Abstract

The various embodiments herein provide a baby walker with braking mechanism to control a movement of the baby walker from moving into dangerous areas. The baby walker comprises a sensor unit, a wave transmitter system, a braking system and a power supply unit. The sensor unit is configured to sense an obstacle in the way of walker. The wave transmitter system, in communication with the sensor unit, is configured to generate signals on sensing the obstacle. The braking system, in communication with the wave transmitter, is configured to control movement of the walker upon reception of signals from the wave transmitter. The power supply unit is configured to supply electric power to the sensor unit, the wave transceiver the braking system.

Claims

a LED bulb configured to indicate on/off status of the sensor unit.

4. The baby walker according to claim 1, wherein a plurality of sensor units are placed on the lower bumper of the walker for enabling maximal detection of the obstacle, wherein a plurality of sensor units are placed at unsafe surrounding places.

5. The baby walker according to claim 1, wherein the sensor unit comprise a plurality of types of sensors, lasers, cameras and a plurality of types of transmitters to maximize the detection of obstruction to the walker, and wherein the plurality of types of sensor units is metering sensor, thermal sensors, color sensitive sensors, subsonic sensors and wherein the plurality of types of transmitters are infrared transmitters, radio transmitters and optical transmitters,

6. The baby walker according to claim 1, wherein the wave transmitter comprises a processor configured to analyze the reflected infrared radiations and estimate a plurality of parameters related to the obstacle and the walker.

7. The baby walker according to claim 1, wherein the wave transmitter transmits a detection signal to the braking system based on a distance between the walker and the obstacle, and wherein the wave transmitter transmits the detection signal to the braking system, when the walker gets too close to the obstruction, and wherein the wave transmitter transmits a second notification signal to braking system when the walker is moved away from the obstruction.

8. The baby walker according to claim 1, wherein the wave transmitter generates a trigger signal to activate an alarm when the brakes are applied to the walker, wherein the alarm turns off when the walker is moved away from the obstacle.

9. The baby walker according to claim 1, wherein the braking system comprises:

a main body for housing a plurality of components of the braking system;
