According to “Agronne National Laboratory”, gloves made of materials such as Latex and Nitrile would protect hands from corrosives, oils, and solvents.
The table below shows the type of substances a certain material could be used against, as well as the pros & cons:
From the types of materials shown in the tables above, the easiest to obtain and the most beneficial would be latex and nitrile.
Latex is the stable dispersion (emulsion) of polymer microparticles in an aqueous medium. Latexes may be natural or synthetic. It can be made synthetically by polymerizing a monomer such as styrene that has been emulsified with surfactants.
Latex as found in nature is a milky fluid found in 10% of all flowering plants (angiosperms). It is a complex emulsion consisting of proteins, alkaloids, starches, sugars, oils, tannins, resins, and gums that coagulate on exposure to air.
A nitrile is any organic compound that has a −C≡N functional group. The prefix cyano- is used interchangeably with the term nitrile in industrial literature. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in the latex-free laboratory and medical gloves simply called; "nitrile gloves." Nitrile rubber is also widely used as automotive and other seals since it is resistant to fuels and oils. Organic compounds containing multiple nitrile groups are known as cyanocarbons.
Thus, based on the information found, our group decided to use nitrile to make the casing as it has a stronger resistance against acids and is easier to obtain.
A robotic claw is a type normally programmable mechanical arm, similar to the functions of a human arm ; this may be the sum total of the mechanism or may be part of a more complex robot. The parts of these manipulators or arms are interconnected through articulated joints that allow both a rotational movement ( such as an articulated robot ) , as a translational linear move.
