Planar jumping with stable landing through foot orientation design and ankle joint control

Qilong YUAN, I-Ming CHEN

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 2,   Pages 100-108 doi: 10.1007/s11465-012-0318-3

Abstract:

This paper introduces a method to generate the planar jumping motion for biped robot. In this work, through determining the upper body posture trajectory in the flight phase, the foot landing posture is made to be flat while landing. Together with properly designing the trajectory for local center of gravity and the foot landing velocity, the soft landing trajectory is generated. A controller on the ankle joint is added to avoid significant impact with the ground and stabilize the robot after landing. Jumping motion with stable landing is achieved in a dynamic simulation environment based on this method.

Management and Practice of Large-Scale Modern Coal Enterprises

An Wang

Frontiers of Engineering Management 2014, Volume 1, Issue 1,   Pages 13-17 doi: 10.15302/J-FEM-2014004

Abstract: As the coal-dominated energy structure will remain unchanged in the short term, the sustainable development of the coal industry is still serving as one of the foundations for the sound development of the national economy. The construction of modernized mines based on "four orientations", that is, orientations of scale production, modern technology and equipment, informationized management and professional working team, has been rapidly enhancing its development in the recent decade. However, in the next decade or an even longer period, the industry, with the energy centre shifting to the West of China, will be exposed to new options and development in the layout, structure, model, technology, etc.

Strategic Study of CAE 2012, Volume 14, Issue 4,   Pages 26-30

Abstract:

This paper introduces a new type of perforating completion technology modularization wire line perforating technology.It uses monocable to run the hanging device of the perforator to the desired depth;then the full modular perforating guns required by the perforating operations are run to the well one after another;at last,the perforating charges are detonated.With the technology,the aim of running multiple guns individually and detonating at one time is realized.Based on this technology,with a special guiding design,the wire line oriented perforating is completed.The technology is making full use of the special features of the wire line conveyed method,including less equipment,easy operation,and short job time,etc., also fulfills some functions of tubing conveyed perforating,such as underbalanced perforating in the whole well,preventing blow out,etc.In addition,in the perforation in high pressure oil and gas wells,the modular perforators can be dropped to well bottom.Thus the wells can produce directly without restriction to the high pressure oil and gas.If the down hole tools need to be pulled out,the operation can be completed with the wellhead lubricator for the tool in the well is not long.
