Real-time cast sensor measurement outputs of a set of cast sensors that each measure a characteristic related to usage of an adjustable removable cast worn by a patient during treatment of congenital talipes equino varus (CTEV) are monitored. A cast usage anomaly relative to a treatment program prescribed for the patient with respect to wearing of the adjustable removable cast is identified according to the real-time cast sensor measurement outputs. Responsive to identifying the cast usage anomaly, real-time corrective treatment feedback is provided to the patient that instructs further and proper use of the adjustable removable cast to improve compliance with the treatment program prescribed for the patient.

A smart interactive toy comprises a shell, an interactive control module, a moving mechanism, and an anti-fall sensing module comprising a first signal sending unit and a signal receiving unit; the first signal sending unit is mounted on the shell, connected electrically with the interactive control module and used for sending a first sensing signal to the interactive control module when the signal receiving unit does not receives a first reflected signal, reflected after the first sensing signal meets an obstacle, in a predetermined time period, so that the interactive control module drives the moving mechanism to stop moving, thereby achieving that the user controls the smart interactive toy to avoid it from falling down a table or into a deep pit, which ensures that the toy can be interacted and is not easy to damage.

Described is a remotely controllable inflatable system. The system includes a base having at least one blower and at least one remotely controllable drive wheel. Notably, an inflatable form is connected with and sealed against the base. Activating the at least one blower causes the inflatable form to inflate. A user can then use a remote-control transmitter to cause the base with inflatable form to drive upon a ground surface.

A self-propelled device can include at least a wireless interface, a housing, a propulsion mechanism, and a camera. Using the camera, the self-propelled device can generate a video feed and transmit the video feed to a controller device via the wireless interface. The self-propelled device can receive an input from the controller device indicating an object or location in the video feed. In response to the input, the self-propelled device can initiate an autonomous mode to autonomously operate the propulsion mechanism to propel the self-propelled device towards the object or location indicated in the video feed.

A projected target location of a handheld object is determined based on applying translation factors, scaling factors, and offsets to a location of a reference element of the handheld object detected by a camera on a two-dimensional plane. The translation factors are determined based on a difference between a calibration location on the plane and an initial location of the reference element corresponding to the calibration location, and serve to shift the location of the reference element to generate the projected target location. The scaling factors are determined based on an estimated length of a user's arm holding the handheld object, and serve to scale the location of the reference element to generate the projected target location. The offsets are determined based on polynomial equations, and serve to extend the distance between the projected target location and the calibration location.

The present disclosure relates to a module-type robot control system comprising: a robot platform including a driving unit which is driven by a control signal, at least one function block which is assemblable and disassemblable on the robot platform and configured to perform a specific function, and a user terminal capable of wirelessly communicating with the robot platform and the function block. According to the system. The user may remotely control the module-type robot through a smart device, or receive related content by receiving data from the robot through the terminal. The user may easily control the robot or receive more diverse customized contents by connection between the smart device and the module-type robot system.

An aeronautical vehicle that rights itself from an inverted state to an upright state has a self-righting frame assembly has a protrusion extending upwardly from a central vertical axis. The protrusion provides an initial instability to begin a self-righting process when the aeronautical vehicle is inverted on a surface. A propulsion system, such as rotor driven by a motor can be mounted in a central void of the self-righting frame assembly and oriented to provide a lifting force. A power supply is mounted in the central void of the self-righting frame assembly and operationally connected to the at least one rotor for rotatably powering the rotor. An electronics assembly is also mounted in the central void of the self-righting frame for receiving remote control commands and is communicatively interconnected to the power supply for remotely controlling the aeronautical vehicle to take off, to fly, and to land on a surface.
