I'm designing a bot for a TDP(Team Documentation Profile) for a competition which is supposed to throw a rugby ball. Since the deadline is closing in soon, I can't test things out myself.
After going through multiple ideas, I settled on using two wheels throwing mechanism.
Can I implement the above-shown mechanism without using rotary encoders for the two motors?
Basically I just want to ask if the two BLDC motors have any difference in angular velocity even when powered with the same voltage.
