DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS

[0057] FIGS. 1A through 1C depict front, side, and perspective views, respectively, of a baby walker 100 which comprises a walking assembly, including a plurality of wheel assemblies, and it is equipped with sensors and a controller so as to monitor and control the baby walker 100. The controller is configured to receive signals from the sensors and to control the movements of the baby walker 100. The baby walker is further equipped with a communication module to receive and/or transmit, through radio waves, signals from/to an external device. Accordingly, the baby walker 100 is capable of ascertaining the surrounding conditions, such as proximity of objects, topography of the environment, its position with respect to a starting position or predefined regions, and the presence or absence of the baby inside the baby walker 100. The baby walker 100 is also equipped with braking mechanisms that will substantially slow or stop the baby walker 100 to protect the baby from entering dangerous regions or come in close proximity to objects.

[0058] The baby walker 100 comprises a walking assembly which includes a plurality of wheel assemblies. In this preferred embodiment, the baby walker 100 comprises five wheel assemblies 106, 112, 116, 124, and 134. The walking assembly comprises an upper member 104, a seat 118 which is rotatably coupled with the upper member 104, and a lower member 130 which is coupled with the upper member 104. According to this preferred embodiment, the lower member 130 is coupled with the upper member 104 through five struts 102, 110, 114, 120, and 128.

[0059] In this preferred, embodiment, the baby walker 100 comprises five sensors 138, 140, 144, 146, and 148.

[0060] A proximity sensor is a sensor that can detect the presence of nearby objects without any physical contact. Common proximity sensors emit an electromagnetic field or a beam of electromagnetic radiation, for instance in the infrared spectrum, and detects changes in the return signal. As the object gets closer to the proximity sensor, the signal is increased in value so as to indicate the distance between the object and the sensor. Different types of proximity sensors may be utilized to detect metallic and nonmetallic objects. Such proximity sensors include capacitive proximity sensor, photoelectric sensor, and an inductive proximity sensor.

The optical sensor and the LiDAR sensor may also be utilized to ascertain the location of the baby walker 100 and/or the distance traveled by the baby walker 100.

[0062] The communication module 142 receives and/or transmits radio waves. The communication module 142 maybe the ESP8266 WiFi Module or the HC-05 Bluetooth Module, both available from SparkFun Electronics of Niwot of Colo. The communication module 142 is coupled to and in communication with the controller 136 and can receive coordinates of predetermined regions from an external device. These coordinates along with the position of the baby walker 100 will be used by the controller 136 to determine if and when to apply a brake signal to the wheel assemblies 106, 112, 116, 124, and 134.
