For these reasons, mobility systems on mobile robots can be both sim- pler and more complex than those found in automobiles. For example, the Ackerman steering system in automobiles is not actually suited for high mobility. It feels right to a human, and it is well suited to higher speed travel, but a robot doesn’t care about feeling right, not yet, at least! The best mobility system for a robot to have is one that effectively accomplishes the required task, without regard to how well a human could use it | Prọqrâ 07 aboof Mắhínớs dnd Motion in -rhâ PhtỊ ìcsì MÔS ounters Mechanical Engineering Tools of Discovery Table of Contents For The Teacher An Engineering View of Civilization and Science for all classes . 1 Using Tools of Discovery in Your Classroom for all teachers . 2 Synopsis of the Career Encounters Videotape all classes . 3 A Matrix of Teaching Concepts for all teachers . 4 Guide to Thinking Like An Engineer for all classes . 5 Guide to Water And Wheels Activity for Earth Science classes . 7 Guide to Biomechanics Activity for Biology classes . 9 Guide to Compression Activity for Chemistry Physical Science classes .11 Guide to Leverage Activity for Physics Physical Science classes .13 Guide to Helping Students Identify Working Styles for all classes .15 Student Activity Photocopy Masters Thinking Like An Engineer. . . .I. 6 Water And Wheels Student Activity. 8 Biomechanics Student Activity. 10 Compression student Activity. 12 Leverage Student Activity. 14 Working Styles Student Student Career Background Photocopy Masters What Mechanical Engineers Do. 17 How Mechanical Engineers Work. 18 Mechanical Engineering Mechanical Engineering Mechanical Engineering Engineering Career An Engineering View Of Civilization And Science e are the inventors and the toolmakers. No other w Ễ species creates and uses w Ễ tools the way we do. A Bf chimpanzee can use a twig w w to pry open an anthill there is a species of seabird that -------------------- cracks oysters open on a rock and troops of baboons have even been known to use sticks and stones as weapons. But no chimp bird or baboon - or any other animal - has yet conceived of a tool that combines both stick and stone. That is invention and that is the sole province of humankind. Probably we invent tools because we are so poorly equipped to survive otherwise. Without feathers or fur or claw or fang we are hopelessly disadvantaged in the fight for survival.
