Вставка
- Опубліковано 19 січ 2016
- An open Hexapod project using LinkIt Smart 7688 + Adafruit PWM shield (PCA9685) + 18 SG90 servo
the body is 3D printed (STL files included)
All infomation are available at github.com/SmallpTsai/7688-he...
Also visit • Hexapod with LinkIt Sm... for another video
Note. Hexapod v2 is available at • Hexapod v2 - Linkit 76...
This thing's motion is so damn smooth. Hats off to you m8!
This is really awesome! Good job!
hey awesome build . thanks for sharing the project details:)
+TearDown thanks, hope you enjoy it :)
+TearDown My friend help to record another video, give it a shot! ua-cam.com/video/70pN0Rd0ca4/v-deo.html
Hello! I've tried make a quad bot with the same pca and arduino, it work but I've a power supply problem, and the servo make a lot of noise during the walk. (the servo are similar to yours) did your supply the power to the servo with pca9685 ora did you directly supply power? thank you man.
Will be better if add a canopy for the spider.
vi que o parafuro é M2 6mm de diâmetro mas qual o tamanho do parafuso?
Or the 5v pin also can be use as 5v power input?
+tony kao Yes :)
qual é a bateria para comprar? em âmpere ?
請問ㄧ下，7688的5V怎麼接的？沒看到你接了ＵＳＢ，還是你接了Ｖcc的3.3V?
+tony kao Hello, the power flow is: 2S lipo battery -- (8.4~7.4V) --> DC/DC Buck Voltage regulator (Mini 360) -- (5V) --> 7688 's 5V output pin. It can also power 7688.
+Smallp Tsai : are you jump wire to the USB 5V trace? how do you feed in 5V?
+tony kao Sorry didnt mention very clearly. Plz check the first photo on my github page, the 5V first goes to left side of Adafruint PWM breakout, then comes out from right side of it and then jump wire to the hosting breakout of 7688 and enter 5V pin of 7688.
+Smallp Tsai thanks, but still not understand, i know you use a breakout of 7688. i did check the pin diagram, it require 3.3V input and specially warning 3.3V only, there is no 5V input pin into 7688???
+tony kao there is a 5V output pin, it can also be used as 5V input :)
I made the whole thing but used pi zero w instead. The robot is not able to lift its own weight. Can you tell my what capacity battery you are using. I went for a 2s 2000 mah lipo
Hi, PratyS,
It's been a while, but it should be a 2S lipo with roughly 2750mAh,
like the one used in my new hexapod project, you can check it at github.com/SmallpTsai/hexapod-v2-7697
how the code worked? I'm also using pi zero w but having troubles with the code part. Did you use 2 PCA 9685 ?
@@zeke8120 yup
@@prat1024 would you mind sharing the code? I'm struggling with npm not happy about gpio pins
Ciao SmallpTsai.
Can you direct me to the solution of the following issue?
After following your instructions on how to transfer the files to Linkit Smart 7688, I launch the URL mylinkit.local/hexapod ... The page loads BUT it remains in "Connecting...", I never see "Connected"!
WiFi net is the same for both Linkit and PC, name is the same on the Linkit and URL...
What can I do to check the situation?
I also see you have a smartphone App to control the Hexapod... where can I find it?
Thanks,
A
