3d Printed Robot Arm Arduino

3d Printed Robot Arm Arduino – MOVEO: A Complete Open Source 3D Printed Robot Arm We are pleased to present Moveo, an open source 3D printed robot arm, designed and developed by our technology engineers and the Department of Education of the Generalitat de Catalunya.

Technologies continues to make significant strides towards our goal of bringing digital manufacturing technologies to everyone. In this case, we present Moveo, a 3D printed robot designed from scratch and developed by our engineers in collaboration with the Department of Generalitat de Catalunya. The structure is completely printed using additive manufacturing technology and Arduino. The software controls the electronics. Our Sigma printer factory can produce batches for educational purposes.

One of the concerns of the Departement d’Enséniement is the high cost of materials that undergraduate students must use for their internships. Thus, an open-source robotic arm that can be modified by students and reproduced at low cost can cover many existing learning paths: mechanical design, automation, industrial programming, etc.

Technologies is part of the Fundació CIM and shares its educational mission. That is why, when the Departement d’Enseignement approached us last year and proposed this project, we did not hesitate to take advantage of this opportunity. Moveo allows educational centers to benefit from modifiable and affordable projects with sufficient results for training purposes, at a much lower cost than the industrial equipment they use.

After the robotic arm was designed and manufactured, we began the final phase of the project. This included the assembly of 15 institutions and refinement workshops around Catalonia, carried out in technologies. These organizations already have Moveo in their classrooms and workshops and must present practices that demonstrate proficiency with the equipment during the month of September.

As with all our developed products, Moveo files will be available to everyone. Thanks to the platform Github, a website where users from all over the world share their designs, anyone can find all the information they need to build their own movie or 3D printed robot arm at home.

So, in the files we upload to the platform, we include a “Bill of Materials” (BOM) detailing all the components needed to assemble the arm, as well as a CAD design, so that anyone can modify the Moveo design. according to their taste. Similarly, Github users will find STL files for printing hand structures and assembly instructions available in Spanish and English.

This Ai Robotic Arm Supports Modular Attachments That Can 3d Print, Laser Etch, Draw, And Even Assemble

Unlike our other technology products, Moveo will not be commercialized. The project was implemented with the aim of further contributing to society from the idea of ​​the Department of Education.

Thanks to this project inspired by the Departament d’Ensenyament and developed by Technologies, anyone will be able to create their own 3D printed robot arm at home without the need for high technical knowledge. We encourage you to create your own Moveo and show off your results on social media using the #Moveo hashtag. Build your first robotic arm!

This robotic arm is made almost entirely of 3D printed parts that snap together. It has three servo-controlled joints, plus a rotating base and mount. The arm is controlled by a series of buttons that connect to an Arduino Uno hidden in the base. A simple circuit makes connecting servos and buttons to the Arduino easy and quick to set up and assemble.

The arm is about 20 inches long, so it takes a lot of time and material to print. The parts are sized to fit on the Afinia H479 printer bed and several can be printed simultaneously on the same platform to save time. I used a resolution of 0.25mm and hollow fill for all parts (other settings were set to default). Additionally, I found that I needed to use a rafter to help secure the part to the print platform and to help the printer compensate for my table not being perfectly level.

Estimated total print time is around 32.5 hours, although as mentioned earlier it is possible to print multiple parts at once (estimated using Affinia software’s pre-print function – hard to calculate my actual print time. Still iterating with the project). Including the raft material, it uses 842.8 grams of filament, which means it can be printed from a one kilogram roll.

Most have “flat” sides facing the platform (see pictures). Many of them also have very delicate tabs for attaching cables, so be careful when removing rafters and supporting materials. First examine the stl file to see where the most delicate areas are.

Arduino code for servo control is very simple. The joints and bracket are controlled by a pair of servo buttons that increase or decrease the servo position by one step. The base is connected to the potentiometer, which is reflected in its rotation. Depending on the order in which you wire your buttons, you may need to adjust the code pin numbers.

I recommend that you check the code with your servos to make sure their limits match what is specified in the code. Testing the arms after assembly may damage or break them.

The same physical configuration can be used with different code if you want your arm to perform simple automated tasks. (Note that there is no positioning feedback, so the accuracy of the arm is limited by the accuracy of the servo)

Since the servos are located at different points along the arm, the cables must be extended. Just cut the cable and solder to the extension between the servo and the connector.

Next, make two sets of cables to connect the circuit board to the Arduino. The servo signal cable has male headers on both ends, each with 6 pins (per servo). The button signal cables also have male headers on both ends, but they have 8 pins (per button). Also, separate the two pins at one end from the other six, as they will plug into the opposite side of the Arduino.

A handheld circuit board is primarily a way to efficiently route various wires and signals, rather than a way to add more components. Start with the resistor, then the various connectors (note that some are female and some are male). Finally connect the connections.

Once you have your parts, you can start assembling. Start by pressing the microservo (with the longest extension cable) into the base of the bracket and feed the cable through the channel. Connect the 4-horn horn to the microservo and turn it to where you want it to be at the most “open” muzzle position. Push the straps, making sure the gear meshes. Bring the other microservo to the side of the bracket and assemble the rest of the bracket. The top of the grip has pins to help hold the claws in place and may require a bit of sanding to fit easily (try not to force them as they may break).

Connect the long parts of the arm segments with their cable channels and set them together. Insert the 4-prong servo horns and make sure they stick to the back. Attach the servo to its mount, making sure the main part of the servo is inside the arm segment (see photo). Connect the two halves of the bottom segment using small brackets. Thick brackets go to the sides of the segments with servo horns.

Assemble the long sides of the middle segment in the same way as the bottom segment, including the servo horns. At the muzzle, rotate the top joint microservo to one end and feed it into the microservo horn, keeping the parts at about a 90 degree angle. Do the same with the middle joint servo. This will align the servos so that their boundaries are symmetrical and the joints have a good range of motion. Attach a brace to one side of the middle segment for stability.

Starting with the still open side of the middle segment, gently guide the cables through their channels and under the tabs. To make sure that the swivel joint is sufficient, turn the part so that it is as far away from the cable channel as possible and tie the cable loosely. Continue to route the cable by carefully removing (and then replacing) the clamp to access the clips if necessary. If you use a tool that helps hold the cable, be careful not to twist or accidentally cut the wire.
