PM 1.0, Robotic arm with 4 degrees of freedom

thingiverse

The robot boasts two flexible arms, each featuring a four-axis degree system. The limbs are attached to a sturdy torso situated atop an already existing portable device. The mechanical claw is relatively simple with just two slender fingers. The project remains a work in progress and I am currently tackling the electronic component installation part.

Print Settings Printer Brand MakerBot Printer Name MakerBot Replicator 2X Infill Setting 30% Rafts and Support No rafts are necessary but use supports when printing arm parts, they really help stabilize them. The print has been done with minimal adjustments. Supports may be needed depending on part complexity. Post-Printing Requirements You will need parts for the main torso unit: 1 Torso Base Plate 1 Torso Top Section 1 Front Panel Part 2 Sides Panels Part For ease of production I used acrylic material sheets for these elements and it worked out fine, considering we could machine them quickly using standard machining methods. The sheets were precision-cut by a laser. An additional Torso part called "Base" is designed to be printed on the 3D printer but as yet I haven't found time to run that particular print job. You will need following components for one single robotic arm: 1 Shoulder Mounting Section 1 Upper Arm Component 1 Forearm Link Section You can order these servo horns, they match with my model https://www.servocity.com/html/146sh_wheel_arm.html HS-755HB Servo Motor, purchase it at: https://www.servocity.com/html/hs-755hb_1_4_scale.html
