An affordable, highly articulated, child-size humanoid robot could potentially be used for various purposes, widening the design space of humanoids for further study. Several findings indicated that normal children and children with autism interact well with humanoids. This paper presents a child-sized humanoid robot (HBS-1) intended primarily for children’s education and rehabilitation. The de...

Extending the mechanical lifetime of NBR (i.e., poly(acrylonitrile-co-butadiene)), a large-volume synthetic rubber, requires better understanding its structure–property relationships. We demonstrate that industrial-grade and uncross-linked can be mechanically rejuvenated physically aged due to an inhomogeneous distribution monomers along polymer chains. As opposed nonpolar SBR counterpart poly(...

Fused Deposition Modeling (FDM) is a kind of Rapid prototyping (RP) technique, which allows direct transformation of CAD files into physical models. This paper attempts to identify and study the influence of electroplating layer thickness on the mechanical strength of Acrylonitrile butadiene styrene (ABS) samples developed from the FDM process. The study is conducted on the tensile test samples...

Abstract Polymers are widely employed in many areas, e.g. transport, packaging, electronic devices, etcetera. Among them, acrylonitrile–butadiene–styrene (ABS) is one of the most polymers due to its mechanical properties, ease mechanize and recyclability. Nevertheless, according fire ABS behaviour usually worse than other polymers, therefore, they have be upgraded with flame retardant additives...

The accelerated thermal ageing of ABS films has been investigated over a wide range exposure temperatures in air, by FTIR, GPC, AFM and tensile testing order to determine the origin ductile/brittle transition during exposure. Besides formation oxidation products decrease unsaturated bonds butadiene phase, molar mass changes have highlighted chain scission process. If is associated SAN crosslink...

Paper presents knowledge about types of test in area of materials properties of selected methods of rapid prototyping technologies. In today used rapid prototyping technologies for production of models and final parts are used materials in initial state as solid, liquid or powder material structure. In solid state are used various forms such as pellets, wire or laminates. Basic range materials ...

It is well known that in blend modification, PC(Polycarbonate)/ABS(Acrylonitrile-Butadiene -Styrene) alloy polymers were used very common , but because of its high production cost and poor processing performance limited its application in marine materials. To improve the problem, We studied the behavior of ABS/PC alloy performance, and made a lot of exploration to increase the toughness, made i...

It is proposed that by using computing analysis software and 3D fabrication techniques, low cost plastic trumpet bells could be produced for different music genres by altering their timbres. These may be attached to the trumpet in a similar manner to that of a tuning bell trumpet. The novel bells are designed to eliminate or enhance particular harmonics to change their brightness by altering th...
