“…Rover will reach the destination ,using GPS and in case of signal loss/satellite lock issue, IMU will assist the system to reach the calculated distance towards the next way point, until the GPS locks with the satellite. System developed in [26] caters to the problem of feeding the path manually, while [35] uses navigation system based on IMU (representing the case of GPS signal loss). So a system can be developed using both methods to cater to the GPS signal loss and stated issues.…”

“…Rotary Encoders attached with the wheel are used to estimate the distance travelled to cater to the error accumulation during integration of IMU after every 5 sec. This system is better than simple GPS navigation system [26] as the rover doesn't stop in the middle of the road but continues to move towards the first known point.…”

“…Path feeding is also not addressed as the system uses the path already stored in the code to change which robot is required to bring to dock station, which limits the idea of autonomy in robot. In study [26], developed system uses compass with GPS and application to use navigate along with a differential drive rover. System is more autonomous in nature as it uses the application, but for tracking, different websites are used, which adds delay to the tracking.…”

GPS signal loss is a major issue when the navigation system of rovers is based solely on GPS for outdoor navigation rendering the rover stuck in the mid of the road in case of signal loss. In this study, a low-cost IMU aided GPS-based navigation system for Ackermann Steered mobile robots is presented and tested to cater to the issue of GPS signal loss along. GPS path is selected and fed using the android application which provides real-time location tracking of the rover on the map embedded into the application. System utilizes Arduino along with the node MCU, compass, IMU, Rotary encoders, and an Ackermann steered rover. Controller processes the path file, compares its current position with the path coordinates and navigates using inertial sensor aided navigation algorithm, avoiding obstacles to reach its destination. IMU measures the distance traveled from each path point, and in case of signal loss, it makes the rover move for the remaining distance in the direction of destination point. Rover faced a sinusoidal motion due to the steering, so PID was implemented. The system was successfully tested on the IST premises and finds its application in the delivery trolley, institutional delivery carts, and related applications.
