A MICRO ROVER RoSA-2

The micro rover IDD-1,2 (Fig.1) was a prototype for development of the micro robot RoSa-2 (“Micro robot for scientific applications 2”) within the framework of the ESA’s Technological Research and Development program (1999-2001) (Fig.4,5) [9]. ESA’s project leader - G. Visentin.

Objective of the Work: Development of a mobile drilling and sampling system that comprises a rover, a drill, sample storage, and docking and sample delivery port mounted on a Lander module.

The locomotion system developed and built by RCL (Designers: V.Kucherenko, A.Bogatchev, S.Vladykin, Project Manager - S.Matrossov) under contract with ESA is intended to transport a payload as well as to move the drilling unit (the part of the payload), which was developed by Helsinki University of Technology HUT (prof. A.Halme, J.Suomela, J.Saaren) in co-operation with Space systems Finland (M. Antilla) and VTT Automation (T.Ylikorpi).

Micro robot RoSa-2

The locomotion system has the following main characteristics:

maximum motion speed on the horizontal surface, m/h 60
mass of chassis/ payload mass, kg 5/7
overall dimensions (LxWxH) in stowed position, mm 400x400x110
slope climbed (with minimum clearance), degr. up to 30
obstacle surmounted (with minimum clearance), mm 60 (height)
cable length, m 40
