EV3 large motor
The EV3 Large Servo Motor is a powerful motor that uses tacho feedback for precise control to within one degree of accuracy. By using the built-in rotation sensor, the intelligent motor can be made to align with other motors on the robot so that it can drive in a straight line at the same speed. It can also be used to give an accurate reading for experiments. The motor case design also makes it easy to assemble gear trains.
×1
EV3 Medium Motor
The EV3 Medium Servo Motor is great for lower-load, higher speed applications and when faster response times and a smaller profile are needed in the robot’s design. The motor uses tacho feedback for precise control within one degree of accuracy and has a built-in rotation sensor.
×1
EV3 Sound Sensor
the Sound Sensor allows your LEGO® MINDSTORMS® NXT robot to hear! The Sound Sensor is able to measure noise levels in both dB (decibels) and dBA (frequencies around 36 kHz where the human ear is most sensitive), as well as recognize sound patterns and identify tone differences.
×1
Ev3 Ultrasonic Sensor
The digital EV3 Ultrasonic Sensor generates sound waves and reads their echoes to detect and measure distance from objects. It can also send single sound waves to work as sonar or listen for a sound wave that triggers the start of a program
