Chatgpt Slow Response Issue

I am experiencing a very slow response time when using ChatGPT within the Synthiam ARC software. It frequently times out after approximately 15 seconds. I notice that during the processing of my request, the message "Sending Convo request 44 msgs (0 images)" is displayed. Could anyone explain what the "44 msgs" refers to?...

I've been toying with the idea of installing a second personality generator skill in myARC project that operates three EZBs in my robot. While I haven't actually installed a second one, I "think" ARC may allow me to run two of these skills simultaneously. Please let me know if I'm wrong.  WHY? Well, I have many scripts in the one...

Ultrasonic Sensors Troubleshooting And Alternative…

Here’s my project setup: I have a lawnmower that stays in a small garage. As soon as it moves outside, a camera mounted on the mower should rise using a scissor lift. The lift should move up when the mower leaves the garage. My idea is to use an EZ-Robot ultrasonic sensor to measure the distance from the side walls: If the distance is below 40 cm,...

Understanding Servo Position Limits

, I am trying to understand the purpose of setting a servo's minimum and maximum positions within an initialization script in Synthiam ARC. For example, if I set Servo 1's minimum position to 20 within the initialization script and later in another script attempt to set Servo 1's position to 10, will the servo continue to move to position 10, or...
