Here is my code

static int lm_speed = 0;

int rightm = 3; //PWM output
int leftm = 5; //PWM oupput
int servpin = 9;
Servo servo1;
NewPing sonarR(TRIGGER_PINR, ECHO_PINR, MAX_DISTANCE);


void setup()

What does that mean to us regular people?

You reversed the symbols in greater-than-or-equal-to, => should be >=.

int servpin = 9;
Servo servo1;
NewPing sonarR(TRIGGER_PINR, ECHO_PINR, MAX_DISTANCE);

"us" is just short for ultrasonic sensor.

"us" is just short for ultrasonic sensor.

It could also mean a reference to a group to which one belongs.

That usually happens when the code has been copied from a Web page that uses Unicode characters somewhere in the code.

Copy the code back into the IDE from the code box in your original post above and you should be OK, but don't forget to fix the => errors
