This paper considers a polygon formation control of multiple robots with nonholonomic constraintsenclosing a goal target and double-level-control collision avoidance scheme. Doublelevel-control scheme consisted of upper-level and lower-level controls are proposed for trajectorygeneration and tracking control of multi-robot systems. Both upper-level and lower-levelcontrols operate collision avoidance mechanisms based on potential functions. The proposedcontrol scheme guarantees that the group of robots are kept in the polygon formation and drivento a goal, while avoiding collisions during the travel. Moreover, the designed interaction betweenthe upper- and lower-level controls guarantees that the mobile robots are not trapped in localminima or deadlock case. Experiments of the formation of three-robots are conducted to showthe performance of the mobile robots in accomplishing a polygon formation while achieving thegoal without any collision and no local minima.

Transformation of lignin to valuable chemicals via sustainable pathways is recognized as one of the most efficient ways to explore its value and replace the nonrenewable petroleum resource. In this work, an environmental-friendly transfer hydrogenation process has been developed to convert lignin derived2,6-dimethoxybenzoquinone to 1,4-cyclohexanediol. Compared with previous work under hydrogen pressure(30 bar), this process uses isopropanol as both solvent and hydrogen donor, which significantly simply the operation process. The core of this study is the design and preparation of Mn modified Raney Ni catalysts by ball milling process. A series of Raney Ni Mn catalysts with different ball milling time and Mn content were prepared and investigated. Characterizations by X-ray diffraction(XRD), X-ray photoelectron spectroscopy(XPS), scanning electron microscope(SEM) and transmission electron microscope(TEM) etc. showed that Ni Mn Al alloy was formed during the ball milling process and then transformed to Ni Mn alloy after treatment by aqueous Na OH. After optimization, a yield as high as 86.1% could be achieved for 1,4-cyclohexanediol at 200℃ in only 1 h.
