The Remote Assist Hand is a robotic arm with a gripping hand that is able to sense how much pressure it feels when gripping and holding objects. It uses a load cell to measure this force and sends that information to a computer through an ESP32 microcontroller. Unlike most robotic arms, Remote Assist Hand can sense physical resistance and communicate it back to the user, which helps them to know how hard the robot is gripping without directly touching anything.

Why we made it: By this project we wanted to learn more about haptic feedback and communicating the "feeling of touch" while controlling robots. This is especially helpful for tasks that demand percision when it comes to pressure awareness: like when handling delicate objects.

How it works:

1. Servo motors (controlled from a computer) move the arm and the gripper to hold an object,
2. The load cell inside the gripper measures how much force is being applied,
3. ESP32 sends the data to a computer in real time,
4. The computer displays the pressure, helping the user understand how hard the robot is gripping.
