Abstract: Traditionally, counterweight fork type autonomous mobile robots (AMR) have been used for any kind of pallet. But the challenge is it occupies lot more maneuvering space while making turns, which cannot work in narrow operating zones. Hence fork over AMR is preferred. However, these fork over AMR have extended parts always touching the ground surface and thus are not suitable for pallets with a wooden plank at the bottom of the fork opening in the pallet. To overcome the above technical problems, an Adjustable Counterweight-based Fork Type Autonomous Mobile Robot (ACFTAMR) is provided that includes chassis assembly and vertical mast unit, a horizontal cross slide mechanism and forks. The chassis assembly is provided counterweight assembly and counterbalance shafts that move forward and backward during pickup and release of payload when the vertical mast unit moves in upward/downward direction, thus providing better stability and counterbalance to the ACFTAMR.
