    Study Notes

    Local Guidance: Search, Beaconing, and Visual Homing

    • The lecture covers three types of local guidance: search, beaconing, and visual homing.

    • Search is used when there is an absence of guidance cues, unpredictable distribution of targets, or when exploring an area thoroughly.

    • Brownian motion and Levy flights are two search strategies that are observed in nature and used by animals, including bees and sharks, to search for resources.

    • Spiral search is a hybrid strategy used by robots without a map of the environment to perform exhaustive search.

    • Beaconing or taxis is directed movement towards an observable cue.

    • Reactive control, such as Braitenberg's Vehicle 2b, can be used for beaconing by positive or negative contralateral or ipsilateral connections.

    • Visual homing is used to move or be aimed towards an imperceptible target with great accuracy.

    • Nico Tinbergen showed in the 1950s that wasps approach their hidden nests using surrounding visual cues, which inspired many homing models for bees, ants, hummingbirds, rats, and robots.

    • The concept of visual homing assumes that visual features will only be perceived at a given position in the visual field from a single location in the environment and the change in position of visual features is predictable across locations.

    • Two methods for visual homing are the average landmark vector (ALV) and image difference functions (IDF).

    • ALV and IDF methods have benefits and limitations, such as good for sparse environments, reducing the correspondence problem, or good for complex environments with no need to detect/match features.

    • Long-range line-of-sight provides long-distance guidance, short line-of-sight requires many memories, and final approach to a specific location requires automated piloting.Biorobotics: Methods and Applications

    • The text discusses the field of biorobotics and its applications in various industries.

    • The authors explore the use of landmarks in navigation, citing studies on honeybees and crickets.

    • They propose the use of the average landmark vector model for navigation without the need for snapshots.

    • The text also discusses adaptive homing, which involves robotic exploration tours.

    • The authors highlight the importance of place memory in crickets and how it can be modeled for robots.

    • The text mentions the use of robots in industrial settings, such as manufacturing and assembly lines.

    • The authors emphasize the need for robots to be able to adapt to changing environments and situations.

    • The text also touches on the use of robots in the medical field, such as in minimally invasive surgeries.

    • The authors discuss the importance of human-robot interaction and the need for robots to be able to communicate effectively with humans.

    • The text highlights the potential ethical implications of using robots in various industries, such as job displacement and privacy concerns.

    • The authors suggest that biorobotics has the potential to revolutionize industries and improve human lives.

    • The text concludes with references to various studies and articles on biorobotics.
