IBL-26-0623Method and apparatus for implementing a parallel processing algorithm for real-time path generation of high-degree-of-freedom robot manipulators
Implementation Method of Parallel Processing Algorithm for Real-Time Path Generation of High-Degree-of-Freedom Robot Manipulators

This technology is a path post-processing algorithm that determines optimal, collision-free joint configurations in real time by parallelizing the search for all possible joint combinations across multiple sub-paths, thereby efficiently improving the manipulator's motion trajectory.

Existing adaptive partial shortcut (APSC) techniques sample and select a fixed number of joints during iterative path refinement, which leads to increased computation time as iterations grow and makes it difficult to respond to dynamic environments.

This technology divides the manipulator's motion path into multiple sub-paths and performs parallel computations on all possible joint combinations for each sub-path to select and apply the optimal configuration in real time, maximizing path refinement efficiency. Applicable to logistics transport, service robots, and autonomous platforms, it reduces total computation time and enables parallel processing in dynamic environments, improving path generation efficiency for high-degree-of-freedom robot manipulators.

Key Features:
  • Determining sub-paths from the existing path and initializing each sub-path
  • Determining all possible joint combinations for each sub-path
  • Performing parallel path refinement for each joint combination to generate improved sub-paths
  • Replacing existing sub-paths with those that provide the greatest path refinement effect

This invention was developed with support from the Ministry of Science and ICT's Human-Centric CPS research program.

IBL-26-0622Floor finishing installation system using autonomous robots
Autonomous Floor Finishing Installation System

This technology is a system where multiple autonomous robots (for coating, loading, transporting, installing, and charging) collaborate to install floor finishing materials. It features precise positioning using 3D localization devices and active markers, as well as a high-precision installation mechanism based on vision-sensor-driven obstacle avoidance and floor surface recognition.

Relying solely on manual labor for the transport and installation of increasingly large and heavy construction materials results in low work efficiency. Existing remote-controlled robots are limited by the operator's line of sight, making fine adjustments difficult, and the high rate of human error on construction sites poses significant safety risks.

This technology establishes an autonomous robot swarm control system. A 3D localization device transmits positional data to the robots via active markers, while a manipulator structure—combining floor-sensing sensors and vertical/horizontal arms—precisely installs finishing materials according to the floor's coordinate system. By improving the efficiency and safety of material installation on construction sites, this system can also be adapted for rehabilitation training, gait assistance, and various medical and welfare services.

Key Features:
  • 3D localization device that recognizes the position and orientation of multiple active markers installed on the job site using vision-integrated distance sensors
  • Vertical arm attached to one side of the horizontal arm, operating in an up-and-down motion to install floor finishing materials
  • Work-oriented vision sensor mounted on one side of the vertical arm for moving and installing floor finishing materials
  • Multiple floor-imaging sensors that recognize the shape of the floor surface where adhesive has been applied to a uniform thickness

This invention was developed with support from the Ministry of Science and ICT for the development of intelligent painting and masking collaborative robots.

IBL-26-0621Series Elastic Actuator
Series Elastic Actuator

This technology is a Series Elastic Actuator (SEA) structure that measures torque and controls rotation angle without changes to the moment arm by utilizing wire tension during relative rotation between a first body (including a motor) and a second body. The wire's center is wound around a pulley seat, with both extended ends connected to preloaded first and second springs and adjustment devices.

Conventional series elastic actuators suffer from difficulties in accurate torque measurement and control because the spring is positioned between the output stage and the link, causing the spring to bend or rotate during deformation, which alters the moment arm.

This technology maintains a constant moment arm by securing the center of the wire to the outer circumference of the pulley and supporting the extended ends through a preloaded spring system within the second body. It establishes a structure that allows for precise control and measurement of wire tension via adjustment devices and a housing design. Applicable to robotic gripping, precision measurement, and automation equipment, it improves torque measurement accuracy and facilitates torque measurement based on external forces.

Key Features:
  • A wire comprising a central portion curved around a seating area, and first and second straight extension portions extending from both ends of the central portion.
  • A pulley configured to rotate about a first rotation axis when the rotor rotates, equipped with a seating area that forms an arc around the first rotation axis.
  • A first adjustment housing accommodating a first spring, a first neck portion, and a first adjustment nut.
  • A first adjustment device coupled to the first extension portion to move in tandem with it.

This invention was developed with support from the Ministry of Science and ICT for the commercialization of immersive human-robot multi-sensory interaction technology.

IBL-26-0612Robot system and calibration method thereof
Robot System

This technology precisely calibrates the position of a robot arm's end-effector by using external sensors to track markers attached to the arm and a fixed reference marker, calculating the error between the robot arm's real-time displacement and the sensor data.

In industrial robotics, calibrating the position of a robot arm often requires cumbersome manual teaching or the input of separate setup devices, and errors occurring during the teaching process have historically made high-precision tasks difficult to perform.

This technology simultaneously senses a ring-shaped first marker attached to the robot arm and a second marker serving as an external reference point using an external sensor unit. By comparing the robot arm's actual operational displacement with the changes in marker position and performing geometric calculations, it derives position calibration values for the end-effector.

IBL-26-0601Calculating Robot Workspace Using the Jacobian
Method for Calculating Robot Workspace Using the Jacobian

This technology provides a geometric method for numerically calculating the workspace of multi-degree-of-freedom robots. It simplifies high-degree-of-freedom robot models into lower-degree-of-freedom models by representing certain links as a single virtual link (pseudo-arm) and applies the Jacobian determinant to determine the boundaries and union of the workspace.

Due to the lack of existing technologies for effectively calculating the workspace of planar robots with 3 or more degrees of freedom or spatial robots with 4 or more degrees of freedom, there are limitations in real-time safety monitoring and collision avoidance control for these robots.

This technology replaces multiple links with a virtual "pseudo-arm" connecting the origin to the end joint. It models the system as a 2-DOF planar or 3-DOF spatial robot based on its kinematic structure and uses the Jacobian matrix to numerically calculate the workspace based on the maximum and minimum length variations of the links. Applicable to industrial robots and automation systems, this method improves operational efficiency and safety by providing a precise way to calculate robot workspaces.

Key Features:

  • Step of assuming the planar pseudo-arm and the nth planar arm are connected in the form of a 2-DOF planar robot
  • Step of calculating the workspace of the assumed planar robot using the Jacobian matrix

This invention was developed with support from the Ministry of Trade, Industry and Energy for the development of functional safety implementation technology and risk assessment/reduction technology based on international standards for robots operating in human-contact environments.

  • e) A step of generating a fourth transformation matrix, which represents the relationship between the coordinates of the distal ring frame and the coordinates of the distal bone fragment, by performing steps b) through d) for the distal bone fragment.
  • a) A step of acquiring a first C-arm X-ray image of the proximal bone fragment, including the proximal ring frame.

This invention was developed through the Ministry of Education's support for fracture surgery navigation via image-based 3D fracture modeling.
