dear friends,
am from chennai, am planning to do a project as a robotic arm playing a chess against a human. for this i searched lots of site i got various arms all which i hav to import to my place (thats not a problem)
but i need to know will a robotic arm can pic and place the chess coins, will it be easy to do so???
i hav also seen the arms provided by lynxmotion. but my question is, all these arms r not more than 14-16 inches in length but the chess board may be not more than 12 inches in length or width and also the size of each square in the chess board will be max of 1.5 inches but can a arm will be able to pick the coins placed sequencly in 1 inches of gap? then the jaws of the arm will dash with coins near by??
if i plan to increase the space btwn coins then the board size will increase more than 20 inches then my arm cannot roam around the chess board to pick coins because of its length will be 14-16 inche??.
so frnds plz give me some suggestions regarding this where can i get lengthy robotic arm , or else arm with jaws less than 1 inch of closing and opening???
The robotic arm from lynxmotion extends to reach farther lengths. Also, you could try building a custom aluminum arm and get longer tubing for added length. I hope this helps. You type in a way that is realy hard to read (no offence).
Hello,
I’m a student from Italy, I just finished building a chess playing robotic arm with other students in my Univ. The cool thing is that it’s wholly built with Lego, and controlled with Mindstorm RCX kit. The structure of the arm is VERY weak, it oscillates when moved because of its slenderness. Lego motors haven’t got a reliable speed/position control, so we decided to feedback-control the arm using two webcams, keeping track of the hand position, to achieve a good precision in placing/picking the Pawns. The project has been quite complex, if u wanna informations about it, feel free to message me.
We’re using open source chess, GNU chess. Our interest was the arm, not the software
However we had to interface GNU chess with the arm control system, and develope tasks such as pawn moves recognizing.
We’re planning to build something else, and actually we like robotic arms
I was wondering if it’s possible to build a sort of high-performance arm with ur stuff… We’d like it to perform some strongly time-dependant tasks, like taking moving objects, and, why not, playing a VERY rudimental version of table tennis… Browsing ur site, I saw hi-torque servos, but they don’t seem strong enough. I mean, if I want a 50-60 cm extension (yes, from Europe ), taking into account the weight of servos, hardware, aluminium tubes, the torque required is quite high. The main problem is that all of your servos are designed to give a very fast response (like 60 deg in .12 sec, right?), and this penalizes the maximum torque given. A gear reduction would be the best solution, but I read that those servos’ rotation is limited to 180°…
Have u got any suggestion?
Thank you, bye bye!
