The invention belongs to an electric walking device, and more particularly relates to a remote-control spherical electric manned car. The electric manned car consists of a spherical shell (1), a vehicle-mounted instrument (8), a control main board (6) and a storage battery (7), wherein, the middle of the interior of the spherical shell (4) is provided with a circular supporting disk (2), a plurality of groove-shaped ball mounting tube fixed bases (2-5) are fixedly arranged at the edge under the supporting disk (2), and ball mounting tubes (2-1) are fixed on the mounting tube fixed bases (2-5)by using locking nuts (2-6), movably arranged the right ends of adjusting blocks (2-4) and connected with the locking nuts (2-6) which are adjusted by adjusting bolts (2-7); the remote-control spherical electric manned car can roll forwards at adjustable speed in any direction, and turn at any radius; and operations such as detecting and monitoring in a long-distance pipeline, indoor and outdoor movement at night, and the like can be realized by remote control under the condition that the spherical electric car is in an unmanned state.
