If I want to rotate the arm and keep the end effector at the same starting angle (i.e., change in end effector angle = 0), the formula in the video would suggest a gear ratio of 2:1. That doesn't seem correct. Am I using the formula incorrectly?
if you want the end effector at the same angle, then it should be a 1:1 ratio, which is a parallel 4 bar linkage. at the same time i'm having slight trouble understanding the question so my answer might not be that helpful
@@notsaltysugar I am aware we could use a 1:1 gear ratio to keep the angle the same. At the 4:00 timestamp in the video, there is a formula to calculate the gear ratio based on the desired angles. I am validating the formula with a 1:1 gear ratio scenario and got a different answer using the formula provided. I am wondering if I am using the formula incorrectly.
Greetings, In your Fusion model, you show the arm and the end effector both rotating counterclockwise. If you are using a chain and the large gear is fixed, doesn't the small gear and the end effector rotate in the opposite direction, clockwise?
Nice demo and explanation
In your calculation example, 22/40~0.55, can you explain more?
