Recently (September 15, 2014) the news website of MIT reported that the Cheetah Robot has been updated, and is now able to run outside, untethered.

The information is interesting for my students because of the technical details of the innovation, and is interesting for me because of the language material of the text, and the way it can be compared to the earlier text.
As for the first text, there is an accompanying video (2:35) that shows the robot running and jumping, while two members of the team explain how it works. Neither is a native speaker of English, but this is good practice for students to understand a variety of accents.
As in my first post about the Cheetah Robot, the following features can be noted:
Areas of text that explain or give examples:
- In general, the faster the desired speed, the more force must be applied to propel the robot forward.
- ... by adapting a force-based approach, the cheetah-bot is able to handle rougher terrain, such as ...
- The percentage of time a leg spends on the ground rather than in the air is referred to in biomechanics as a "duty cycle"; the faster an animal runs, the shorter its duty cycle.
Verbs of what researchers "do":
- take (robot) for a test run
- present (details of robot)
- They actually increase their stride length by pushing downward harder and increasing their ground force, so they can fly more while keeping the same frequency.
- In experiments, the team ran the robot at progressively smaller duty cycles, ...
- ... the robot was able to run at higher speeds without falling.
- fastest / faster

- more stable, agile and dynamic
- the faster an animal runs, the shorter its duty cycle
- ramp up to
- pump its legs
- propel forward
- cycle their legs
