1
00:00:11,060 --> 00:00:15,060
Zeina, made by Nadia and Ainhoa.

2
00:00:16,059 --> 00:00:20,420
This is Zeina.

3
00:00:21,420 --> 00:00:35,289
What does it do? Our robot is designed to clean the rivers of trash and to explore rivers, seas, oceans and lakes.

4
00:00:40,219 --> 00:00:41,219
How does it work?

5
00:00:42,219 --> 00:00:47,219
First, Zeina recollects the trash and stores it on a specific place for trash.

6
00:00:47,219 --> 00:00:52,219
Second, from the holes of the back, Sena produced clean water for the river.

7
00:00:52,219 --> 00:00:57,219
And third, the algae of Sena's curve maintained the water purified.

8
00:01:01,390 --> 00:01:07,390
Who will use it? We think that all people that want to help clean rivers could use it,

9
00:01:07,390 --> 00:01:11,390
but mainly public institutions and the culture governments.

10
00:01:12,390 --> 00:01:19,140
How will our invention change people's lives?

11
00:01:19,140 --> 00:01:25,140
We will have more fresh air, less pollution and our rivers will be more clean than now.

12
00:01:29,819 --> 00:01:32,819
What problems might our invention solve?

13
00:01:32,819 --> 00:01:35,819
Our robot will solve the largest problems.

14
00:01:35,819 --> 00:01:41,819
But to put here an example, SENA will improve animals living environments.

15
00:01:43,819 --> 00:01:48,659
Could SENA be invented in the future?

16
00:01:48,659 --> 00:01:53,659
We think that SENA could be invented, but not exactly like it is in here.

17
00:01:53,659 --> 00:01:59,560
We think that scientists could make a similar robot, but in other case Aino and me could

18
00:01:59,560 --> 00:02:02,560
invent this robot in the future.

19
00:02:02,560 --> 00:02:08,919
Thanks for listening!
