Popsicle Stick Robotic Arm with Arduino

This video tutorial guides viewers through building an Arduino-controlled robotic arm. It is divided into two main parts: the physical construction of the arm and the circuit and code used to control it. The tutorial covers materials like popsicle sticks and servo motors, discusses degrees of freedom, and offers tips on cable management and gripper design. It also explains how to use sensors like joysticks and potentiometers to control the arm, with example code provided for Arduino programming.

What materials are used for the basic construction of the robotic arm?

• Plastic sheets and glue

• Wooden blocks and nails

• Metal rods and gears

• Popsicle sticks and foam tape

How many degrees of freedom does the basic robotic arm have?

• Two

• Three

• Four

• Five

What is a potential issue when adding more motors to the robotic arm?

• The arm becomes shorter

• The arm becomes heavier

• The arm becomes more flexible

• The arm becomes lighter

What is a cable-driven arm?

• An arm driven by hydraulic systems

• An arm driven by electric motors

• An arm driven by strings or cables

• An arm driven by pneumatic systems

Which sensor is used to control the up and down motion of the arm?

• Potentiometer

• Switch

• Joystick

• Button

What is the function of a potentiometer in the control interface?

• To adjust voltage levels

• To control rotational motion

• To measure temperature

• To provide a fixed resistance

What is the purpose of the Arduino servo library?

• To control LED lights

• To manage power supply

• To control servo motors

• To read temperature sensors

What is the role of the 'attach' command in the Arduino code?

• To specify the pin for a servo

• To connect the Arduino to a computer

• To start the Arduino program

• To initialize the power supply

How does the Arduino's map function assist in controlling a servo motor?

• It reduces the power consumption

• It increases the speed of the motor

• It maps input values to a desired range

• It converts digital signals to analog

What is the input range for the potentiometer reading in the Arduino code?

• 0 to 2048

• 0 to 255

• 0 to 512

• 0 to 1023
