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.

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! :)

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.

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.

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.

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

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.

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.

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.

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
