tinyBot Grabbing At the Air

tinyBotGrab uses the gripper for the first time! The robotGrab command sets the force tinyBot applies with the gripper. Positive numbers close the gripper, negative numbers open it. Like moving servos fast, the robotGrab command requires a dely.

Commands used:



What We Learn:

Unlike the channel 1 through 3 servos, the gripper applies a force instead of moving to a position. It's important to remember this, because it means the gripper will take a minute to get where we want it to go.

void setup() {
  // put your setup code here, to run once:


void loop() {
  // put your main code here, to run repeatedly:
  delay(5000);  //this command waits for 5000 milliseconds, which is the same as 5 seconds.
  robotGrab(100);   //The higher the number, the harder the robot grabs. 127 is the maximum
  delay(2000);  //let's wait 2000 milliseconds (2 seconds) to make sure the robot has a good grip
  robotGrab(-100);  //the negative number will open the gripper
  robotGrab(0);  //we need to turn off the gripper by resting to zero. That keeps it from wearing out.
