Servo Jumping On Initialisation

The dreaded jumping servo problem has arisen again - just today. All servos in the robot are HDD. The servo on port D0 now jumps after connecting, to about 35 degrees instead of 90 degrees. If I move the servo manually when turned off, the centre position is still 90 degrees, so the sprocket has not shifted. My INIT script has not changed. That...

Controlling Servos For Robotic Arm

Hello, I purchased this robotic arm (https://www.dfrobot.com/product-192.html#:~:text=DFLG6DOF%20is%20a%20bionic%20robotic,be%20rotated%20about%20180%20degrees) and wanted to control it via ARC. Should the servos be compatible? I also think it could have something to do my power adapter. I am using a 9V DC 800 mA adapter.

Hello Everyone, my first time here, I just started into robotics. I am looking to have the 8 X 8 RGB blink when my robot talks. I have tried scripts I found in the community on here, but since it doesn't connect to a digital port they do not work. I tried editing some of the scripts to use a sound servo to enable RGB animator script, but it still...

Ipad (8Th Generation) Ios 14.2 Not Launching ARC App

Hi,  I have purchased new iPads for each of my JD robots. It appears Version 2020.11.19.00 of the software is not compatible with these devices as the splash screen shows when launching the app but then closes down, however, double-clicking on the start button shows that the app splash screen is minimised to a thumbnail and hasn't actually closed....

Default File Storage Address For BLOCKLY Files

Hi DJ, just a brief question: How can I change the default file address for storing / loading BLOCKLY files within ARC ? I need to store and load them in / from my central server, since - over the time - I am working on three different computers and always updating new software versions on these three plus the server is simply a time consuming mess...

Detailed Explanation Of BLOCKLY Commands

Hi - short question: Is there a glossary for BLOCKLY commands ? Most are easy to identify, but e.g. what is the difference between the ADC command and the ADC12 command ? A survey for all BLOCKLY commands would be very helpful. Earlier I was programming OZOBOT EVOs, using OZOBLOCKLY and - I must admit - that they are offering a very good online...
