Abstract: A modular sensing device can generate output via one or more output devices. The modular sensing device can include an inertial measurement unit that generates sensor data corresponding to user gestures performed by a user, a wireless communication module, a mode selector enabling the user to select a mode of the modular sensing device out of a plurality of modes, and one or more output devices configured to generate output based on the user gestures and the selected mode. The selected mode configures the manner in which the modular sensing device generates output via the one or more output devices based on the user gestures.

Abstract: An apparatus has a chassis that has a pair of rear wheels that passively rotate and a pair of front wheel sets. Each pair of front wheel sets has an upright with an affixed motor. A front wheel is fixed relative to the upright and engages with the motor. A linkage connects the chassis to each of the uprights and is configured to move the uprights in a first range of motion. A linkage actuator actuates the linkage.

Abstract: A system can include a wearable device and a self-propelled device. The wearable device can include a controller that, in response to a user input on the mode selector, initiates a selected mode from a plurality of modes on the wearable device. The selected mode can cause the controller to establish a communication link with the self-propelled device, and generate an output using a feedback mechanism instructing the user to perform a series of actions with the wearable device. In accordance with the selected mode, the controller can interpret sensor data from one or more sensors to determine whether the user has performed the series of actions while utilizing the wearable device. Based on determining whether the user has performed the series of actions, the controller can generate one of a positive or a negative feedback using the feedback mechanism.
