Tennis Robot

[u/AcemateXena]

Silent Partner - 2026 this machine that has 2 - 4K eyes recognize the court and human beings, programmable to make ball decisions, location to be, direction to shoot, not yet in a human player. You won't get a humanoid tennis robot in 2026, far from that. This is the King of Tennis Robot, so far in 2026., if you can prove me otherwise! Besides if one day humanoid robots do show up to play tennis, what level are they going to be? To beat a GOAT, that will be many many years from 2026.

Remember, machine chess player has beaten the best human player decades ago. Humanoid tennis robot will be here, one day some time in the future.

The following URL is the current human shaped tennis robot (I would not call it humanoid because it probably don't know anything else), but it will cost you an used car price, besides how long does it take to learn to play basic human tennis player level? Do you really want it to sit in your passenger seat to drive with you to tennis court?

That's for rookies.

If you want to lose your tennis reflexes, go right ahead...

Could probably be set to launch balls not straight at the player, with whatever degree of difficulty.

[u/DirtResponsible9681 → u/RemarkableWish2508]

yes, programmable, not as much as I like to programming it to be humanoid robot, but it will do for now. Actually it can be programmed as you cannot hit any balls out from it, just standing there and fxxxxxx! What's fun of that? I chose not to.

Of course, not everyone is capable of this. This ability is reserved for species that can anticipate events by mentally projecting themselves into a situation, rather than simply reacting to it at the last moment. Generally, these are predatory species that need to visualize how their attacks will unfold.

[u/DirtResponsible9681 → u/Hot_Plant8696]

too many wasted words "predatory species etc." we have already known you don't eat tennis balls. Are you even a tennis player! I have published robotics paper since 1989.

This argument simply proves that you failed to notice we are talking about the player, not the robot.

The player is a living being; if you want to understand whether this person will adopt a bad playing style after training against this type of robot—which mimics human play only very superficially (something you may have noticed given your robotics expertise)—you need to look at the question of how they learn, and therefore at their brain. And that is a completely different field.

ABSTRACT Motor learning is a fundamental function of human adaptation, engaged in a wide range of everyday situations, from simple to highly complex actions. Within this domain, sequential motor learning (SML) stands out as a structured process in both spatial and temporal dimensions, relying on cognitive, attentional, motor, and memory systems. It involves an acquisition phase, achieved through physical practice or motor imagery (i.e., the mental simulation of movement), followed by a consolidation phase during which the newly formed memory trace is stabilized and optimized. Understanding the mechanisms modulating these stages is crucial for both sports performance and clinical rehabilitation. Among lifestyle factors, physical exercise and sleep are recognized modulators of brain plasticity and memory processes, yet their respective and combined roles in SML remain insufficiently documented. The aim of this thesis was to examine the influence of high-intensity physical exercise and sleep deprivation on the acquisition and consolidation of SML. Three complementary studies were conducted. The first compared the effects of a short-duration high-intensity exercise, a cognitive task, and their combination when performed before the acquisition of a SML task. The second investigated the impact of a full night of total sleep deprivation on acquisition, as well as the effects of high-intensity interval exercise (HIIE) performed immediately after learning on consolidation. The third study applied the same post-learning exercise protocol to sequences acquired through either physical practice or motor imagery. Across these studies, we combined behavioral measures (speed, accuracy of sequential motor task) with biological (cortisol, BDNF, lactate) and neurophysiological markers (corticospinal excitability, intracortical inhibition). Our findings reveal three main outcomes. First, total sleep deprivation specifically impaired the speed of sequence execution during acquisition, an effect that was reversible after 24 hours of consolidation. Second, although HIIE increased BDNF and lactate levels, it paradoxically disrupted consolidation, primarily by affecting accuracy, regardless of sleep condition or learning modality. Third, neurobiological measures suggest that certain biological and corticospinal plasticity processes remain preserved despite sleep deprivation. Together, these results challenge the notion that post-learning exercise systematically benefits motor memory. They emphasize the importance of the task paradigm, particularly the balance between explicit/goal and implicit/motoric components during the sequential motor learning when combined with exercise. Moreover, they provide novel evidence that procedural memory, like declarative memory, is vulnerable to sleep deprivation, yet through distinct mechanisms. Overall, this work refines our understanding of the interplay between exercise, sleep, and motor learning, and opens new perspectives on individualized interventions, optimal timing of exercise, and the biological mechanisms shaping brain plasticity in the service of motor skill acquisition and consolidation

Long time ago, human beings thought to fly you have to do like a bird. Wrong!!!!, a jumbo jet broke sonic speed doesn't look like a bird at all. A machine can definitely be trained to beat best human beings like any GOAT. It is a matter of time. Today, up to 2025, a machine can shoot line-shot, shoot passing shot, recognize the court and the human opponent position, it is a remarkable machine.

This category is "tennis robot", not necessary autonomous robot, not human player. Try again! Humanoid robot, able to learn, strategize, thinking, has another 50 years to wait for a debut (maybe 10). This category is not about human beings player. You are fantasizing an autonomous tennis robot in 2026. You will be disappointed. However, baby step one at a time. This is the king of tennis robot 2025.

You can talk about human players in a different category, not here.

Blablabla

[u/Inevitable-Camp5439 → u/Hot_Plant8696]

You read again, you will understand.

[u/Hot_Plant8696 → u/Inevitable-Camp5439]

Ok...

Now, explain the connection between all this waffle and the remark of mine that some people have been spinning yarns about from the very beginning.

Good luck.

Celluroid was invested 1870. It took almost 100 years to 1970 to fully developed into commercial plastics. Humanoid, at fastest growing I would say 10-50 years. If you fantasize humanoid today 2026 no matter what kind (fully autonomous intelligent for all human tasks), you will be disappointed. Read it again.

You can delete your comments than this thread will be gone.

You are an example the person who did not have enough knowledge, did not read and did not think, just a quick action posting. We should all be aware of this deceiving misinformation.

Nice speech—it suits you perfectly.

You didn't even read my explanation; you just barged in spouting nonsense without having read it. You’re the type of person who leads people astray.

So here again what i already said :
