External jack connector to use power adapters from 6V up to 12V output Add Tip Ask Question Comment Download Step 10: Snap the Head and Upload the Code The head have snap feature, take care of the cables and close it.We are a platform to facilitate the development of new technologies, such as smart hardware, software, or wearable tech, that improve the lives of the elderl.
Otto was inspired by another robot instructable BoB the BiPed and programmed using code from another open source biped robot called Zowi. CC-BY-SA Ottos differences are in the assembled size (12cm x 7cm x12cm), cleaner integration of components and expressions. Using off the shelf and 3D printed parts, simple electronics connections (almost no welding required), and basic coding skills, you will be able to build your own cute Otto friend in as little as one hour Otto is design using Autodesk 123D Design initially and now is owned by TinkerCAD software you can modify it for customization or further improvements This instructable focuses on how to build the basic Otto DIY version, check the other similar robots in our website and welcome to participate in our new OttoREMIXchallenge Add Tip Ask Question Comment Download Step 1: List of Parts Gather all the off the shelf parts that youll need for this assembly. Heres the list: 1. Nano ATmega328 2. Nano Shield IO 3. HC-SR04 Ultrasound sensor. Mini servo SG90 9g x4 (each one should come with 2 pointed screws and one small screw). V Buzzer 7. Dupont FF cable connectors 10cm x6. AA Battery case stacked 9. AA alkaline batteries x4. ![]() Smooth Criminal .Wav File Full Kit HereIf you think is difficult to find the parts, you can buy the full kit here and follow this video of how to build: Add Tip Ask Question Comment Download Step 2: 3D Print Settings Otto is very well designed for 3D printing, the files that you had downloaded are property oriented and centered, so wont give you trouble if you follow this common parameters: Recommended to use a FDM 3D printer with PLA material. Resolution: 0.15mm Fill density 20 For slicing and generating the g code for the machine free slicer software like Cura (If you are outsourcing the printing no need to worry about it) After printing you will need to clean a little bit the legs and feet areas that fix the motors. Add Tip Ask Question Comment Download Step 3: Read the Instruction Manual As mention in step 2, Micro servo motors come with 3 screws in the picture are now included and rearranged the parts number for easy reading. Remember to have ready your magnetized mini screwdriver. Print the.pdf instructions manual for convenience from our Wikifactory Add Tip Ask Question Comment Download Step 4: Foot Servos Assembly Put the micro servo inside feet and then push it inside, if is to hard maybe need to clean more the area with a cutter. Is very important to check that the servo is able to rotate at least 90 degrees to each side. After checking the movement use only the small screw to fix it. Add Tip Ask Question Comment Download Step 5: Fix Servos to Body Take the other 2 micro servos put them in the defined locations in the 3D printed body and fix them only with the pointed screws. Add Tip Ask Question Comment Download Step 6: Fix Legs to Body Connect the legs to the hub of the micro servo, important like the foot servos you must check the legs are able to rotate 90 degrees each side respect to the body. After verifying the alignment fix them using the small screws to the hole inside the leg. Add Tip Ask Question Comment Download Step 7: Fix Foot to Legs Taking care of the cables as showed in the illustration you should put the cables inside the slots of the body passing thought the hole of the legs. Once they are in right position use the pointed screws to fix them from the back. Add Tip Ask Question Comment Download Step 8: Head Assembly Start from the ultrasound sensor is important to pull out the eyes to the limit. After putting the Arduino nano in the shield, optionally you can weld the battery holder positive cable to Vin in the board and negative to any GND. Insert diagonally the both boards together facing the USB conector to the hole in the 3D printed head, then use the last 2 pointed screws to fix it. Add Tip Ask Question Comment Download Step 9: Electric Connection (Wiring) Prepare the shield, cables and buzzer. Then follow the diagram pins numbers and make sure to put them in the right position. You have at least 4 option to power your Otto: 1. AA alkaline batteries (1.5V each) that connected in series go to Vin pin and Gnd 2. AA rechargeable batteries (1.2V each) that connected in series go to 5V pin and Gnd 3. ![]()
