Unfortunately, I can't seem to access the wiki. Can someone help? :)

The error message I get:
Forbidden

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

So here is the entry page:
http://robosavvy.com/site/index.php?opt ... obobuilder

I have created it and placed a basic sketch for a structure.
Let's hear everybody's feedback on the proposed solution and then finalize the entry page.

Cheers.
Pedro.

As someone had already suggested, we've come to a point were we have collected so much technical info about Robobuilder on the forum that creating Wiki to compile everything starts to make sense.

Robosavvy has a Wiki system installed (DokuWiki http://www.dokuwiki.org )

The entry page is here: http://robosavvy.com/site/index.php?option=com_openwiki

I believe all Robosavvy registered users have read/write access to it. I've never used DokuWiki and I'm having a bit of a hard time trying to find out how to create a new section/namespace. If someone knows, please go ahead and open one for Robobuilder :) If not I'll look into it on the weekend.

Here is a rough structure proposal:

Robosabuilder:
-- wCK Servos
------- Mechanical Connectors
------- Servo IO ports
------- Servo (wCK) protocol
------- Servo torque states: torque applied, dynamic Brake, free motion
------- Position read/set resolution: 8 bit or 10 bit.
------- Specs: torque and speed, behaviour under different voltages
- Forum member ATH1 has also suggested linking to the specs of the ATMEGA processor used on the servos - http://www.atmel.com/dyn/resources/prod ... oc2486.pdf
He was specifically looking for rise and fall times on the communication protocol but I believe other information might be found there.
- Additional info has been exposed by ath1: the ADCs inside the ATMEGA are all 10 bits. When using a 10 bit position read or position move you access the full resolution of the ADC.
- The ADC for the analog port on the servo is also 10 bit but the firmware only reports the most significant 8 bits :(

-- RBC controller
------- Plaform types, custom platform
------- RBC models and differences
------- Info on Bluetooth modules
------- Info on Acc Sensor
------- Using additional DOF
------- RBC protocol - official and addendum: work by Raymod, iBot and docs from Robobuilder
------- Custom firmware: sample by Robobuilder
------- Custom firmware: work by l3v3rz and phil

-- Head Part
------- Head models
------- Cable pinouts and connectors
------- Specs and pics

-- Custom Boards
------- Interfacing the computer with the servo bus directly (without using the RBC controller)
------- Other samples (I remember now the one iBot created to use a BT gamepad)

Please feel free to add and complete. I'm sorry if I left someone's work out or forgot to give due credit. If I did it was unintentional. Please jump into the thread and correct that :)

Regards
Pedro.
