Practice with these pages to find
the following words:
Where have all the animals gone? There are many reasons that animals disappear from the face of the earth. Once an animal disappears it is gone forever - EXTINCT.
Some animals are currently in danger of disappearing. They are not gone yet, but only a few remain - ENDANGERED.
Copy the words for each
line as you find them on the pages and paste them onto a word processed
page.
We have built a series of legged robots
for experiments on active balance in dynamic legged locomotion.
Taken collectively, these robots have
traversed simple paths, run with several different gaits (hop, run, trot,
pace, bound), run fast (13 mph), jumped over obstacles, controlled step
length, climbed a simplified stairway, walked over ramps, and performed
rudimentary gymnastic movements. Where have all the animals gone?
Although no one robot performed all these tasks, the machines all use a
common set of balance and control principles.
