After text activity

I. Reading Exercises:

Exercise 1. Read and memorize using a dictionary:

Motorized wheels, metal segments, spin wheels,pivot,actuator,hydraulic system, pump ,air compressor, electrical circuit, electrical valves,wheels,unlimited complexity, light sensor

Exercise 2. Answer the questions:

1) What do robots have in common?

2) Why does a robot need a power source?

3) What is the most common robotic sense?

Exercise 3. Match the left part with the right:

1.The vast majority of robots do have	a) a power source to drive these actuators.
2.The hand is one of the most	b) several qualities in common.
3.The slots break	c) the light beam as the wheel spins.
4.A standard design uses	d) difficult structures to replicate in robotics.

Exercise 4.Open brackets choosing the right words:

A robot (needs/requires) a power source to drive these actuators. Most robots either have( a battery/a tube) or they plug into the wall. Hydraulic robots also need ( a pump/a valve) to pressurize the hydraulic(fluid/liquid), and pneumatic robots need an air compressor or compressed air tanks.

The writing module

III. Writing exercises:

Exercise 1. Complete the sentences with the suggested words: to, and, by, through, forward, for, from.

The actuators are all wired ____ an electrical circuit. The circuit powers electrical motors _____ solenoids directly, and it activates the hydraulic system __ manipulating electrical valves. The valves determine the pressurized fluid's path ______the machine. __ move a hydraulic leg, ____ example, the robot's controller would open the valve leading ____ the fluid pump ___ a piston cylinder attached __ that leg. The pressurized fluid would extend the piston, swiveling the leg _______.
