iglidur bearings from igus have been fitted on all rotating shafts of the ‘Porton Man’ — a robotic mannequin developed by Crawley Creatures subsidiary i-bodi Technology to help the Ministry of Defence test chemical and biological (CB) protective suits and equipment for its armed forces — to enable fluid and friction-free movement.

The ‘Porton Man’ simulates the full leg, arm and head movements of a human, as well as breathing. This allows tests of how protective clothing stands up to such action without exposing the wearer to dangerous substances.

The robotic mannequin is fitted with iglidur bearings on all rotating shafts, enabling its movements to be more fluid and friction free, with no maintenance or lubrication required. The bearings used on the robot are iglidur Z and iglidur X. Both feature excellent wear resistance, even with high loads, and are suitable for high-temperature and environmental resistance.

igus recommended these bearings because they are maintenance and corrosion free, self-lubricating, weigh seven times less than metallic rolled bearings and offer excellent chemical resistance.

The company also supplied i-bodi Technology with a ‘reverse bending radius’ (RBR) energy chain solution for the mannequin’s mounting platform. The solution was used to guide and protect cables for the rotary motion of the mannequin; this allowed the system to be rotated with no danger to the sensitive connections needed for the tests.

igus designed, supplied and installed a full custom system as well as the chainflex cables supplying the power and data.

Key benefits of product application

  • Jez Gibson-Harris, chief executive officer from i-bodi Technology, said igus provided a great service during the engineering process of the robot mannequin.
  • He described the products as being of great quality and said they are reliable, which is very important as ‘Porton Man’ is required to function without fail in a tough environment.
  • Gibson-Harris concluded: ‘The range of products supplied by igus was crucial to the project, as without igus the robot would not be able to move as freely and reliably as it does currently.’

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
