PLEN Playground - Forum

Hmm...

If you mind, upload the phenomenon on video sharing site (s.a youtube) could be helpful for me ;)

Hi High-Gi,

Could you try following steps?

1. Edit the latest version firmware for Arduino, and upload this one.
   (Before you install it, you need to change the value TARGET_DEVELOPER_EDITION at BuildConfig.h, to true from false.
   s.a. https://github.com/plenprojectcompany/P … fig.h#L38)
2. With the latest version Control Server, read the all motion files at PLEN2 repository and install these.
   (s.a. https://github.com/plenprojectcompany/P … r/motions)

If you have any troubles after doing that, please ask me again :)

Hi spacorum,

The old version control sever has confusing UI/UX...
"RESET" button means "Set a joint to degree 0", not "Move a joint to the home position".

I fixed this bad UI/UX on the latest version. Please try to use it :)

Hi gfrisoni,

Unfortunately, anyone hard to control PLEN2 via bluetooth enabled windows PC because native API has some bugs.

Also, many android devices have buggy API and buggy bluetooth device.
I recommend to try following answers:
- Turn off both switches of PLEN.
- Turn off Bluetooth function on your device.
- Shut down all applications' task which can connect PLEN series robots. (s.a. PLEN Connect, Scenography, and so on.)
   (If you can see the applications's task then tap square like button that places bottom of the device, you need to swipe them to horizontal direction to shut down completely.)
- Turn on both switches of PLEN.
- Turn on Bluetooth function on your device.
- Start up any application to connect PLEN series robots.

Just for reference, the topic could be useful for you ;)

Hi hipposen,

Just for reference, we usually use switch science's one as general AC adapter for PLEN series robots.

Hi, Kcwkam

Sorry for late reply X(

Since October middle, the motion editor employs new communication protocol.
If you want to use old file, it could be available to change properties of json file below:
  - (old) -> (new!)
  - func -> method
  - args -> arguments

Hi Hugo,

Just for confirmation, did you assemble your PLEN in accordance perfectly with the official assembling manual?
Timing of to turn on the switches is very important to assemble PLEN without any troubles.
(If you can attach a picture or a movie about your PLEN's status, it could help me to solve this problem.)

If did that, I recommend to reset the joints configuration in reference to steps below:
- Disassemble the all plastic exterior parts for safety. (Not necessary to detach the sevos.)
- Download any serial terminal to communicate PLEN.
- Start up the serial terminal with baud-rate configuration "2,000,000".
- After that, send ">JS$HP" commands text. (s.a. -> http://plen.jp/playground/wiki/specifications/protocol)
- Re-assemble the all parts.

Hi hipposen,

The control-board has 2 electric lines.
- One is for servo motors, it satisfies 6V - 1.5A rated (7V - 3.0A maximum rated).
- The other one is for MCU and ICs, these satisfy 5V - 0.5A rated.

Also, USB connector of control-board can only provide electricity to MCU and ICs.
Thus, servo motors don't move if you only connect USB Adapter to USB connector.

Hi, rocha

Thanks for really useful suggestion! I will consult this issue in electric circuit design team :)

Hi, akisaku

Whenever you would like to buy any parts of PLEN2, please let us know your inquiry via the official contact form. We can accept your order and then send the estimation.

Also, currently anyone can get the 3D model of PLEN2 that is implemented by Autodesk Fusion 360 ;)

Hi, rocha

The main control board of PLEN2 doesn't have a function that can development with USB,
but you can program it with edison board as a WiFi access point and using SSH protocol.

Please try following steps:
1. Turn on edison board.
2. Connect a WiFi access point that has SSID "PLENdev<RandomCharacters>".
3. Run any SSH terminal and login host as default gateway, with username "root" and pass phrase "plenproject".

If you would like to develop it with USB, please buy breakout board for edison or any compatible board.
