Abstract: This application describes systems, devices, computer readable media, and methods for the function and operation of robotic carts. A robotic cart may include a base component configured for the receipt of a payload, a battery unit, and a mobility apparatus. The robotic cart may include a handlebar component coupled with the base component. The handlebar unit may include a sensor unit configured to transmit a hand detection message when the handlebar unit is grasped by one or more hands and to transmit a force direction message indicating a two-dimensional direction associated with a directional force applied by one or more hands. The robotic cart may be configured to map the area around it and to autonomously move the robotic cart along a path to perform a task.

Abstract: A hardware sensor system comprising a piezo sensor outputting charge data corresponding to a motion, an insulated cable from the piezo sensor to a receiver, to transmit the charge data, an insulated charge to voltage converter on the receiver, the insulated charge to voltage converter converting the charge data to voltage data, an analog-to-digital converter to convert the voltage data to digital data, and an uploader to upload the data to a server for processing.

Abstract: A sleep sensor system comprising a sensor to collect movement data from a sleeper on an adjustable bed, a receiver to send movement data from the sensor to a server. The sleep sensor system further comprising the receiver to receive command data from the server, a bed controller to transmit bed movement command data to the adjustable bed, to cause the adjustable bed to alter one or more settings, and an IoT controller to transmit IoT command data to an IoT device to cause the IoT device to take an action.
