Terms

  • Costmap

    A costmap in robot navigation is a grid that assigns each cell a traversal cost from obstacles and safety margins, guiding planners to safe, efficient paths.

  • GNSS

    GNSS, the global navigation satellite system, gives outdoor robots absolute position and time by measuring signals from GPS, Galileo, GLONASS and BeiDou.

  • Obstacle avoidance

    Obstacle avoidance is the robot navigation capability that detects obstacles near the robot and adjusts its motion in real time to prevent collisions.

  • Occupancy grid

    An occupancy grid is a robot navigation map that divides space into cells, each holding the probability that the cell is occupied by an obstacle.

  • Path planning

    Path planning computes a collision-free route for a robot from its start to a goal, optimizing criteria such as length, travel time, safety or energy use.

  • RTK GPS RTK

    RTK GPS is a satellite positioning method that uses carrier-phase corrections from a base station to give robots centimeter-level position in real time.
