I fixed the broken parts form last video and moved a glass of water. I also started building a new case for the electronic. For this I used laser cut parts, I made in the local Fablab.

Hallo Andreas,

Hallo,

Nach einigen erfolgreichen Projekten mit 3D Druckern und CNC
Fräsmaschinen (alle mit Arduino mega 2560 und Ramps1.4)möchte ich nun
einen 5-6 Achsigen Knickarmroboter auf Basis eines Industrieroboters
bauen.

Ich möchte dazu auf jeden Fall Schrittmotoren mit Getriebe verwenden (OSM Gear Ratio 14:1 Nema 17 Geared Stepper Motor 1.7A High Torque
) und bin nun auf der Suche nach einer günstigen Lösung für die Steuerung um
dies umzusetzen. Am liebsten wäre es mir wenn ich dies auch wieder mit
dem atmega 2560 und Ramps 1.4 (5achsen) hinbekommen könnte.
Es gibt viele Projekte mit Servos aus dem Modellbaubereich, dies möchte
ich aber auf keinen Fall.
Leider bin ich auf dem Gebiet der Software eine Niete und weiß deshalb
auch nicht wo ich eine Firmware herbekomme und wie ich diese
konfigurieren muß, das zum Beispiel alle 5 Achsen einer Richtung folgen.

Ich würde mich sehr freuen wenn Du mir helfen könnte, da Du so etwas
schon gebaut hast. Ich bin über jede Idee für Hardware, firmware und
natürlich auch Software zur Steuerung dankbar.

LG,Frank

+Andreas Hölldorfer for the magnetic encoders, for mine they sell press fit magnetic targets (axial and radial) that goes over a 10mm shaft. Your chip/sensor can then be mounted axially or radially.

Hi alle, Ich bin gerade dabei rund um den Roboter Arm eine Firma zu gründen, wir wollen dafür sehr kurzfristig an einem Pitch-Wettbewerb teilnehmen. Währe cool wenn ihr für uns ganz unverbindlich abstimmen könntet:

I stared making fingers for the OpenHand. I will use the is with their cupling system for my robot arm project:

Your 3d printer has just one extruder, right?  I was wondering how close you could get to this design using a dual extruder (Nylon or ABS + Filaflex).

Some preview of my new base, that houses all the electronics of my robot arm. A new video will follow soon.

This is an update of my robot arm project. The arm is now moving and gripping. Controlled by an Arduino Mega connected to a PC with a wireless gamepad.

Hi Andreas, I am interested in your project and I have (at least for now) two questions:

1. The orange base has a distinct design to blue, My question is, the other orange parts change your design or They are equals that blue parts. 

2. The encoder, you use a AS5045B, I have seen your Printed borad, but I don´t know that are the two elements that you connect a the AS5045B, Are they magnets?¿Could you tell me?

Thanks you very much

Got my Leapfrog yesterday, a few more tunings and the first real thing I will try to build is exactly this robot arm. Thank you so much Andreas. :-)

I made another video and talk about the progress I made and some broken parts.

Looking good Andreas! That "spider" on the bottom of the base joint looks like a big weak point. I'm sure next week you'll have a new printed shoulder and have it picking up your coffee! Keep up the good work.
