Custom Spider Robot MG90S servos - removable battery V2

thingiverse

This Spider Robot is a customised version of https://www.thingiverse.com/thing:2801781, but this model uses better metal MG90S servo motors. The 3D printing files were created using the Thingiverse customizer. https://www.thingiverse.com/apps/customizer/run?thing_id=2801781 The print was made with Creality 3D White 1.75mm PLA Filament and an Alfawise U30 PRO 3D printer. <iframe width="560" height="315" src="https://www.youtube.com/embed/P_-mOeMn0j0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe> Resolution: 0.2 mm Infill: 20% The body of the Spider Robot was created for a 18650 battery holder (https://namerre.hu/go/bg-18650-battery-box-rechargeable-battery-holder/), but after printing, I decided it's better to put electronics inside instead of batteries because the MG90S servo motors can handle up to 5-6V. So, two 18650 batteries cannot be an option for this Spider Robot due to the 8.4V. Finally, I used four AA batteries. Here are the things I've used to build the spider robot: 1. MG90S Metal Gear RC Micro Servo (12) 2. Arduino Nano V3 ATmega328P 3. 4x AA Battery Holder 4. PCB board 5x7cm 5. 2.54mm Male Female SIL Socket Row Strip PCB Connector 6. M1.6 3mm Stainless Steel Cross Pan Head Micro Screw 7. M3 x 30mm 304 Stainless Steel Phillips Pan Head Screws You can download the code from here: https://drive.google.com/file/d/1NCmxF01tO6k_sTeNk2PhlksFBAeEn8p-/view
