The invention herein discloses a system including building blocks intended for educational, amusement or functional use of assembling into mechanical and electro-mechanical constructions. The building blocks are electrically conductive and have an electrical connector with an asymmetry property around one of the main, or natural, assembly planes. The asymmetric properties allow the connector to maintain high electrical conductance when assembled near an adjacent building block, without harming the building blocks physically and without requiring complex assembly rules and restrictions. The system can present rotational symmetry of 180 degrees, and can present elastic properties or magnetic properties to further increase the conductivity and durability of the connectors.

An apparatus that includes a housing containing a motor that is electrically connected to a power source. An enclosed motorized assembly is connected to the housing and contains secure points located in an outer surface thereof and LEDs therein. An object is affixed to the motorized assembly and contains insertion points. A slip ring is secured around a motor shaft of the motor and electrically connects to a first conductive plate that is secured within the housing. The first conductive plate is further electrically connected to the LEDs. A second conductive plate is electrically connected to the motor shaft and the LEDs. A plurality of extension elements include a first and second end, wherein the first end is secured to the secure points and the plurality of extension elements radiate or transmit light from the LEDs.

A bracket for modular luminaire includes a polyhedral module and a connector connected to the polyhedral module. The polyhedral module is a polyhedron provided with a cavity therein, and each surface of the polyhedron is provided with a stepped through-hole connected to the cavity, thereby forming a first annular protrusion at a junction of the stepped through-hole and the cavity. The connector includes a connector body having a cylindrical shape. On an outer periphery of the connector body, a second annular protrusion, a third annular protrusion, a fourth annular protrusion, and a fifth annular protrusion protrude outwards in a radial direction and are spaced apart from each other, and formed successively from a left end portion to a right end portion of the connector body. A left end of the connector is inserted into the stepped through-hole of the polyhedral module.

According to some embodiments, a first toy body comprises a first level oriented in a first direction, and a second level oriented in a second direction. A second toy body comprises a third level oriented in the first direction, and a fourth level oriented in the second direction, wherein the first direction is perpendicular to the second direction.

An interactive toy includes a housing, a control module, a motor, a rotating shaft, and an external member. The rotating shaft is exposed outside the housing, and is connected to the external member. The control module is configured to control the motor to drive the rotating shaft to rotate. The toy further includes a measurement module and an analysis module. The measurement module is configured to measure an angle by which the rotating shaft rotates from an initial stationary state to the state in which its rotating speed reaches the maximum. The analysis module is configured to compare a preset reference angle with the angle by which the rotating shaft from the initial stationary state to the state in which the rotating speed of the rotating shaft reaches the maximum to determine whether the external member encounters an obstacle.
