I had some time to mess around with the New blockly, It is still showing up as a white screen from time to time. But when I did manage to keep it open I made this small program for the Otto remix I call October.

Now before the new blockly, after the robot did a small walk with the loop, instead of staying in the position of the last leg up or down when the walk timed out, I could use a "Home" block to make it reset to a neutral position. Can you take a look at the code and see if I need to add something to it. It can be as simple as not knowing how to setup the blocks, because they are new.
Thanks.

#include <Otto9.h>
Otto9 Otto;
#include <Servo.h>

#define PIN_YL 2 // left leg, servo[0]
#define PIN_YR 3 // right leg, servo[1]
#define PIN_RL 4 // left foot, servo[2]
#define PIN_RR 5 // right foot, servo[3]
#define PIN_Trigger 8 // ultrasonic sensor trigger
#define PIN_Echo 9 // ultrasonic sensor echo
#define PIN_Buzzer 13 //buzzer

Servo servo_6;
Servo servo_7;

void Setup_Configuration() {
servo_6.write(95); delay(0);
servo_7.write(100); delay(0);
Otto.home();
}

void Hands_Down() {
servo_6.write(10); delay(0);
servo_7.write(180); delay(0);
}

void Hands_Up() {
// L
servo_6.write(180); delay(0);
// R
servo_7.write(28); delay(0);
}


void setup() {
Otto.init(PIN_YL, PIN_YR, PIN_RL, PIN_RR, true, A6, PIN_Buzzer, PIN_Trigger, PIN_Echo);
Setup_Configuration();

Otto.setTrims(10,0,0,0);
servo_6.attach(6);
servo_7.attach(7);
}

void loop() {
Hands_Down();
delay(4*1000);
Hands_Up();
delay(4*1000);
Hands_Down();
delay(1*1000);
for (int count=0 ; count<2 ; count++) {
Otto.walk(1,1000,1); // FORWARD
}
delay(1*1000);
