Building a Raspberry Pi Robot with Dot NET 8, Blazor and SignalR - Slides Only.pptx

In this session delivered at Leeds IoT, I talk about how you can control a 3D printed Robot Arm with a Raspberry Pi, .NET 8, Blazor and SignalR.

I also show how you can use a Unity app on an Meta Quest 3 to control the arm VR too.
