  • Publication number: 20220266105
    Abstract: A personal mobility vehicle configured to be operated in multiple modes is provided. The personal mobility vehicle operates in multiple modes to address multiple needs in a single all-in-one solution. With an omni-directional wheel and folding frame, the personal mobility vehicle can transform into a stand-up scooter, sit-down wheelchair, trike, push-assist cart, or autonomous robotic vehicle, yet is still compact and portable. The personal mobility vehicle also integrates with the user's smartphone to provide affordable, advanced functionality such as autonomous tracking and navigation utilizing the embedded computer vision and artificial intelligence capabilities.

  • Patent number: 8635011
    Abstract: A system and method for controlling a vehicle in response to the presence of one or more vehicle boundary. According to various embodiments, a system is provided that automates end-turns and sequence execution in real-time based on approaching boundaries. In various embodiments, no pre-planning is required once boundaries and a turn pattern have been defined. Once these items are defined, the system creates end-turns based on what type of boundary is approaching and the turn path prescribed. The system determines what vehicle functions to execute based on pre-recorded sequences and executes the turns and the sequences automatically based on the location and speed of the vehicle and its relationship to various boundaries.

  • Patent number: 8209075
    Abstract: A method and system for controlling a vehicle comprises a boundary establisher for establishing a boundary of a work area. A vehicle position sensor (e.g., a location-determining receiver) determines a position of the vehicle. A planner module plans a raw turn of a vehicle to be executed in accordance with a model turn pattern if the position of the vehicle has traversed the boundary. An adjustment module may adjust the raw turn of the vehicle to a compensated turn such that an implement coupled to the vehicle follows an implement path that substantially tracks the model turn pattern.

  • Patent number: 8204654
    Abstract: A boundary definer or data processor establishes an outer boundary of a work area and defines an offset between an inner boundary and the outer boundary. A reference path module or data processor defines a primary reference path with a target angular heading within the work area. The reference path module or data processor generates secondary reference paths spaced apart from and generally parallel to the primary reference path. An incident angle estimator estimates an incident angle of incidence of the vehicle with the outer boundary. The former or data processor establishes an inner boundary point spaced apart from the outer boundary by the offset and coextensive with a corresponding one of the reference paths. Further, the former or data processor interconnects the established inner boundary points to form the inner boundary.

  • Patent number: 7739015
    Abstract: A system and method for controlling a vehicle with a sequence of vehicle events. A user interface allows the recording of vehicle functions that are being manually executed. After the vehicle functions are entered, they can be saved as a sequence and named appropriately. Once saved, the operator can choose to edit the sequence functions or distances to make adjustments or shift the entire sequence in time. The saved sequence can be executed at a certain distance relative to a boundary being crossed by the machine. The boundaries themselves may be pre-defined in the system, and the system can determine when the boundary is crossed based on real-time GPS position and speed measurements from the vehicle. Error distances can also be measured on the ground to determine what type of sequence shift is needed for fine-tuning. As the vehicle speed is adjusted, the sequence can be continually tuned to allow the sequence to execute accurately in a variety of operations.
