Emit something

usernamesarita 26 Jun 2017 16:10

Hello everyone!

I'm sarita and I'm trying to use the emit function, in order to have the robots communicating with each other. However, i'm with some problems.. :'(
The robots are not receiving the information emited. I tried to use the example that was provided in the website, but it still doesn't work.

This is the example:

Code for Robot 1

1. variables

var counter = 0

onevent ir_sensors

if counter == 10 then
emit move [1,0]
end

if counter == 100 then
emit move [0,1]
end

counter += 1

Code for Robot2:

1. events

onevent move
if args[0] == 1 then
leftSpeed = 400
rightSpeed = 400
else
leftSpeed = 0
rightSpeed = 0
end

onevent stop
leftSpeed = 0
rightSpeed = 0

Code for Robot3:

1. events

onevent move
if args[1] == 1 then
leftSpeed = 400
rightSpeed = 400
else
leftSpeed = 0
rightSpeed = 0
end

onevent stop
leftSpeed = 0
rightSpeed = 0

Help me please!

Hello Sarita,

Welcome to the Thymio community!
Did you call the function prox.comm.enable(1) at the beginning of your code? This function enables the local communication, without it the robots will not emit anything nor check whether they received something (this means it has to be called on every robot in the communication).

Apart from that, the robots have to be able to see each other in order to communicate, it will not work from any angle or through obstacles.
