This is my very first instructable. In this one I have created a little robot to help market my high school robotics team 3802. This can be used as easy 3d prints for robotics competitions or as a key chain or a car mirror toy. This was designed in Tinkercad.
Things you will need:
2. TinkerCad (It's free)
3. 3d printer (If you want to print)
4. Filament for 3d printer
Step 1: Basic Body
The basic body is two box shapes with a set radius of 1.72. This makes the robot look a little less boxy in the end. The head is the same radius as the body and is scaled down in length, width, and height. Position the head in the center line of the body.
Step 2: Neck, Arms, and Legs
The arms, legs, and neck are all made from the cylinder shape in Tinkercad. The neck is fatter than the arms and legs and is positioned on the center line between the head and body. The arms are lined up from the center side positions from the body and are the same length. The legs are a equal distance apart from each other and have a small bevel change to 2.5. Make sure all the arms and legs are connected to the body and are on the work plane and not suspended in the air if you want this to print correctly.
Step 3: Face and Number
Adding the team number is just using the test preset in Tinkercad and switching it to a hole. Position it over the middle of the body and have it go about halfway to a quarter of the way into the body. The mouth is a thin box turned hole and about a quarter of the way into the body. The eyes are spheres stretched into ovals and are positioned in line with the legs are the bottom the robot.
Step 4: Hands, Feet, and Antenna
The hands of the robot are upright cylinders about the same height as the arms. Then create another cylinder but scale it down just slightly and turn it into a hole. The feet or shoes (you pick what they are) are rounded roofs presets from Tinkercad and are place upright on the end of the legs. They are taller than the legs but not too fat or else they will run into the other leg and foot. The antenna is a cylinder bevel 2.5 and is at a 45 degree angle to help the printing come out correctly.
Step 5: Key Chain Add on (optional)
To simply make this into a keychain all you need is the torus preset in Tinkercad and position it on its side as a hole in the middle of the body. Do not go too deep into the body or this could effect your team number or text on the robot. Then send to your printer and have the robot print on its back and there you have it. 3d printed robots ready for competition or keychains.
Step 6: Printed
After the print is complete it is ready for use and robot representation. The salt shaker shows the size comparison.
