The present invention is intended to provide an EMG signal controller or a wheelchair using an EMG signal controller to allow full vehicular direct drive control, and wheelchair accessory control, by using one or more EMG sensors applied to certain muscles of a subject, and translating the movement of the muscles of the subject that the EMG sensors are connected, to electrical signals causing for the operation of a motorized wheelchair. The controller and wheelchair are designed specifically for paralyzed individuals with limited motion, but may be used by any subject with or without any physical or nervous system disabilities. The present invention further provides an emergency stop which is activated in the event that the subject using the wheelchair experiences a seizure or other neurological shock.

An electric drive device includes an electric motor and a speed reducer. The electric motor includes a rotor, a stator, an electrical power converter and a motor housing. The electrical power converter is electrically connected to stator windings of the stator and is configured to supply an electric current to the stator windings. The motor housing receives the rotor, the stator and the electrical power converter. The speed reducer includes: a motor-side rotatable body that is coupled to a shaft of the rotor; and a drive-side rotatable body. The speed reducer is configured to reduce a rotational speed of the drive-side rotatable body relative to a rotational speed of the motor-side rotatable body. The motor housing and the speed reducer are integrally formed together.

Some embodiments are directed to a method for correcting a movement trajectory in a movement assistance device of a person equipped with at least one sensor device and a control unit, the method including the steps of measuring a distance between said at least one sensor and an obstacle, a separation of a coordinate system representing pairs of values of translational speeds and rotational speeds into two half-planes, by at least one separating limit of the coordinate system, into a travel exclusion zone and a permissible travel space, a definition of a second rotational speed and a second translational speed by the projection of a command point into the delimited permissible space.
