Skeebot humanoid robot
Description
Skeebot Is A Work-In-Progress Humanoid Robot; The Goals Are .. - Inexpensive - Uses Readily Available Micro Servos - Reasonably (But Not Overly) Expressive; Ex: Should Be Able To Walk, Kick, Wave Arm, Grip Things Between Arms .. But Not Intending On Adding Gripping Rotating Fancy Hands Onto It - A Good Fun Size, But Not Overly Large Or Small; Should Be About 10" Or So High When Done See The Uploaded Images For The Shoulder-Clamp + Armbox (Servo Box) + Hand-And-Clamp And Prototype Torso. The Legs And Head Are Coming .. My 3D Printer Broke Down, So Just Need To Repair A Few Things To Test Those Components. Edit: Current The Torso Is Just An Empty Box (To Contain Battery And Electronics Soon); As You Can See In The Printed Photo Before I Blew A Couple Stepper Drivers, The Arm And Shoulder Are Working Very Nicely; The Arm Can Rotate Around In The Shoulder, Move At The Shoulder, And Move At The Elbow, Quite Nicely. The Leg Is More Or Less An Arm Right Now, With A Foot Instead Of A Hand .. Though The Feet Need A Lot Of Work Yet, And I Need To Start Writing Code To See About Storing Actions And Making It Walk, Rather Than Just Flailing Around Like A Crazy Person. But It Does Work :) Electronics -- I Use My Own Homegrown Pcb To Drive It, But Any Servo-Driving Capable Electronics Should Do (Arduino, R-Pi, Whatever.) Currently The Torso Is Just A Printable Box That You Might Be Able To Fit The Electronics And Batteries Into, But Currently As I Design It I'M Using An Umbilicle Of The Servo Wires Out The Back; Once I Have The Body Done And Working Okay I'Ll Resize The Torso To House The Electronics Standalone. (Ie: I Am Worried About Balance And Such Once The Electronics Are All In There, As Balance Impacts Walking And Bending And Such, So Will Worry About It Later .. Famous Last Words :) Servos -- I Use The Emax Es08Maii Servos -- Very Small, But Strong And Metal-Gear. Analog Or Digital Is Fine. The Es08Maii Are About $5-$7 Usd Or $10 Cdn In Common Locations (Such As Rc Hobby Stores). Shop Around Online! Plastic -- I'M Using Pla, But Abs Or Others Should Be Fine. It Works Fine With The Pla 'Threaded' Usual 3D Printed Look, But With Abs You Can 'Gloss Finish' It Pretty Easily, Too. Scad Files -- .. Will Upload The Openscad Files And Customization Instructions Later On, Once I'Ve Retested A Few Builds. I'Ll Have To Work On Some Devo Videos And Tutorial Videos Once Its Done, But That'S A Ways Off Yet :) Tools -- Not Much Is Needed, But You'Ll Probably Want A Rounded File; Ie: Theres No Way To Avoid A Bit Of Overhand On The Armbox Or Some Of The Other Parts, And If It Droops A Little.. Just Hit With The File To Make Sure The Servos Or Axles Fit In Place; Its Designed To Be A Fairly Tight Fit For The Servos, So They Lock Into Place And Make Everything Move Nicely Without Any External Screws On The Horns, But We'Ll See. In General, I Use Only A Couple Scad Files, But There Are Variables Defined At The Top To Tell It Which Parts To Spit Out, And Which Bits To Include (For Example, See The Photos .. I Can Include The Servos In The Display To Help Visualize Sizing, But When Printing Out Parts You Naturally Remove The Servos Since You'Ll Place Real Ones In There Instead.) Todo - Need To Round Off The Edges; The Hand May Rub On The Armbox When Waving Around, Say - Make It Adjustable For Other Common Servos (Ultra Common Sg90 Plastic Servo, Etc) - The Shoulder-Mount Is Currently Just A Cutout For The Servo Horn Cross On Torso, Which Is Fine, But The Arm Will Fall Off .. The Horn Cutout Needs To Only Be Half Deep (Say) And Have Some Screw Holes, But I Want To Tweak That Married-Connection To Be Stronger And Simpler - Etc Etc .. Lots To Do :)
