Hmmmm…
In this vid you have the robot to send the ball out a little slower... and it is BARELY going over net, often hitting it... and lands real shallow, then drops to almost table level by the time it reaches you. Ball is already on descent as it gets into your impact zone.
Given that height of the ball as it enters you optimal impact zone, you need to be 6 inches or so lower... because the is entering your zone already low and you are too upright to hit that ball effectively... and given your impact, it wouldn't hurt to let ball come into your impact zone some more. (although it prolly better to move forward and establish the impact zone so that ball enters at right height and depth)
Two ways to cope with such an incoming ball are to get down lower and explode up/forward... or move forward enough so the ball is net height minimum (unless you are gunna take it off bounce or on rise)… and other is to move position forward so ball is better placed in strike zone.
If you are dead-set on practicing this BH shot 1-2 feet off the table... you oughta set the robot to shoot the ball so it lands deeper... not land extreme shallow.
In a match, an opponent will give you a softer ball (or soft-slow spinny) that lands shallow when you are positioned too far back... such a ball quickly falls down before it arrives to your strike zone... you wanna crush it, but you have no position or leverage and are baited into an error.
You have to deal with this in a match, so setting your robot like that is good, realistic match practice to force you to recognize balls and adapt... but it is not a good way to groove your fundamental stroke vs light topspin.
Another thing to mention is the frequency of balls shooting out from robot is too slow. You have one shoot out... you hit... and are almost unconsciously hitting again before ball shoots out. Too much a pause from the last hit... it is an un-natural cadence too slow for matches or training... you have robot set to shoot one ball every 3 seconds... if you want to slow it down, have robot shoot out a ball every 1.5 seconds and see how that works.
