Abstract: The embodiments herein discloses a semi-autonomous mobile robotic apparatus (100) that can apply primers and paints and perform other operations such as wall sanding, drawing abstract wall art on the interior walls of buildings. The disclosed semi-autonomous mobile robotic apparatus (100) apparatus comprises of at least 13 numbers of type-1 (403) and at least 2 numbers of type-2 (405) ultrasonic sensors coupled to the apparatus (100), at least 2 Light Detection and Ranging (LiDAR) sensors (401 and 402) coupled to the apparatus (100), a human machine interface module (102) adapted to receive one or more inputs from a user (101) and provide the data to the microprocessor (103) for processing inside the apparatus (100) and provide output to one or more modules (104 and 105) to perform the relevant painting, sanding, putty application or abstract wall art drawing operations.

Abstract: A system for painting an interior wall of housing is disclosed. The system includes a semi-automatic painting robot 106 and a user device 104. The semi-automatic painting robot 106 includes a microprocessor 304, a servo drive module 306, a DC motor drive module 316, a magnetometer 312, a distance sensor module 318, a first servo motor 708, a second servo motor 714, a spray gun 710, and a belt driven linear actuator 804. A user device 104 captures one or more images of the interior wall to be painted, processes and sends the one or more images to the microprocessor 304 in co-ordinates of the interior wall. The microprocessor 304 receives the co-ordinates and performs the operations of painting on the interior wall using one or more painting strokes. The user 102 may control the semi-automatic painting robot 106 with the user interface present in the user device 104.
