Alternative To Ezrobot Ezb For Robot Head Project

My course has primarily focused on robotics projects using the EZ-B controller and a camera for real-time interfacing. With recent developments, I am planning to create an additional video that incorporates Synthiam's support for other types of controllers. Although I've successfully flashed an alternative controller, it lacked compatibility with camera integration and Wi-Fi capabilities. The absence of an onboard computer limits the use of a USB camera, posing a significant challenge.

This dependency on specific components like the EZ-B, IO Tiny, and cameras can be problematic. For my course project, Mecha Morphix, which involves controlling five servos, the Arduino Mega seems excessive. I am in search of a suitable controller, compatible with Synthiam ARC, that includes both Wi-Fi and camera support to effectively replace the EZ-B.

I noticed that the ESP32 with a camera is listed among the supported controllers for ARC. Has anyone experimented with using the ESP32 in conjunction with a camera for such applications? Any insights or experiences would be appreciated.

Haha I’ll take the beers thanks.

did you try v13? Did it make a difference?

Ran out of time last night. Will test today after I drop off my kids to school.

No rush on this at all. Just getting around to trying ver 13.

  • ESP32-Cam (ver 13)
  • ARC ver 2.19.01
  • After I connect to the ESP32, I can move a servo

  • After I connect camera frame is frozen and camera drops with error message in the video. (new)

  • The connection to the ESP 32 soon after drops as well. (new)

ARC error message is a s follows:

Connected TCP Comm Error: Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host. Sent: 4 6 9 0 35 48 80 49 52 57 52 13 10 Bytes Expected: 0 Received (0 bytes): Disconnected
