求翻译：我们进行了管道机器人的变管径需求的研究，在机械机构上采用了可活动支架机构，可以有级调整机构位姿以适应不同管径的要求，可以无级调整履带轮位姿以达到最佳受力、最佳运动状况。是什么意思？

We carried out the needs of the change in diameter of the pipeline robot, the movable bracket institutions in the machinery sector, can adjust body position and posture to adapt to the requirements of different diameters can be stepless adjustment of the track wheels position and orientation in orde

We have had a pipe diameter of robots for research needs, and the mechanical activity can be used on a stand, there can be beauty-level adjustment to adapt to a different pipe diameter, can be infinitely varied track wheel position in order to achieve the best and best movement.

We carried on the pipeline robot to change the caliber demand the research, used on the mechanical organization has been possible the movable support organization, might the having steps adjusting mechanism position posture adapt the different caliber request, might the stepless adjustment track whe

We had a study of variable diameter of pipeline robot needs, support agencies on the machine body adopts the activities, you can adjust body position and orientation to meet the demands of different caliber, you can continuously adjust the track wheel pose for maximum force, best condition.
