that robot is very basic, you can make your own. I almost completed mine already... let me upload some pictures in a while.

At current stage, fairly simple... PVC pipe 40mm + joint, 2 computer casing fan, balance from cut rubber, two voltage contral ( AC/DC converter ) some screws and nuts...




there u go, a partially finished robot... it can do bottom spin and top spin. It can also be adjustted to do sidespin as well.

ball will travel between the two roller and since the roller will be spinning, ball will shoot out when it get in between the two rollers..
the faster the roller spins... the more powerful the ball will travel.

Notice 2 rollers, if top roller spin faster than the bottom ones, it will produce a bottom spin, if bottom roller spins faster than the top one, then it will become top spin.

To incease the ball spin rotation, you have bigger difference of speed between the two rollers.

If you need side spin, just turn the whole thing sideways.


Things to do:
1. Auto Ball Loader... I am short of a round wheel
2. Mounting... I need to mount it into a casing ( some kind of box )

thats for the suggestions. At the moment my project is stalled because busy with other stuff.

For the auto ball loader, I have another slow moving motor ( geared motor ) which will push the ping pong ball towards the spinning rubber wheels.

Yes, it is a modified Computer Casing Fan. Its actually a 12cm PC fan, I cut off the fan blades, then wrap the fan center with table-tennis rubber. So you have a spinning rubber wheel. I have two of those rubber wheels opposite of each other and ping-pong ball will go in between those two. Because they are spinning, it can shoot out the ping-pong ball

it will have a motorized ball feeder, I am short of on more component.

got, blueprint was much much nicer than the actual product hahaha... unfortunately, alot of things cannot be achieved at the moment cos lack of components. My initial plan even have a remote control ( taken out from toy remote control car ) to control the speed of ball and spin. Project has been scalled down quite alot. Now only left with a skeleton ping pong robot ( even that also have troubles completing it )

it is almost completed already once a basic unit is done... can slowly enhance its capabilities, must make it in a very modular fashion. Too bad I have two very small kids at home, very hard for me to find time to do this robot.

Added on March 9, 2010, 1:55 pmActually I have thought if this, there is a big market locally. Cost of this ping-pong robot is quite low... I think until today, I spend less than RM50 on it. I think I can complete it within RM100.

I design this robot to be able to use battery and also power supply from the wall, it makes it very portable. Can even do ping-pong robot rental business... just bring it along to any place, with or without power supply, it can still operate with battery.

Even though u are in penang, can still work together on it... we can still share ideas to build this thing. You can always build a replica of what I build here in KL and I can build on what you make in Penang... we are still working on the same robot

Added on March 9, 2010, 1:58 pmwhat is a film slide rotator, is it easily available ? I wanted to have something like the sewing machine wheel, where it will have a rod pushing the ping pong ball towards to roller. I have a gear motor with me, which rotates very slowly ( speed can increase or decrease by varying the voltage channeled to this gear motor )

if you are looking for TBS, why not you try out TBS clone... Galaxy (Yin-He ) K4, it is cheaper and according to some people K4 and TBS plays similar.

or if you decide to go for all wood, I would recomend you Stiga Offensive Wood NCT

both are below RM150. I bought K4 for my nephew and Stiga Offensive Wood NCT for my brother from Yap's shop ( www.tabletennis.com.my ) and I have tried both of them both are very nice to play with. Decent power with decent control. Quality wise, they are also very good.

Korbel is a nice blade but at that price, better add a little bit more to get k4 ( around RM110 ) or Offensive NCT wood ( around RM140 ). I personally feels Korbel is lack of power.

you are right, Korbel is a pretty decent blade with decent speed. That time when I tested it, I was still using Sardius ... maybe thats why I felt a great loss of power. If compared to the Offensive NCT, I guess not much difference. As for the Galaxy K4, I feel is more value for money because K4 is a composite blade. Again, not everyone likes the composite blades.

yes, thats the one it is indeed a very nice blade like what they say in the reviews.

Added on March 18, 2010, 12:15 pmsorry that dont sell table tennis blade, it just happens that I help my brother to buy this blade ( OFFENSIVE WOOD NCT ) from Yap's shop.

I tried it for a while. It has a very crispy and nice feeling playing to play with. A very beautiful and high quality blade also.

I am so tempted to get my hands on the Tenergy, is it really that good ?

oh.. u are on bryce also nice... I was an offensive player in the past when I was younger, I use speed glued Bryce on a Butterfly Sardius. Nowadays, I tone down alot already, now I use Bryce Speed on KLH Special.

If you happens to find a Bryce replacement, do let me know. I will be very interested to try it out too.

Added on March 22, 2010, 10:27 pmit seems like the whole world is using it nowadays, surely there must be something very special about it.

Korbel is not a very fast blade, so you cannot expect to get much power out of it. It is good for controlled/placement game, not power game. Maybe you should try to play control instead.

Added on March 25, 2010, 5:33 pmwelcome back I just cant wait to play... hopefully can join u people one of these days. I hope I still can play after such a long break.

I am looking for a new rubber for my forehand, does anyone know where I can get the Palio Macro Era cheapest ?

This post has been edited by tsd: Mar 25 2010, 05:35 PM

since you are using macro era, is the grip lasting ? does it chip off easily ?

my setup, KLH Special + Bryce Speed 2.1mm and Inspirit Quattro Ultra Light 2.2mm is 175g

Added on March 26, 2010, 4:18 pmThanks... I think I will try out the Palio Macro Era 47 once my Bryce Speed gets worse, it is about 2 years already... Just now I tested it, it seems like still playable.

Ok thanks, u guys still play regularly at Sunway Club ?

I think I will delay my purchase first since my Bryce Speed is still usable, hopefully got new technology appear soon.

Not confirm yet, I am not sure when can I can go and play there. Maybe you can ask pingpang, cos I am not a club member.

here, read this http://www.amenclinics.com/cybcyb/exercise...st-brain-sport/

how wierd and what was you previously using ?

I was thinking of geting PME to replace my Bryce Speed.

hahah.. thanks.. like that I better strike out PME 42.5 from my short list. Maybe I will stick to Bryce Speed for my next replacement rubber.

My current bryce speed is bought in 2007, just now I just wipe it with water... bounce ball on it, still plenty of spin. Amazing rubber... almost 3 years arleady seems like still ok. Must take out for a few game then only decide to change or not.
