Hi I'm 10 and am working on some other projects and am pretty low on funding whats your estimate for the cost $
thank you

No way! You can get everything you need from banggood or amazon for like $20 to or $30 max! No joke. That includes a board with wifi/bt, a 12 or 16 channel servo board and a cheap battery plus a bunch of servos.

TowerPro MG90S Servo x 8 / 50$ from ebay

so around 100$ for everything :)

Thank you for your estimate ^_^

im a bit lost here, i printed all part last week but now i dont find the same model listed anymore.
MOLD file wasnt there last week ? also the part i printed are not as discribed in the ASSEMBLE tutorial ://// damnnn

ps : ok found out the tutorial has been updated as well :) re-printing the new parts \O/ :)

Sorry about this, I just release version 1.2 yesterday, so still a bit confusing.

Version 1.0 Instructions can download from https://drive.google.com/drive/folders/0B63pt85qF_MYMlppUkpJMmpac2c

Version 1.2 improve leg1, servoBottom and bodyBottom parts.

its ok i re-printed the new part :) its printing so well thats great.
i try the hairdryer trick to bend the pieces but its not working that good :/ the edge of the 3d printed piece just melted out and the place im supposed to insert the servo arm is now curved, it worked, but its damaging the piece a bit :)

later tonight i will try and see if its not easier to separate the cross in two part, and print them on the side already bended, then clipse them.

two U printed from the side, might be a better solution :)

im unlucky so far with the legs, the first version seems to be too big to hold the arms and the new version (cross) doesnt work either, its too flexible now to hold the arms properly, i failed a bit at bending it properly. i will try to reprint the first version a bit smaller :)

Version 1.2 leg1 parts can tolerate more difference, If too much oppressive, just little heating can be adjusted.

i made another version of the legs cross, its smaller than yours, its printing right now, once its done i will see if it works better for me :)
i plan to use my dremel to weld both part.
here is the STL file (im not posting it becasue some holes are still missing for the screws)

ps : its a very ugly/dirty edit :/ im not too good at designing 3d objects

EDIT : YAY it works fine now, the arm are firmly fixed with my version. maybe my servos are bigger than yours, very strange it wasnt working with the other files :(

interesting design. thinking of making one of these. When I have time...

I love the aggressive look! Awesome!

Thank you ^_^

This will never walk, you need one more servo in each leg to be able to bring the weight close to the body when you lift a leg

Thank you for your suggestion ^_^

oh, i watched the video and at least it seems to crawl, good job

I will improve the robot action later ^_^

looks hot ! good job, any idea when u gonna release the code ?

Great news! code just released!

where did you found this board ? > TinyPlan V400 Servo Control Broad ? google doesnt give any result when i search for it ? :/

haha :) awesome, cant wait to test it, still waiting for my servos to get shipped
thanks a lot !
