while (!at_other_robot_start_position) {
    move_right 1
}

while (true) {
    move right 2
}

make the robots in same line with faces in opposite direction and then keep moving left until they meet.. in these case both will move towards each other because left for one will be right for other

Question is this i think:

Given there are two robots and they are on two special points on a railway track. The robots need to be programmed with a micro chip. The code in the two chips will be the same. The robots support only these three operations

1. Move Left

2. Move Right

3. Is Special Point : Returns true if any robot is at this point and these are the starting points where robots stand initially.

Make the robots meet?

If the sensor is not between the 2 robots, it's pretty simple. Make them move in 1 direction say left or right till they meet the sensor. When they reach the sensor stop, eventually they will meet.

Case 2:

If sensor between 2 robots:

Move Left
if(sensor)
speed=speed*2;

They will meet this way as well...

Assume there will be no problem in term of line following, and assume we have a distance sensor that can measure how close the bots to the sensor, when it equals 0 , the bot meet
