“…These factors influence the development of local agriculture and open a market share for automation also of small machines (mass lower than three tons). Differently from heavy tractors, small machines with competitive costs cannot be effectively developed simply by modifying existing manual driven models: their architecture should be rethought for automation [24].…”

<p class="Abstract">The mine action community suffers from a lack of information sharing among stakeholders. Since 2004, Snail Aid has been working on Disarmadillo, a dramatic shift in paradigm: an open source hardware platform for humanitarian demining. Developed mainly thanks to volunteers’ work across more than 15 years, the machine is now going to get a push thanks to the project Disarmadillo+, in collaboration between Snail Aid - Technology for Development and the Italian Institute of Technology. The new version of the machine will be improved in terms of manoeuvrability, modularity, versatility, without compromising its characteristic features. The re-design will take into account the need of keeping the cost low and the technology appropriate to the context where it will work. The ability of the machine to serve two different purposes will also be preserved: the machine will keep on being easily convertible to its original agricultural nature, being developed around a commercial off-the-shelf powertiller. The paper presents the machine and the research work foreseen within the new project</p>

“…In this paper, we present the data obtained during an experimental campaign performed as a part of the development of a remotely controlled demining machine, based on an agricultural tractor (Cepolina et al, 2014) equipped with blast resistant wheels. Since during demining operations detonation of mines might occur beneath wheels, the response of these components must be assessed.…”

This paper presents the results obtained during an experimental campaign on blast resistant wheels designed for a low-cost demining machine, derived from an agricultural tractor. Such wheels must fulfil two requirements: first, they have to be able to retain their mechanical integrity in case of blast and still work after one or more explosions, in order to be able to drive the machine out of the minefield without human intervention; second, they must reduce as much as possible the amount of energy transferred to the vehicle, to protect the on-board equipment from the effect of the detonation of a landmine. One of the goals of the experimental activity was to compare two wheels characterized by different designs. Mechanical performance and capacity of the wheels to reduce the energy transferred to the vehicle have been assessed to verify whether the wheels were suitable for the task and to identify which wheel performs best. Physical integrity of both wheels was assessed by visual inspection after each explosion. To evaluate the energy transferred to the vehicle, a measurement of the potential energy transferred, by means of a ballistic pendulum, equipped with an encoder, was performed together with a triaxial acceleration measurement in correspondence of the wheel hub. The triaxial accelerometer measurement was then also used to assess the behaviour of the wheels mounted on the vehicle after tests on the ballistic pendulum. Wheel performances have been quantified using specific features and frequency domain functions, related to the damage induced by the vibration at the interface between the hub and the demining machine. The obtained results suggest that the heaviest wheel performs better both in terms of mechanical integrity and of shock response.
