  • The control command storage unit stores control commands for motors of the robot's axes.
  • The deviation estimation unit receives results from both encoders and estimates the deviation of the actual trajectory of the robot from the control command.
  • The control command correction unit corrects the control command using the estimation result from the deviation estimation unit.

Potential applications of this technology:

  • Manufacturing industry: The high strength and accuracy of the 3D printer can be utilized in various manufacturing processes, such as producing complex and precise parts.
  • Prototyping: The 3D printer can be used to quickly create prototypes with high strength and accuracy, allowing for faster product development cycles.
  • Medical field: The 3D printer can be used to create custom medical devices and implants with high strength and accuracy, improving patient outcomes.

Problems solved by this technology:

  • Lack of strength and accuracy in traditional 3D printing methods: The use of a robot in this 3D printer allows for higher strength and accuracy in the molded articles.
  • Time-consuming and costly prototyping processes: The 3D printer enables faster and more cost-effective prototyping, reducing time and resources required for product development.
  • Limited customization in medical devices and implants: The 3D printer allows for the creation of custom medical devices and implants, improving patient comfort and treatment outcomes.

Benefits of this technology:

  • High strength and accuracy: The 3D printer produces articles with high strength and accuracy, ensuring quality and reliability.
  • Increased efficiency: The use of a robot and the control apparatus allows for faster and more efficient molding processes.
  • Customization: The 3D printer enables customization in manufacturing, prototyping, and medical applications, meeting specific requirements and improving overall outcomes.


Original Abstract Submitted

provided are: a 3d printer using a robot and enabling molding of an article with high strength and high accuracy; and a control apparatus for said robot. a robot used as this 3d printer has: an input-side encoder that acquires information regarding the angle of an input axis of a joint of the robot operated on the basis of a control command; and an output-side encoder that acquires information regarding the angle of an output axis. a calculation unit of this control apparatus has: a control command storage unit having stored therein a control command for motors of respective axes of the robot; a deviation estimation unit that receives results of detection by both of the input-side encoder and the output-side encoder and estimates the deviation of an actual trajectory of the robot from the control command; and a control command correction unit that corrects the control command by using the estimation result by the deviation estimation unit.
