• Servo Motor - gives your robot the ability to move.
• Servo Motor - It uses a built-in rotation sensor to accurately control the motor’s output shaft.
• Touch Sensor - has an orange tip known as a push button, which provides the touch feature.
• Touch Sensor - When pressed, the push button moves backward into the sensor and sends signal to the NXT Controller.
• Light or Color Sensor - is capable of measuring the light intensity.
• Light or Color Sensor - It determines the brightness or darkness of its surrounding area and its surface, enabling it to identify different colors.
• Ultrasonic Sensor - can detect an object by determining the distance between the sensor and the object, allowing your creations to “see.”
• Pegs - sometimes called Pins
• Pegs - are used to fasten LEGO parts together.
• Pegs - are made in such a way that they can easily be inserted and removed from a LEGO hole.
