Abstract: A toy construction robotics system including a robotics control unit, the robotics control unit comprising: a housing comprising coupling elements configured for releasably interconnecting the robotics control unit with cooperating toy construction elements; a processor comprising programmed instructions; a plurality of I/O-ports connected to communicate with the processor; a plurality of separate light emitters arranged in a two-dimensional array on a front side of the housing, each of the light emitters being operable in response to instructions from the processor so as to produce at least two different indicator states; wherein the light emitters are aligned with respect to the I/O-ports such that each of the I/O-ports has an associated light emitter next to it. The light emitters may be operable, in response to instructions from the processor, to produce a machine readable code encoding data in respect of the robotics control unit. The machine readable code may comprise instructions for interaction between the robotics control unit and an external device.

Abstract: A connector element for a construction system, the construction system having first and second construction elements. The first type of construction elements comprising at least one construction element having connector knobs formed on a surface thereof and arranged in a regular two-dimensional lattice. The second type of construction elements comprising at least one construction element configured to cooperate with a connector peg to form a snap connection. The connector element comprising an elongate body having first and second ends and a longitudinal axis (A1). The first end having a first cylindrical connector portion, having an inner surface configured to form a friction fit, and an outer surface configured to form a friction fit between four neighbouring connector knobs formed on a first type of construction element. A second cylindrical connector portion configured to form a snap connection with the cylindrical connector opening of the second type of construction elements.
