EZ-Robot JD Shoulder Servo Not Rotating

Thanks, I have the Bing Speech Rec skill working. Now, I am noticing that JD's right shoulder isn't rotating anymore, so Stand from Sit doesn't work correctly, any movement that rotates the right shoulder. It can't be a wiring issue as that is internally wired, if I am not mistaken. Can you provide any troubleshooting on that new issue?

Connecting EZ-Robot Iotiny Issues

Hello everyone, I am new to using EZ-Robot, and I'm having trouble connecting my EZ-Robot IoTiny controller to my computer via Wi-Fi. When I attempt to connect, the computer's Wi-Fi connection shuts down, and after a few minutes, the EZ-Robot connection drops, causing the computer to reconnect to its original Wi-Fi network as if the EZ-Robot...

Robotics Project Help And Suggestions

Hello, I’m new to robotics and have been dreaming of building a robot since I was a kid. However, I didn't expect it to be so complex! I have some basic electronics knowledge and tools, including a multimeter and a basic oscilloscope. My current project involves a tracked robot chassis powered by two 12V Hall effect motors. I also have two R6DOF...

Windows 11 TTS With ARC

Can ARC utilize the Windows 11 Text-To-Speech (TTS) engine in conjunction with ChatGPT, instead of the other TTS skills provided within ARC? This would allow users who are implementing projects on Windows 11 Single Board Computers (SBCs) to take advantage of the onboard TTS capabilities built into the Windows operating system.

Auto-Start Script On Iotiny

, is there a way to have a script on the IoTiny start automatically as soon as it's powered on ? i have a prototype of a small robotic arm, one camera, 2 servos connected to an iotiny, works fine. The idea is, the arm should move as soon as the iotiny is powered on. As far as i understand a project must be loaded and then a script will be...

Connection Control Button Color Change For Lost USB Connections

Hello,  In my ARC project I connect three EZBs mounted on my robot directly to the computer through USB, not WIFI. Recently while working through connection issues with one of my USB connections I noticed in the "ARC Connection Control" that if I lost that troubled connection it's button would stay green. This would indicate it's still...

Seeking Complete Python API Document

I'm in the process of refactoring my EZ-Script code to Python for my R2-D2 project. I have numerous scripts in use, but the good news is that I can refactor them gradually-allowing some parts to continue using the old scripting while introducing Python code to others. This incremental approach is quite beneficial! For this extensive task, I aim to...

question

Choosing EZ-Script Or Python Sleep?

Should I use the sleep(timeMs) EZ-Script API command in Synthiam ARC, or is it better to use the standard Python sleep function, such as import time; time.sleep(0.05)? I have been programming using the time.sleep() function, which is standard practice in Python for introducing delays in scripts. However, I recently noticed the sleep(timeMs) command...
