Hierarchy of Motor Control01:18

Hierarchy of Motor Control

2.6K
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.

Plotting of Topographic Maps01:29

Plotting of Topographic Maps

39
Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

Design Example: Identifying the Locations of Monuments in the Field Using Global Positioning System Device

27
Surveyors use Global Positioning System (GPS) technology to measure the precise location and elevation of points on Earth. In a recent survey, GPS receivers were used to determine the coordinates and elevations of two park monuments. The process involved careful mission planning, data collection, and correction to ensure accuracy. The survey began with mission planning to identify optimal satellite visibility and minimize Position Dilution of Precision (PDOP). A geodetic control point...

Manipulation and Analysis

23
GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...

Depth Perception and Spatial Vision01:15

Depth Perception and Spatial Vision

612
Depth perception is the ability to perceive objects three-dimensionally. It relies on two types of cues: binocular and monocular. Binocular cues depend on the combination of images from both eyes and how the eyes work together. Since the eyes are in slightly different positions, each eye captures a slightly different image. This disparity between images, known as binocular disparity, helps the brain interpret depth. When the brain compares these images, it determines the distance to an object.

Area of Science:

  • Robotics
  • Artificial Intelligence
  • Human-Robot Interaction

Background:

  • Autonomous mobile robots require intuitive navigation for daily assistance.
  • Current methods often prioritize shortest paths, which may not be optimal for user needs.
  • Flexible path planning with waypoints and real-time inference is crucial for effective robot assistance.

Purpose of the Study:

  • To develop a hierarchical spatial representation and path planning method for robots responding to speech instructions with waypoints.
  • To enable robots to plan improved alternative paths, accommodating detours and user-specified intermediate locations.
  • To integrate semantic, topological, and metric spatial information for enhanced robot navigation.

Main Methods:

  • Proposed a hierarchical path planning method: spatial concept-based topometric semantic mapping for hierarchical path planning (SpCoTMHP).
  • Developed a novel integrated probabilistic generative model with fast approximate inferences across hierarchy levels.
  • Utilized a "control as probabilistic inference" formulation to support the path planning algorithm.
  • Conducted experiments using simulators (SIGVerse) and real robots (Toyota human support robot, Albert) in diverse environments.

Main Results:

  • The SpCoTMHP method demonstrated improved performance over a baseline hierarchical path planning method with heuristic path costs (HPP-I).
  • Achieved a higher weighted success rate (0.590) for reaching targets and passing correct waypoints.
  • Significantly reduced computation time by 7.14 seconds in advanced tasks compared to HPP-I.
  • Successfully navigated using speech instructions with waypoints, such as "Go to the bedroom via the corridor."

Conclusions:

  • Hierarchical spatial representations facilitate mutually understandable instructions between humans and robots.
  • The SpCoTMHP method enables more flexible and efficient language-based navigation for autonomous mobile robots.
  • This approach enhances the practical application of robots in assisting individuals with daily activities.
