Outline
The present invention relates to an additive for carbon nanotube and plastic composites comprising a functionalized maleic acid anhydride-olefin copolymer, wherein the maleic acid anhydride monomer units are partially or completely converted to dicarboxylic acid ester amide and / or dicarboxylic acid half ester and / or dicarboxylic acid imide monomer units, wherein the number of maleic acid anhydride monomer units of formula (I) is from 1 to 1 to 8. The invented composite can be used, for example, for the production of heavy-duty plastics, aircraft and vehicle body components, structural materials replacing high-strength metal parts, building cladding and components, insulation materials, electrical and thermal coatings, sealants, furniture components, high-strength nets and ropes.

The aim of the invention is to provide the stepper mechanism of human-shaped, so-called humanoid robots with a simpler structure, but at the same time with a cheaper, more stable stepping structure which is more suitable for overcoming obstacles. In the stepping device subject matter of the invention, parallel robots are used which have three robot arms. The stepping device for a humanoid robot, being the subject matter of the invention, comprises at least two robot legs (101, 102), each robot leg (101, 102) comprising three robot arms (Lll-13) connected in parallel, wherein the robot arms (Lll-13) at their upper ends are connected to a rigid base plate (110) and at the lower ends to a rigid mobile base plate. The upper ends of the robot arms (L11-13; L21-23) of each robot leg (101, 102) are located at the vertices of a base triangle (111, 112) of any shape, where the vertices of each base triangle (111, 112) point to mobile connectors located on the rigid stabile base plate. The lower ends of the robot arms (L11-13; L21-23) of each robot leg (101, 102) are located at the vertices of a moving triangle (121, 122) of any shape, where the vertices of each moving triangle (121, 122) point to mobile connectors located on a mobile rigid base plate. The robot arms (Lll-13; L21-23) associated with a robot leg (101, 102) together provide at least three degrees of freedom of movement for that robot leg (101, 102). Each robot arm (L11-13; L21-23) is provided with at least one uniaxial drive, preferably a servomotor and associated drive mechanisms. The base plates (110) of the robot legs (101, 102) are connected to each other.
