or a structure that functions wholly or partially as a joint or the structure of base 311 may include a separate joint attached to its structure thereby affording axle 301 with at least one degree of freedom of motion thus lamp 300 can have at least 2 degrees of freedom of motion as long as the motion that is afforded to axles 301 and 302 respectively is not along the same abstract axis the specification of number of axles and associated joints to the lamp structure functions to provide it with enough degrees of freedom of motion to accomplish a task thus a task requiring u201c n u201d degrees of freedom of motion will use an embodiment with will have a u201c n j u201d number of joints in which u201c j u201d is the number of degrees of freedom of motion per joint assuming that joints have a uniform number of degrees of freedom of motion the lamp is configured to hold a smartphone on its structure for instance the smartphone can be held at terminal section 313 smartphone sensors which include a microphone and can include one or more video cameras a location module e g global positioning system gps galileo global navigation satellite system glonass inclinometer and gyroscope and lamp sensors which can include proximity sensors that can be used in prevention of collisions with objects in the vicinity of the system the actuators for the system of the lamp and the smartphone comprise smartphone actuators which include the smartphone speaker s and display screen and can also include vibrating modules and lamp actuators which include light sources and can include sound actuators further.
