4 axis robot arm with a small gripper and teach function. (In fact: it is a 3 axis robot) This robot can follow. This robot can learn. And this robot can repeat endles. And he lost all his memory if the batterys are low. This makes it new all the time he is powered again. - The i…

Have you heard of baxter. I think your design is better. Dear: Pinaut You should know I am a big fan of baxter and your robot is a lot like him. Baxter is an industrial smart robot that can do almost anything. Maybe you should make your robot humanoid to resemble baxter, just sa…

Great Thanks so much for sharing and giving good explanation of algorithm approach.

great quite precise movements. why don’t you create direct interface with human hands and fingers? Great job anyway!!

Well, first of all, welcome Well, first of all, welcome to LMR. Your robot arm is something really cool, especially the learning option. You said he’s losing all his memory when powered down. Why not write those nubers in the EEPROM or add an SD card to your robot arm for lots …

losing memory Sure it would be possible write the recorded steps in a memory (the code writes data to serial after start playmode (for debug or later using)). But i’m fine with ‘no memory’ because … how should i say? … its the soul from this robot: Be something like ‘virgin’ or …

Soul, rebirth, fair enough. Soul, rebirth, fair enough. Still, he should remember something, at least give him a name :slight_smile:

Power problem (aka circut diagram?) As an early start on this, I tossed together the 4 pots and 4 micro servos, just wired (power wise) in serial to the 5v and ground on the Arduino. (through a breadboard) When running one pot and micro servo (and a quick wacked tougher piece o…

servo power While programming this project i run the (micro!)servos directly from the arduino mini powered by the usb port from my macbook. This has given ‘jumping’ and imprecisely servo movements. This is extremly non-serious ! Don’t do that with bigger size servos! After chang…

Servo moving very slow in Play mode Pinaut, thanks for sharing. I am just finished the wiring on the breadboard and have a question: does anyone have any idea why any servos move very slow in the Play mode? very slow, like 10 seconds for around 20 degrees. The follow mode is fin…
