take my comment with a grain of salt, i'm not very good at video analysis, and there is only 1 angle, i might be fooled by it as well
Here is what i have to say
1) the most striking thing, is that more than once, you totally miss the ball, you're just hitting air ! you have a sync / timing problem
2) the overall impression is that you are putting way too much effort, you need to be much more relaxed
3) not sure, but it looks like you might be a bit too close from the table, and hitting the ball too late / too close from your body. It doesn't help that the robot is setup so that the bounce is rather high, so it makes it a bit difficult to do a drive at the top of the bounce, too close from the table. The best hitting zone is in front of you, so it means you should hit those balls before the top of the bounce [and adjust the motion] or go back by 10-20 ?
4) swing is way too vertical, i think it should be more horizontal with a more closed angle. When you do you follow through, we can't even see your bat on screen any more !!!
5) you are using the rotation of your body and putting your weight on the right leg at the beginning of the motion, thats good, but i see you then putting your left feet back as you're doing the swing. nope, that left foot shouldn't move and your weight should shift from that right foot to that left foot. What i do to make sure the transfer is done, as i finish my swing, only the toes of my right foot are touching the floor, the heel is up. No way i could not go forward like this, if i tried to do something which looks like you, i would be falling.
like others said, there are plenty of tutorial videos on the net, just look on youtube or past threads
