Patrick, That's great, he's better making baskets then me. My grandkids would love having a robot do that. They tried bowling with a WowWee Robosapien, but not very accurate. Steve S

hi steve S i had a robosapien v2 great robot.the bowling depents alot on how, much the batts are full.the fuller they are the better the trow. its amazing to see how strong the ez parts are.this is a long arm, with original parts.

Wow! What's the distance on that throw! Are you making a team? You have enough robots!

Nomad 6R · Answer

hi chelsea i like the consept ez robots alot.there is so much to learn.and yes i have a , few robots.the mecca gets a few movements more,like bending&turning waist. here's a video for bending waist.its allreddy improved with metal on the , horn.more to come soon.

Patrick, Nicely done. Is the robot's hand gripping the ball and releasing it, or is it just balancing? I have been trying to get my Roli to throw a ball for my cat, and have not been able to get the timing in the auto-position correct. It either drops the ball too soon, or lets go too late. Seeing your video I am thinking of re-working the arm so it can do an underhand throw where it doesn't need to grip the ball once it gets into position instead of an overhand throw. I hadn't thought of the idea since it is so low to the ground, but I think with the right combination of servos and EZ-Bit extensions I could make it work. Alan

hi alan he can grip the ball.for excample when the hand is gripping to long it will , release the servo.so it will not burn out.for the movement, i make all movements separt. 1-choulder up a little 2-underarm up hand open 3-close hand 4-underarm go's down (stand position ) 5-underarm go's up ( speed 5 fastes ) and open hand i used the original jd.hope these pics helps.

thetechguru · Answer

Thanks Patrick. I'll try to see if I have better luck with an underhand throw.

okay i have now ad the arret for the turning plate.so that it doesn overturn, the body backwarts.now back waiting for parts.

Nomad 6R · Answer

a little update.mecca gets his speakers x2

Nomad 6R · Answer

here is an update for the mecca turning waist.i need some heavy springs . i used 2 meat boards with a grove in and some ball bearings 10 MM here is a little video and some pics.center bolt and wacher and locker 12 MM i painted two layers on,used and some grease.i also reinforced the back side. i notest the wheels are not straight .i used a alu plate 2mm

Nomad 6R · Answer

here a little update. for now i have some turning waist ,not total as i though, it would be.but for such big robot ,it is save not to go to the max of bending, and turning with plastik from a meccanoid.due they are very thin. also he will get a second HDD in the front for the bending,these two servo, are going to connect on the same port wiht a wire for two servo's. that means bolt will do desame movement at same time.this is needed , if you use bending&turning at same time.

JustinRatliff · Answer

That is freaking cool!

Nomad 6R · Answer

hi justin it works very well.

Chelsea · Answer

Very interesting way to use those boards! I have never considered that type of application with bearing- smart!

Nomad 6R · Answer

justin the poping of the speakers is almost gone.i went from 8 OHM to 4 OHM

Dave Schulpius · Answer

You must have a small army of robots by now. I'm impressed. Nie work.

Nomad 6R · Answer

Hi dave. Yes i have a few robots Thanks

Nomad 6R · Answer

i notest when turning and bending at same time,the HDD gets hot. so i solved that wiht a second HDD and chorten the body.he wil get , a schotich shirt to hide these servo's.next thing to do ,is to make the wheels, and legs stronger.by adding another wheel in the middle.as you can, see the wheel base is bending in the middle from all the waight. anyone who is going to use the mecca,make sure to start with, making the wheelbase stronger.the plastik is very thin.so now , waiting for parts.

Nomad 6R · Answer

hi i bouth a second mini version of meccanoid,do i needed extra parts for the big, meccanoid.as an roboteer you will know there is something we all have. you cant use a broken robot,you wil try to fix him.and so i did. i made a G15 into a G15KSM .M stands for mini.there is one thing i dont understand,maybe some meccanoid builders wil now this,and that is the , controls written in the book.i see all kinds of colors ,but what does they mean.? how do i go from excample command mode into another? here are some pics.    one thing for sure is the motion maker.it sucks.its not even close to ARC.

JustinRatliff · Answer

The colors are the colors of the eyes if you built the robot by the instructions. It is your feed back to let you know what mode the robot is in or what action the robot is going to take or what the robot might be waiting on you to do depending on what you just had the robot do.

Nomad 6R · Answer

hi justin ah if meccanoid did understand my command,i can see it by the color of the eyes, that i am in the correct menu. so there are 3 menu's. command/settings/motions thanks for the link

Nomad 6R · Answer

ok some more testing whit speakers.here i have a speaker 8 OHm 86 DB i use a jack plug 3.5 MM the sound is amazing,no cracks or any ugly sounds. so am thinking to solder a female extention wire on the lotiny and see, how that works.here a pic and chort video in german language.
