EXERCISE A.
In the paragraph below, you must find the words that belong to the same family as the words in brackets.They could be verbs, adverbs, adjectives, etc.. ( i.e. " module" gives the adjective "modular" that is required in the second sentence.) Once you've found the words type them in the space provided for each numbered gap below the text.
Bentley and his colleague Siavash Haroun Mahdavi borrowed a trick from (1) ……………….. (evolve) to allow their robot to adapt to damage. The snakebot is made up of modular vertebral units that "snap" together to form a snake-like body .
Each unit contains three separate "muscles" running down its (2) ………………..(long). The muscles are made out of wires of a shape-memory alloy called nitinol, an alloy of nickel and titanium whose crystal structure shrinks when an (3) ……………….. (electrify) current is applied to it. (4) ……………….. (use), it regains its original shape and (5) ……………….. (long) once the current is removed.
To make the snakebot move in a particular direction, a current is (6) ……………….. application) to certain wires. When the current is removed, the wires spring back and the robot will jump forward. The software for making a robot wriggle like a snake is fairly (7) ……………….. (straight) . But ensuring that the snake will keep moving even if a segment is damaged is trickier, and relies on different segments taking over from the damaged ones.
So Bentley and Mahdavi have created a (8) ……………….. (gene) algorithm (GA) - a software routine that takes a " (9) ……………….. (survive) of the fittest" approach - to produce a system that (10) ……………….. (continue) evolves to improve itself.
