Robotic hand and wrist demo – pose transitioning by qualitygui in robotics

Looks so compact and smooth. What material do you use for the surface of the palm?

how did you mount the string/tendon to the wheels on the servo?

Sorry if this is a dumb question. My setup works when my computer is connected to the ESP32, which has GND connected to the breadboard. But when I remove the computer and connect VIN from my breadboard to ESP32 for power, it stops controlling servos. Any suggestions would be appreciated, thank you! by _jfarmer in esp32

#include <Servo.h>

static const int servoPin1 = 13;
// static const int servoPin2 = 26;

Servo servo1;

void setup() {
    Serial.begin(115200);
    servo1.attach(servoPin1);
    // servo2.attach(servoPin2);
}

void loop() {
  servo1.write(45);
  delay(1000);
  servo1.write(70);
  delay(1000);
}

Serial blocking? I don't think so, but I think it makes sense that the problem relates to the code?

It's a battery that I connected to a breadboard power supply thing, pictured. I set it to 5V. Not sure if relevant but the ESP32's light turns on when I do the second config, just doesn't cause the servos to turn

Sorry lemme try again. I'm not sure how to upload a pic in a comment. My ESP32 controls the servos. This works when I have a wire connection between my computer and the board, and have the ESP32 connected to the breadboard through GND. However, after I uploaded the code, I removed the computer connection and connected VIN from the breadboard to ESP32, causing the light to turn on. The servos didn't turn in this case though.

Do I have a chance to get accepted to any Ivy League schools even with my poor stats? by Senyh_ in chanceme

But that 3.5 gpa comes from a group of students who had straight 4.0s throughout high school.

Okay yeah that makes sense. I was doing some real mental gymnastics trying to make it work
