Hi. Its been a long absence because of covid. I’m back and will continue.
I have to reprint one of the pistonanticlock screws that go into the arm because the old one was angled a little. Then I plan to connect a Pi to the head and replace both arduinos with something that can handle multithreading. What about you?
I’m re-building the upper torso and shoulders.
My old printer was not well calibrated and I had a lot of dimensional inaccuracies.
With my newer printer, it’s now accurate, and since the stand for Fred’s new head is not that good, I’m using the upper torso as a stand 🙂

Cool. What do you have left to build?
Still working on the modified head, Last week I mounted the Raspberry Pi in the head, Friday I release the video on mounting the SMPS for the pi and connecting it to the PCA9685, the week after that is testing and some very basic programming.
Then i start the walking robot series I hope.
Where i plan to motorize the legs, this will not be an easy task.

Anyone working on their Robot today?
Been working it almost every day the last few weeks 🙂

I am using 5K ohm potentiometers and am thinking about changing it to 10K because the 5K is too sensitive for the Bicep Servo.

I power the NervoBoard with a Power Supply that is at 6V Constant. I’m not sure what was the root cause but I was able to replace it with an HS485B with no problem.
Possibly your extracted potentiometer that is damaged or a bad soldering on the potentiometer wires.
I figured it out. The MG 996R Servo was placed backwards and got hot and now theres a short across the motor inside the servo. Easy fix is to replace the motor.
I ran an example servo script that comes in Arduino Software to test the wrist servo and it works fine but when I use the NervoBoard to control the Wrist, it seems to not have enough power or maybe the impedance is not tuned correctly. I have the MRL Servo test sweeping from 0 to 180 and the wrist moves but just a tiny bit. Anyone experience this problem?
How do you power your NervoBoard?
Do you have a voltmeter to check if you have the correct voltage coming to the servo?

@bretzel59, What do you need help with exactly?
Do you have virtual meetings

We are turning Guile ON next week.
Thanks, we started in January working on Guile every Sunday for 5 hours. 52*5hours = 260 hours of building time. This time does not include 3D printing time.
Thanks Gael. We named Guile after you.
We are turning him on next week.
Are you working on motorized legs?
Can’t wait for motorized legs. My team will work on that next if you haven’t rel…[Read more]
Now I have a real clone of myself!
There is progress on the motorized legs, but I am still a long way to go.
Chances are that Vincent (bretzel59) will propose some walking legs before I am finished.
I’m trying to confirm the connections for the Finger Sensors and see that pins (14, 12, 10 & 8) are connected to ground and pins (6, 4 & 2) are connected to 5V. For example: Each finger has two wires, say main & return, if the main wire gets connected to pin 13 in the image below and the return gets connected to pin 14… then we do the same for…[Read more]
Here is how you must connect the two wires, if you are using the foam sensor with resistor:
More details here:
HOWTO FINGER SENSOR
In this exemple you are not missing pins.
Note: when you purchase the Nervo Board you get 3 sensor mini breakout boards.
2 boards are to connect to the Arduino Mega, and 1 is for…[Read more]
We named him Guile.
Welcome to Guile!

ah, ok thanks bro
I need permission – it says access denied
It hasn’t been working for ages.

I am having trouble adding our location to Google Maps. I requested permissions. I\’m trying again.

We use a variety of 3D printers ranging from Prusa to Monoprice

I bought the Nervo Kit but I see that the Hardware Map shows 2x Nervo Boards. I plan to use 2x Arduino 256 Mega which mean I need two Nervo boards. Is there any other PCBs I need to purchase?
You need two Nervo Board kits if you plan to use two Arduino Mega. No other pcb is required.
what print 3d you use?

Intel came out with this small compact camera that can measure distance with only one camera and an IR sensor. It could potentially replace the Kinect. https://www.pcworld.com/article/3020707/intel-to-ship-99-3d-realsense-camera-that-will-also-support-android.html

Is there anyone from Long Island, NY or around the island interested in building this robot?
I\’m forming up a crew to build the InMoov Robot. Long Island, NY will soon have one.
