Machine learning on Microcontroller
A 0.23 TOPs solution like you showed will have an inference latency of multiple hundreds of ms (a couple of frames per second.) This might be acceptable for a slow-moving RC car. Something faster will want higher throughput / lower latency.

There are AI compute stick accelerator solutions that can work with a microcontroller over USB. Well-known ones include Google Coral, Intel / Movidius Myriad X. Less well known is the Gyrfalcon 5801, which is the same chip as in the new LG Q70 phone.

These solutions will have throughputs in the 10 - 50 fps range, enough to cover  single camera with reasonably low latency.

Might as well add this one too: Solidrun offers a System-on-Module with an i.MX8 and 16.8 TOPs AI coprocessor. This will be able to handle multiple cameras at low latency. Frame rates in the multiple hundreds of FPS. More here: https://www.solid-run.com/nxp-family/imx8m-mini-som/
