According to the embodiments described herein, system and methods for determining relative pose of materials handling vehicles in an industrial environment may include utilizing ultra-wideband (UWB) antenna array systems respective mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles, determining one or more fields of each materials handling vehicle, and determining one or more overlapping fields between the materials handling vehicles based on the determined one or more fields and the relative pose. A vehicle control may be implemented based on the determined relative pose and the overlapping fields as a field enforcement, such as a control action to avoid collision between the vehicles.

Systems and methods for relative pose determination and field enforcement of materials handling vehicles using ultra-wideband radio technology

According to the embodiments described herein, system and methods for determining relative pose of materials handling vehicles in an industrial environment may include utilizing ultra-wideband (UWB) antenna array systems respectively mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles, determining one or more fields of each materials handling vehicle, and determining one or more overlapping fields between the materials handling vehicles based on the determined one or more fields and the relative pose. A vehicle control may be implemented based on the determined relative pose and the overlapping fields as a field enforcement, such as a control action to avoid collision between the vehicles.

A method is provided for Bluetooth Low Energy (BLE) communication between a remote control device comprising a peripheral BLE device and a controller on a materials handling vehicle comprising a central BLE device. The method comprises: polling via a plurality of connection requests, by the central BLE device, communicated with the peripheral BLE device with which the central BLE device is paired. The peripheral BLE device comprising one or more activatable switches. Based on the status of the one or more activatable switches, the peripheral BLE device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one of a first or a second communication operating mode. When operating in the first communication operating mode, the peripheral BLE device replies to only a portion of the plurality of connection requests, wherein each reply message is indicative of the status of the one or more activatable switches.

Power savings for remote control device

A method is provided for wireless communication between a wireless remote control device comprising a peripheral device and a controller on a materials handling vehicle comprising a central device. The method may comprise: polling via a plurality of connection event requests, by the central device, communicated with the peripheral device with which the central device is paired, the peripheral device comprising one or more activatable switches. Based on the status of one or more activatable switches, the peripheral device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one communication operating mode of the peripheral device, wherein each reply message is indicative of the status of the one or more activatable switches. Calculating, by the central device, a number of missed messages.
