Meet Bruce

This weekend, Andrea and I teamed up to create a little robot named Bruce.  We were able to get him to move forward (albeit in a somewhat circular pattern) by altering the starting and ending servo motor angles. We also had to compensate for the second servo motor being in a reverse position from the first. We modified the code by adding the second servo, such that for when one’s angle was 70 for example, the second would be 180-70.

Servo myservo;

Servo myservo1;// create servo object to control a servo 

                // twelve servo objects can be created on most boards


int pos = 0;    // variable to store the servo position 

int potPin = A0;


void setup() 


  myservo.attach(9);  // attaches the servo on pin 9 to the servo object 




void loop() 


  for(pos = 70; pos <= 180; pos += 1) // goes from 70 degrees to 180 degrees 

  {                                  // in steps of 1 degree 


    myservo1.write(230 - pos);

    Serial.print(-pos);    // tell servo to go to position in variable 'pos' 

    delay(7);    // waits 15ms for the servo to reach the position 


  for(pos = 180; pos>=70; pos-=1)     // goes from 180 degrees to 70 degrees 



    myservo1.write(230 - pos);    // tell servo to go to position in variable 'pos' 

    delay(7);                       // waits 15ms for the servo to reach the position 



Midterm Sketches – The Patch (Molly + Sasha)

We are proposing a patch that you wear on your skin. The patch can generate warmth, light (possibly in shapes), and pressure. The receiver can then send these sensations back to the original sender. See sketches below for examples.


Small patch, worn on the arm (similar to a temporary tattoo). Allows for sharing gestures, like a stroke of the arm, or sharing a drawing that you feel and that appears on your patch.


Pre-determined shapes (ex: happy face) could be shared when experiencing certain emotions. Can also share a feeling or warmth of a ‘hug’ via a pressurized warmth.
