This Application claims priority from a patent application filed in India having Patent Application No. 202121044210, filed on September 29, 2021 and titled “A MATERIAL LAYING ROBOTIC SYSTEM”
FIELD OF INVENTION
Embodiments of the present disclosure relate to material laying, and more particularly, to a material laying robotic system.
BACKGROUND
Construction is one of biggest industry economically, and most important to support the population explosion. But is also the least automated industry which makes it least productive, and the working environment is dull, dirty and dangerous. In a conventional construction, masonry wall laying is performed manually using bricks, blocks, mortar, adhesive, and the like which makes such an approach slow, time consuming and labor- intensive process. Also, a mason bend about or more than 1000 times per shift and works in a tight, ergonomically challenging condition along with picking, laying block at height, due to such limitations, the block masonry is slow, intensive and inaccurate. In addition to this applying mortar, troweling of mortar, pick and place of bricks or blocks, bending also causes a lot of soft tissue injury and other musculoskeletal injures all over the body of the mason, thereby making the masonry one of the top professions that cause musculoskeletal injuries during work. Also, masonry is a skill full that need more than 1000 hrs of training and due the afore said reason skilled masonry force is decreasing. In order to increase the masonry efficiency, and reduce material wastage. Blocks are being used instead of bricks. The block is CMU, AAC, concrete and are 10-15 time bigger in size and 3-5 time heavier. This makes material handling much harder and challenging during laying of these blocks.
In comparison to the conventional approach, a newer approach uses robots to simplify the process of construction. However, the robots in the newer approach, are bulky and weigh
more the 1.5 tons and lay small brick not large blocks. These machines are big, are attached to some kind of truck, crane or Hydra for shifting from one place to another. These machines are not light and portable and hence can only be used for external construction. These machines cannot be moved from floor to floor or passage thorough doors.
Hence, there is a need for an improved material laying robotic system to address the aforementioned issues.
