Abstract: The present invention relates to an autonomous omnidirectional drive unit including a chassis (40) defining a front third (41), which contains a first drive wheel (11) with a first gearbox (13), a second drive wheel (21) with a second gearbox (23) coaxial with a horizontal geometric axis (EH), and a battery (30) between same, an intermediate third (42) which contains a first motor (12) and a second motor (22) connected to the first and second drive wheels (11, 21) and a vertical housing (70) between same concentric with a vertical geometric axis (EV); and a rear third which contains at least one caster wheel (50), the first and second motors (12, 22) being controlled by a control device (80) which generates control commands considering the distance (D) existing between the horizontal and vertical geometric axes (EH, EV).
