Multifunctional End Effector for Regolith Construction, Acquisition, and Transfer (MEERCAT)

Presentation prepared for ASCE Earth and Space. Presentation covers the capabilities of the MEERCAT system with videos demonstrating con ops. The MEERCAT system specs are taken from a previously STRIVES approved flyer on MEERCAT. Presentation will not be part of ASCE Earth and Space but should still be submitted through STRIVES for use with public facing business developments.

The completion of the construction and commissioning of the liquid radwaste treatment plant at ChNPP - 15685

Since a beginning of ChNPP operation, and after a tragedy in 1986, a few thousands m{sup 3} of LRW have been collected in a storage tanks. In 2004 ChNPP started the new project on creation of LRW treatment plant (LRWTP) financed from EBRD fund. But it was stopped in 2008 because of financial and contract problems. In 2010, FSUE RADON jointly with Ukrainian partners has won a tender on completion of LRWTP, in particular I and C system. The purpose of LRTP is to process liquid rad-wastes from SSE 'Chernobyl NPP' site and those liquids stored in the LRWS and SLRWS tanks as well as the would-be wastes after ChNPP Power Units 1, 2 and 3 decommissioning. The LRTP design lifetime - 20 years. (authors)

Additive Manufacturing Advances to Facilitate Novel Robot and Remote System Construction - 18493

Additive manufacturing (AM), in both polymer and metal, has advanced to the point where it can significantly facilitate robot and remote system design and implementation. Properly used AM creates features and capabilities otherwise not possible in machined or cast products. AM design rules are still being developed and must be applied differently based on the process and purpose of the final component, but progress is being made in practical implementation. Polymer-based AM has been commercially available for quite some time and is regularly used for prototyping and test fitting parts before they are fabricated from metal or produced in low production quantity parts that do not require high structural strength. Metal printing processes are more diverse than polymer print processes. Both polymer and metal printing systems can be used to make parts or complete systems for robotics. Two implementation examples that illustrate the possibilities and identify issues that remain in metal printing are: a dual arm hydraulic manipulator and a distal link of an excavator arm. The dual arm hydraulic manipulator was printed in titanium using an e-beam fusing process. All hydraulics and electrical cabling passageways were printed into the manipulator; there are no external hoses or cables. The distal link of an excavator arm was printed using a wire-fed metal inert gas process. The excavator was then used for digging as part of an equipment exposition validating the structural integrity of the printed part. (authors)
