Background Information

In an uncertain future, humankind wants to control the surface of the planet Omicron Persei 8, located out of the alpha centauri star system. For this purpose, transceivers and certain type of robots are designed. Transceivers located to fixed locations, and robots are mobile and should be stay connected to the transceiver towers, otherwise, if robots cannot build a duplex connection (both transmitting and receiving signals) more than 60 seconds, it is assumed that the robot unit can be (or worse it is) captured by the aliens, and the units destroy themselves due to prevent any possible information leakage. Your task is to create a simulator to test the possible algorithms for this mission. In the planet Omicron Persei 8, the power of the electromagnetic waves used for communication decay linearly and inversely proportional to the distance from transceivers or robot units. A battlefield is composed of transceivers and the mobile units (robots)

. Transceiver: Transceivers (transmitter and receiver) (can also be think as base stations) are stationary and have fixed location. Every transceiver has a different transmitting power and minimum receiving power according to used components in them. Once a transceiver set up in the battlefield, then a local/internal time counter starts to run and count every second. Every transceiver should have a unique ID to build up separate communication channels.

Robots: While transceivers are stationary (fixed), robots can move depending on the class of the unit. Robots has their unique IDs, different than transceivers. Their transmitting power and minimum receiving powers are all same: transmitting power is 1 W and minimum receiving power is 10 mW. Since they move, they should have a velocity in meters/seconds (m/s). They also have status flag that shows dead or alive, and a counter that counts the disconnected time, if the connection is lost. According to trajectories, there are three types:Robot units share the properties of the Transceivers. They move with a constant speed in a constant direction, in other words they have a constant velocity. The velocity information is given when the robot unit is set up in the battlefield.

Guard : Guard units share the properties of the Robots. Moreover, guards move in a square trajectory and turn right with a given period. The default value for the period is set to 60 seconds

. Psycho : Psycho units share the properties of the Robots. However, their move and velocity are random, in addition, the changing frequency of the velocity is also random. The velocity a psycho can be 10 m/s {vx,vy} -10 m/s.

Battlefield: The battlefield should manage all the units, both transceivers and robots. Keep track of their status, position and other vital information related with the mission.

i want to write battle field class

Battle_Field class:

This class will hold information about the battlefield, including the list of transceivers, robots, and dead robots. It advances the time and update the information of all units properly, track the global time in seconds, and if a mobile unit does not communicate more than 60 seconds, it updates the status info of the unit from alive to dead and move the unit to dead robots list. The rest of the methods are given below.

Methods	Explanation
__init__()	__init__ method should not take any parameters, it should create an instance of the Battle_Field class. Important data for this class is global time, the list of transceivers, robots, and dead robots. Global time should start from 0. > >> field=Battle_Field()
add_transceiver(x,y,tpower,rpower)	This method should take x and y coordinates of the transceiver unit and transmitting and minimum receiving powers, then creates an instance of the Transceiver class and add it to the transceiver list. The default value for minimum receiving power is 1 mW. >>> field.add_transceiver(0,0,10) >>> field.add_transceiver(1200,0,1 5) >>> field.add_transceiver(500,500,12)
add_robot(x, y, vx,vy)	This method should take x, y coordinates of the robot unit in meters and the x and y components of the velocity of the robot unit in meter/seconds, then creates an instance of the Robot class and add it to the robot list. >>> field.add_robot(10,25,10,0) >>> field.add_robot(500,750,-10,10) >>> field.add_robot(500,750,5,10)
add_guard(x,y,vx,vy,timer,period)	This method should take x, y coordinates of the guard unit in meters and the x and y components of the velocity of the robot unit in meter/seconds, period in seconds, and localtime, then creates an instance of the Guard class and add it to the robot list. Default value of the period is 60 s. Default value of the localtime is 0 s. >>> field.add_guard(40,58,10,10) >>> field.add_guard(1000,0,10,0) >>> field.add_guard(750,800,-10,0)
add_psycho(x, y)	This method should take x, y coordinates of the psycho unit in meters, then creates an instance of the Guard class and add it to the robot list. >>> field.add_psycho(-10,60) >>> field.add_psycho(20,320) >>> field.add_psycho(500,1020) >>> field.add_psycho(750,300) >>> field.add_psycho(-300,320) >>> field.add_psycho(0,0)
