Teaching an Arduino UNO R4-powered robot to navigate obstacles autonomously
The rapid rise of edge AI capabilities on embedded targets has proven that relatively low-resource microcontrollers are capable of some incredible things. And following the recent release of the Arduino UNO R4 with its Renesas RA4M1 processor, the ceiling has gotten even higher as YouTuber Nikodem Bartnik has demonstrated with his lidar-equipped mobile robot.

Machine Learning Robot Runs Arduino Uno
When we think about machine learning, our minds often jump to datacenters full of sweating, overheating GPUs. However, lighter-weight hardware can also be used to these ends, as demonstrated by [Nikodem Bartnik] and his latest robot.

Dual Raspberry Pi Pico W Power RC Car and Controller
Paulsb went on to explain some of the design choices in the build. Most notably, the controller uses a Pico W as the main board but he also had to an an ADS1115 ADC board as the Pico W only has three analog channels. The ADS1115 adds an additional four ADC channels to the Pico W controller.

Librem 5 @ $999 or $899 when Bundled with AweSIM Cellular Service
Due primarily to the overwhelming demand for the Librem 5 we were able to lower our component costs in recent purchasing, this was certainly welcome news after the higher pricing seen during 2021, 2022, and into 2023. With our latest fabrication run we are now able to pass that savings onto new customers.
After reaching shipping parity for the Librem 5 and shipping all new orders within our standard 10 day fulfillment window, we are proud to be able to lower the initial purchasing price for new Librem 5 to $999 (a $300 savings from peak pricing).
Equivalent to getting the first month free of Librem AweSIM cellular service. Librem AweSIM—like VPN for cellular—ensures you are protecting your personal identifying information and financial details from all the carriers. You can now bundle and save, where you can buy the Librem 5 at $899 (a $400 savings) coupled with Librem AweSIM (a $99/mo unlimited voice and data service).

Meet Joel Gomes: Fire, jet engine, 3D printing, and Nikola Tesla fan
Anyway, he developed all of that. Somehow, Marconi got the idea of reading his patents. And he realised, if he put like seven patents together, you could build a radio. He kind of pulled the rug out from under Tesla. He got the radio first, and once Tesla’s sponsor knew that the radio was out there, he was like, “Oh, I don’t need you any more, I’m not giving you any more money.”
