An electrical mechanical toy has a housing including a base. A small electrical drive motor is mounted on the base and a drive diverter-transmission operatively connects to the drive motor. Also attached to the base is an endless belt mounting member having at least one endless belt mounted thereon such that the endless belt is capable of continuously traveling or orbiting about the mounting member. The drive diverter-transmission is connected to the endless belt such that the endless belt is driven by the drive motor about the mounting member. The endless belt includes at least one obstacle on its surface. An object member is slidably mounted on the base and includes an object attached to the object member and positioned proximal to the surface of the endless belt allowing the object to slide transversely to the direction of travel of the endless belt between an interference position with the obstacle on the surface of the endless belt and a non-interference position wherein the object does not interfere with the obstacle. The toy includes a detector which detects when the object is in the interference position with the obstacle and which disconnects the drive diverter-transmission from driving the endless belt when the obstacle is in the interference position. If the drive diverter-transmission is so disconnected a manual reset is actuated to restart movement of the endless belt.
