Hi Dango,
It can be important to play players that push you and are better than yourself, however you can still get valuable training from players who are perhaps weaker than yourself or on the robot as you mentioned. A good mix i practice is important so making the effort to play with new and different players will certainly help improvement. In terms of getting better and improving its about focusing on key elements of your game that will make a difference, now obviously that’s individual to yourself but serve and receive are both huge factors as well as consistency of strokes.
For robot training, this is most effective when used to focus on regular practice to improve technique of the shots and footwork so make use of the movement capabilities of the robot and getting fast around the court while maintaining solid shots.
Hope that helps and any other questions let us know! Tom
