For the servos, in order of left to right, the far left port is for the micro-servo for the gripper, next one is the upper servo, then the middle, then the two lower servos and then the base. The attached zip file at the bottom is the intellectual property of Instructables user Beaconsfield.Īdding the Circuit is fairly simple, it just consists of adding the buttons and eventually the servos to the circuit board. It is NOT a simple program to use.įor convenience, it is probably a good idea to print pieces by arm section (gripper, base, etc.) so you can work on assembling that section while other pieces are printing. Either get experienced using Meshmixer to print pieces or have a someone who already is do it for you. It is recommended to use the Meshmixer program to automatically create supports for these kinds of pieces. ![]() Each piece with an overhang (a part of the piece that hangs over air) will need additional supports in order to finish printing. It is recommended to print pieces using the recommended infill density (listed below) to minimize breaking or damaging pieces. To minimize frustration, please print using a sturdy and decent quality filament. This process will take a week at minimum to complete, and most likely several accounting for damaged pieces and failed prints. 3D Printer (We used the Makerbot Replicator 2)īy no means are the specific products linked required in building the arm any standard part should suffice.Īfter the lengthy process of assembling all your materials, you will now endure an even lengthier one: 3d printing the robot arm parts.A decent computer to run and upload Arduino code.Spool of Filament(PLA or ABS) ($25.00 to $40 approximately)įor the robot arm functionality, you will need access to:.6 Servo Horns (Must fit BOTH mini and standard servos)(approximately $0.40-0.50 each).Electrical tape ($6.66)and duct tape ($7.12).Included with each part(s) is a shopping hyperlink. ![]() As such, there are many, many materials that you'll need, as listed below. ![]() Building a 3D printed robot arm and programming it to move is undoubtedly on the challenging side of the project spectrum.
