80 Make: Robotic Arms

WHAT ARE WE BUILDING?

One of the most interesting things about inverse kinematics is the ability

to program a robotic arm to move in nice, straight lines, and in this project,

we’ll begin to take a look at how that’s possible. The key will be to coordinate

the movement of both actuators at the same time.

#include <Servo.h>

Servo servo1;

Servo servo2;

void setup() {

servo1.attach(3);

servo2.attach(5);

}

void loop() {

servo1.write(90);

servo2.write(90);

delay(1000);

for (int pos = 0; pos <= 30; pos++) {

servo1.write(90 + pos);

servo2.write(90 - pos);

delay(100);

}

for (int pos = 30; pos >= 0; pos--) {

servo1.write(90 + pos);
