Modifying a CYS-S8218 Servo

Ray.Edgley's picture

The CYS-S8218 is a nice beefy servo boasting a 40Kg of torque, which is very impressive.

However, this servo does come with one limitation; it has only a 90 degree of rotation output.

When you look inside the servo, there at physical stops at 220 degree and the position potentiometer is also rated to 220 degree, this suggest a lot of reserve capacity within the mechanics, and the manufacture wanting to prevent model builder from overloading the servo by limiting the range to a point it will always have max torque available.

Walking Robots Part Two

Ray.Edgley's picture

In my previous blog on walking robots I touched on the current open source walking robot progress.

Since that time there has been some progress, with some success. 
Gael Langevin has released a video of his robot knee in operation,

Harland has also shown his robot taking its first steps

I can't figure out how to set Inmoov to start on camera 2. It always starts up on camera 0 which is my tablets rear camera.

CMUcam5 Pixy - first impressions

Gareth's picture

Here is some test data that I am working on to check out the capabilities and speed of a CMUcam5 Pixy camera.

I am using two interfaces to set the system up :-

1. USB plugging into the Pixy allowing the PixyMon Gui to monitor,adjust & capture objects (by colour).

2. A connection between the Pixy<> Arduino on the 6pin ICSP port (aka SPI (Serial Peripheral Interface))

listened to Ray and added weight

harland's picture

the ankle rotation needs to be redesigned as they are very unstable with added weight

am using 805 servo motor for ankle rotation which has trouble holding the position

I like using dc motors with encoders controlled by the roboclaw module which are much better

you can set speed, acceration and location (position) in rpms  (have 6 on 2 legs)

I need to smooth out the code, I have a lot of wasted movements in the walk

I am running the dc motors at 1500 rpm, think they can go to 2400 rpm

Hello Firends ,

Any idea on how to get android Speech Recognition work with programAB without webgui ?



voice command trigger with robot name only

sunilskar's picture

Hi Inmoov  Core Team,

I am facing problem with myrobotlab that robot hearing background noise and interprting  it as a possible command. or Give random answer. plus many time it take his output sound as input command.

Is it possible to incorpate a "trigger word" into the voice command? The program would have to hear this word before interpeting the command.
