A motor-driven cart includes a manned/unmanned operation change-over switch, first and second electric motors for driving the cart, a handle lever provided to a main body of the cart to be swung to a predetermined angle with respect to a left, right, forward or backward direction, and a device for generating electric signal for steering and for speed control in response to a swing operation of the handle lever. When an operator changes the manned/unmanned operation change-over switch to its manned operation side and the handle lever is placed in its neutral zone, the motors are put in their stopped state. When the operator manipulates the handle lever in the left, right, forward or backward direction to a position outside the neutral zone, the forward or reverse rotational speeds of the first and second motors are increased in proportion to the extent of the swing operation to turn the cart to the left or right direction or to perform the forward or backward speed control. When the operator\s hand is released from the handle lever, this causes the lever to be automatically returned to the neutral zone nearly in the middle of pivotal center by a restoring force of four spring members.

A motor-driven cart comprising: a first and a second motor for driving wheels of said cart; a handle lever disposed on a main body of said cart so as to be capable of being swung by a predetermined angle in selected one of left, right, forward, and backward, and obliquely right and left in both forw
A motor-driven cart comprising: a first and a second motor for driving wheels of said cart; a handle lever disposed on a main body of said cart so as to be capable of being swung by a predetermined angle in selected one of left, right, forward, and backward, and obliquely right and left in both forward and backward directions; means for generating electric signals for steering and for controlling the speeds of said first and second motors in response to an extent of swing motion of said handle lever, whereby said first and second motors are put in their stopped state when said handle lever is in its neutral zone, while when said handle lever is swung in selected one of the left, right, forward, backward and any other desired horizontal directions outside said neutral zone, said first and second motors are increased in their rotational speeds in a forward or reverse direction in response to the direction and extent of swing motion applied to said handle lever so as to carry out speed control of said cart in the selected one of left, right, forward, backward and any other desired horizontal directions; a guide sensor; a sensor for detecting a forward obstacle; and a manned/unmanned operation change-over switch, whereby when an operator changes said manned/unmanned operation change-over switch to its unmanned operation side and puts said motor-driven cart onto a previously-laid route line, said cart can be driven at a predetermined speed along said previously laid route line, and when said forward obstacle sensor detects presence of such an obstacle as another motor-driven cart stopping forward of said route line, said motor-driven cart is stopped at a place spaced apart from said obstacle at a predetermined distance, while when the operator changes said manned/unmanned change-over switch to its manned operation side, said motor-driven cart can run to an arbitrary place away from said route line in accordance with an operator\s swing manipulation of said handle lever.
