Speed Feedback

Present a method to make sure that the motors have the same speed

That's what I found about Speed Feedback "Feedback devices: Position Sensors Velocity Sensors Position sensors are the feedback devices used to find out the accurate movement of joints for accomplishing the required direction and position of the end effector. A robot requires velocity sensors for controlling the speed of the manipulator movement. Position sensors use several devices such as resolvers, potentiometers, and encoders for sensing the position, while the velocity sensors include dc tachometer for providing appropriate speed. Every single robot requires feedback devices for delivering accurate speed control. Even the recently developed complicated control system also hardly relies on these devices for gaining better performance of the robot manipulator in some tasks like deceleration and acceleration."

I also found something called Speed Sensor which is available on RAM Electronics for 45LE. The Speed Sensor can measure the rotation per second of the DC motor, so by knowing the number of rotation of each motor we can regulate the speed of the motors to make our car more stable as the motors don't have exact the same speed. We can also use it to make our car covers a certain distance ,that's what we'll need in phase three . Here is some tutorials on how to use it and its code: https://www.brainy-bits.com/speed-sensor-with-arduino/ https://www.youtube.com/watch?v=oQQpAACa3ac
