An electromechanical ladder to raise and lower a step is provided that includes: (i) a front frame, (ii) a collapsible rear frame, (iii) one or more expandable brace members, (iv) a set of two or more wheels, (v) a first hand rail, (vi) a second hand rail, (vii) a first function button, (viii) a second function button, (ix) a first lead screw, (x) a second lead screw, (xi) a compartment, (xii) a reversible motor, (xiii) a sprocket, (xiv) a first drive chain, and (xv) a second drive chain. The step couples in between the front frame and the collapsible rear frame. The one or more expandable brace members prevent the collapsible rear frame from getting collapsed. The set of two or more wheels allow a user to carry the electromechanical ladder from one place to another. The first hand rail and the second hand rail provide a support to the user. The first function button raises the step up when the user presses the first function button. The second function button lowers the step down when the user presses the second function button. The compartment includes (i) a power button, (ii) a fuse, (iii) a rechargeable battery, and (iv) a printed circuit board. The power button turns the electromechanical ladder ON and OFF. The fuse prevents damage to the electromechanical ladder. The rechargeable battery drives the electromechanical ladder. The printed circuit board includes: (i) one or more resistors, (ii) one or more capacitors, and (iii) one or more relays. The reversible motor rotates in clockwise direction and anticlockwise direction. The sprocket couples to the reversible motor. The first drive chain and the second drive chain rotate in same direction with same speed simultaneously. The first drive chain and the second drive chain rotate the first drive gear and the second drive gear simultaneously in the same direction. The first drive gear and the second drive gear transfer the rotary motion to the first lead screw and the second lead screw simultaneously in the same direction with the same speed.
