I do plan on putting everything up on instructables.com, at the moment I am playing with different MCU's. I started with an ATMEGA328 and quickly ran out of memory, then built a version that uses a Teensy 3.2 with lots of memory but no connectivity, so I just ordered an ESP32 since it has bluetooth & wifi.

I just put it up, sorry it's taken so long! www.instructables.com/RGB-LED-Sphere/

The code is at the bottom of this page: www.instructables.com/id/QR-Digital-Clock/

To program the nano with the PixyProgramHeightWidth code you will want to use Arduino IDE 1.0.6 and the Pixy library to compile & upload the code to the nano. My guess is that the pixy library is missing from your libraries folder, which is why your IDE cant find pixy.h. I did not write the Pixy library but should be easy to find with google, download it and load it into your IDE and then try to compile/upload. Let me know if you have any trouble.

Hi David i follow your instructions and it work i was able to download the program to the nano, now i should mention that im using a botboarduino from lynxmotion and im not sure if im hooking the wires up correctly because you using a mega i connected the nano to botboarduino nano vin to 5v ground to ground and tx to rx wich is pin 0 in botboarduino but i dont think the nano is transmitting to the botboarduino in the nano only the red power light is on do this sound right to you thank you

@@davidhend ok i made it compile and upload to the nano but there is no comunication w camera or mega

hi david sorry for asking to many questions but now im trying to use the arduino mega but when i compile i get this error'cRRcoxaPin'was not declaredin this scope any advise thanks in advance

hello David success everything works finally after some error and trial but i do have one question the pan and tilt mechanism for the pixy is the program already in the nano would it work if i get the brackets for it thanks

The Mega is underneath the ps2 receiver on top, the receiver had two red LEDs. The UNO was small enough to put in the body of the robot under the camera. Hopefully that's clear enough.

I did have a little trouble, and the robot currently uses six HS-645MG and twelve HS-422's. At some point I will replace all of the 422's with 465's but you can get away with it for a while if money of tight like it was for me.

Jeremy Gilbert Same as you, managed to get the output from pixy and nano, but Arduino just freezes. I changed the sampling time to sample every 50 ticks, it doesnt freeze now, but doesnt respond too

Jeremy Gilbert You deserve a medal, Im gonna try it out tomorrow!

By the way, did you change pixy height/width or any other code files?

Hey Jeremy, did you manage to get any results with forward and back movement?

Could you send me the code with the changes you made, please? Thanks

The LCD was a 2.8" TFT Touch Shield V. 1.0 from Seeed Studio. I believe I purchased this one as a Radio Shack special. Not sure if Seeed Studio still sells V. 1.0 on their site though.

Sorry for the delayed response. That's really interesting, I believe the ssc-32 has an activity LED that lights up after each command is sent. Do you happen to see any activity on that LED?

hello do you think i can use a botboarduino to do this project

I would think so, however I have no experience with that board. Also the software will most likely be different but don't know the specifics. Since you already have the mega you could try writing a small program to talk to the SSC32 to move a single servo a set distance, it is really easy to do that. This would let you know if you have things wired correctly and the baud settings on the SSC32 match the mega. Good luck with your project and let me know if anything else comes up.

Thanks! You can find all that information at: www.instructables.com/id/Arduino-Mega-Hexapod/

thanks for the info

Hi David , im trying to get the code from github but having some problems im getting error and asking for ps2 library i will welcome any help thank you

Sorry, I meant to reply sooner but got busy and forgot. You will need to make sure to add the PS2X_lib library included in the GIT repository into your Arduino IDE. You will also want to read the readme that explains how to replace the HarwareSerial.cpp & HardwareSerial.h. Hopefully that makes sens to you.

thank u i will give it a try

in theory yes, but it would be super lo-res. I never got that far with mine.

Use GRBL i. Arduino

+_who_cares_ LOL : ) This project definitely stays at the office, it would be tough to pull off in the bedroom for sure!

+Jorge Marquez That is really wired that you are not able to access either, I just tired myself and didn't have any trouble. Hmm... If you cannot get the code/spreadsheet to pull up, send me your email address and I will send them to you. At any rate, I would think that the inchworms circuit board is similar enough that you could do the same.

+David Henderson my email is marquezjorge54@gmail.com thanks a lot!!!! I'm doing his for a school project.

송명용 The source is available at the following URL: github.com/davidhend/QR-Code-Generator More information can be found here in case you are interested: www.instructables.com/id/QR-Digital-Clock/ Have fun & let me know if you have any other questions.

David Henderson Thank you...

linkspyder The code for the project is available at the following URL: github.com/davidhend/Hexapod I would suggest looking at the readme file on that repository for a breakdown of what's what. The cable sleeving, is 1/4" expandable sleeving from Altex.com www.altex.com/14-Expandable-Sleeving-BSPSC140-P150861.aspx I cannot remember the exact sizes but the largest was right around 12"

David Henderson Thank you Mr.Henderson for your info. I'm trying to build something similar to yours; can u tell me if with this one you are also using a ubec 15A to power the system? what type of lipo are u using? thank you once again.

linkspyder So I am using two UBEC's; one for the servo controller & servos, the second powers the robot's MCU's and PS2 receiver. The reason they are separated is because the servo "noise" causes problems with the RF for the PS2 receiver. Both UBEC's are 8A but can handle bursts up to 15A. I got them from hobby king at the following: www.hobbyking.com/hobbyking/store/__6233__TURNIGY_8_15A_UBEC_for_Lipoly.html In regards to the batteries, for the servo's UBEC, I connect a 3S 11.1V 2200mAH Lipo battery; and a 2S 7.4V 1650mAH for the robots logic. Let me know if you have any other questions, I will do my best to answer them quickly.

David Henderson Thank you very much for the information and help. Still got one question :) for the ps2 controller/receiver can you tell me which version are you using? thank you

linkspyder I am using the V2 of the PS2 controller/receiver; which I got from robotshop.com. They also have V3 now; which I am almost 100% sure would be a drop in replacement for V2. I will leave that up to you.

gears strip before the motor stalls??? that sounds terrible! but the bigger the motors the more power they chew up, so it can be an unbelievable power bill running a stronger robot, all servos in parallel.

***** In order to facilitate walking, I used the parts from the quadruped to make a hexapod, plus extra ordered parts. I have also swapped to using a PS2 style remote control. The firmware is also different and allows for more control. In order to make the robot more interactive I added a "Pixy Cam" from charmed labs; I integrated it in such a way that you can train the robot to follow a color of your choice. Here is a video of the progress I have made so far: czcams.com/video/R6kvBNsAwWs/video.html To be honest I am not overly familiar with the Towerpro servo brand; and dont have any personal experience with them. I am quite impressed with the Hitec servos; I am still using 12 HS-422's and 6 HS-645MG's. Ideally you would want all HS-645MG's but the 422's work pretty darn well and really hold up to the abuse; haven't broke one yet. You could always order some the the towerpros and see how they work. I buy almost all my robot parts from robotshop.com, they have always been very reliable and easy to work with.

I sure was, they were good enough to move around and test code; but weren't strong enough for the quadruped to walk.

David Henderson Time to order more servos.....

Thanks you very much. I have seen the T8 and was very impressed with it; the look and feel of it is top notch. I love how thin and light weight it is, it would be fun platform to tinker with. That's funny you mentioned perusing the object because the same thought crossed my mind. I haven't tried to implement the perusing behavior but do have an approach in mind. When I do, I will be sure to put up a video.
