Spider Bug Robot(quad robot, quadruped)-MG90

thingiverse

It's done: I made a [BTRemote](https://www.thingiverse.com/thing:4192030) for this Check it out :) Update 2020-Feb-14: Finally I consider the Hardware part of this project "done", given the results it can get. The next fragile thing is the moving-software (and that is an endless story, hehe). To navigate through the parts a bit: I now have 3 bottom parts, you need only ONE of it: 1) Body_D_L_Screws: needed for Body_U_L_PCA_Neck Body. Quite open frame to fill as your needs. 2) Body_D_Cap_V2 matching Body_U_L_PCA_V2, Quite open frame on one side, "mesh" like structure on the other. fits the not any more used 4*AA holder. Keeping it as you might use it to make your power-train in there. 3) Body_Bottom_Lipo. matching Body_U_L_PCA_V2. Quite closed frame to protect the High-current capable parts from sinking the body on e.g. screws to go up in flames. I'm using that one... Updated Description and Schematic with latest StepDown converter. Update 2020-Feb-9: Added BodyBack_V4_Higher. It allows to do a filament change at specific Z to make a colorful Spider-Accent. Update 2020-Feb-7: upload of source code https://github.com/kasinatorhh/BTSpidey . Schematic updated: servopin use on now a INTerrupt pin. Old connection conflicted ISRs with SoftwareSerial for bluetooth. Mignon Batteries are a bit too weak: A stalled servo can eat up 700mA, peaks to 800mA sometimes. using new Lipo and StepDown. See below... Update: Completed Assembly Guide This is a rework (finally all parts are redesigned) from the original Quad Robot, Quadruped. Changes: 1. Added canals for Wires in the legs 2. Added more space to allow MG90 servos (but SG90 servos will also work, they are shorter) 3. widened body to allow more components, e.g. 4-AA-Cell battery pack. 4. added holes for PCA9685 Arduino I2C PWM board 5. lifted lower holes to prevent scratching on the table when putting in screws 6. Designed a Cable cover Spider Back to hide more cables. 7. Added my Ultrasonic Ranging Head (see my other designs) If you are interested on the .ino file (using HC-05 Bluetooth+Arduino Nano), please leave a comment. it took some time to rework the publicly available code.
