Paper / Book Outline for 3D Printing of Humanoid Robots
B. What is a humanoid robotics and why should you want to build one.
6. Watch videos of the DARPA DRC robotics challenge to see why robots need a human shape.
C. What are the benefits of 3D printing out a humanoid robot?
D. Why I started 3d printing out humanoid robots.
E. Why start with an open platform robot.
II. The road traveled or a brief history of how I got here.
C. I can print out a robot now! I now regular print out all of my brackets on my personal UP Plus version 1.2.
III. Servo selection.
3. Your servo will have two servo horns one on each side usually. One will be powered by the servo and the other will be free spinning.
B. Servo selection factors.
3. Speed of servo.
5. Metal gears vs. Plastic gears.
9. Will you have to make your own servo horns?
C. The servo type selected will then tell you the robot size and
c. MX-28 between 2.5kg and 4 kg.
D. The servo you select can make or break your robot project.
IV. What other hardware or software elements do I need?
A. Servo controller.
B. Programming software.
C. Higher level brain then the servo controller.
3. If you are following RoboCup rules then you can only add sensors that a human has. Allow sensors are eyes (camera), ears (mic) and a way to communicate between robots (Wi-Fi).
8. Mic for voice commands.
V. Moding and creation of the brackets and body covers for 3d printing.
A. Open platform robots benefits.
5. Hopefully it has Good documentation.
B. What is a robot bracket?
3. The brackets will be connected to your servos by servo horns. There is one horn on each side of the servo. Usually one side is powered by the servo and the other side is free spinning.
C. Why does my robot need body covers?
D. Best CAD programs to use.
E. How to create a .STL file.
4. Eliminate as much bridging as possible
A. 3d printing on your own personal 3d printer.
B. Printing out the robot through Shapeways and I,materialize 3d printing services.
4. Show how by pictures and diagrams how to upload a design to both services. Also how to start-up a store in Shapeways and how to get the parts into the BETA program.
C. Sharing your robot design.
D. Tips and tricks I have learned while printing out my robots.
5. I also keep my house closed and use the best air filters you can buy because of my allergies. This keeps dust from collecting on your filament.
4. Carbon nanotubes, pros and cons for robot brackets. Adds increased strength and toughness to ABS. I have just started to use this filament.
7. Too much flexing of a robot bracket when the robot moves can lead to increasing oscillations of the whole. This will then leads to major failure of disastrous results.
VII. Building of the robot.
A. So how do I assemble the robot
4. Sometimes you will have to disassembly part of the robot to assembly another part. Then you will have to reassembly the parts again. This is where documentation and pictures will come in handing. So you can show other people how not to make the same mistakes. For example the DARwIn-OP manual is full of small mistakes on which parts to assemble first.
B. What tools will you need?
5. Pliers set.
C. Fasteners or glue.
D. Zen and robot assembly.
2. Lock-tight can help keep screws from coming louse but the lock-tight will damage plastic parts.
VIII. Intro to robot programming.
B. Create basic movements.
4. Lower body movements are the hardest to get right.
IX. Testing of the robot leads to improvements (iteration).
A. what is iteration and why it is a great tool.
B. Think of testing as playing with your robot.
C. A robot competition is a great testing ground for your robot.
D. Share your robot at your local hacker/maker space or Maker faire.
X. Future ideas and ways to print out humanoid robots.
A. Metal printers.
2. As robots get bigger, stronger and faster than so do brackets need to get stronger and tougher to.
B. Resin printers.
C. Better tougher and stronger plastics for FFM printers.
D. Flexible and non-flexible plastic in the same print.
6. A part of the bracket can be flexible, while other parts can be rigid.
3. Soft to the touch.
A. DARWIN-MINI project.
B. DARWIN-OP project.
C. BIOLOID-3D project.
D. 4 servo robot project.
A. There is a synergism between robots and 3d printing.
B. The future is only limited by our imagination.
C. Humanoid robots among us.
