  • Building a Distribution: Openharmony and Openmandriva
    Two different approaches to building a distribution: OpenHarmony and OpenMandriva Bernhard "bero" Rosenkränzer <[email protected]> FOSDEM 2021 -- February 6, 2021 1 MY CONTACT: [email protected], [email protected] Way more important than that, he also feeds LINKEDIN: dogs. https://www.linkedin.com/in/berolinux/ Bernhard "bero" Rosenkränzer I don't usually do "About Me", but since it may be relevant to the topic: Principal Technologist at Open Source Technology Center since November 2020 President of the OpenMandriva Association, Contributor since 2012 - also a contributor to Mandrake back in 1998/1999 2 What is OpenHarmony? ● More than an operating system: Can use multiple different kernels (Linux, Zephyr, ...) ● Key goal: autonomous, cooperative devices -- multiple devices form a distributed virtual bus and can share resources ● Initial target devices: Avenger 96 (32-bit ARMv7 Cortex-A7+-M4), Nitrogen 96 (Cortex-M4) ● Built with OpenEmbedded/Yocto - one command builds the entire OS ● Fully open, developed as an Open Source project instead of an inhouse product from the start. ● For more information, visit Stefan Schmidt's talk in the Embedded devroom, 17.30 and/or talk to us at the Huawei OSTC stand. 3 What is OpenMandriva? ● A more traditional Linux distribution - controlled by the community, continuing where Mandriva left off after the company behind it went out of business in 2012. Its roots go back to the first Mandrake Linux release in 1998. ● Originally targeting only x86 PCs - Support for additional architectures (aarch64, armv7hnl, RISC-V) added later ● Repositiories contain 17618 packages, built and updated individually, assembled into an installable product with omdv-build-iso or os-image-builder.

DeepPicar is a small scale requires a high computing capacity as well as the means to replication of a real self-driving car called DAVE-2 by NVIDIA. guaranteeing the timings. On the other hand, the computing DAVE-2 uses a deep convolutional neural network (CNN), which takes images from a front-facing camera as input and produces hardware platform must also satisfy cost, size, weight, and car steering angles as output. DeepPicar uses the same net- power constraints, which require a highly efficient computing work architecture—9 layers, 27 million connections and 250K platform. These two conflicting requirements complicate the parameters—and can drive itself in real-time using a web camera platform selection process as observed in [25]. and a Raspberry Pi 3 quad-core platform. Using DeepPicar, we To understand what kind of computing hardware is needed analyze the Pi 3’s computing capabilities to support end-to-end deep learning based real-time control of autonomous vehicles. for AI workloads, we need a testbed and realistic workloads. We also systematically compare other contemporary embedded While using a real car-based testbed would be most ideal, it computing platforms using the DeepPicar’s CNN-based real-time is not only highly expensive, but also poses serious safety control workload.

  • End-To-End Learning for Autonomous Driving Robots
    End-to-End Learning for Autonomous Driving Robots Anthony Ryan 21713293 Supervisor: Professor Thomas Bräunl GENG5511/GENG5512 Engineering Research Project Submitted: 25th May 2020 Word Count: 8078 Faculty of Engineering and Mathematical Sciences School of Electrical, Electronic and Computer Engineering 1 Abstract This thesis presents the development of a high-speed, low cost, end-to-end deep learning based autonomous robot driving system called ModelCar-2. This project builds on a previous project undertaken at the University of Western Australia called ModelCar, where a robotics driving system was first developed with a single LIDAR scanner as its only sensory input as a baseline for future research into autonomous vehicle capabilities with lower cost sensors. ModelCar-2 is comprised of a Traxxas Stampede RC Car, Wide-Angle Camera, Raspberry Pi 4 running UWA’s RoBIOS software and a Hokuyo URG-04LX LIDAR Scanner. ModelCar-2 aims to demonstrate how the cost of producing autonomous driving robots can be reduced by replacing expensive sensors such as LIDAR with digital cameras and combining them with end-to-end deep learning methods and Convolutional Neural Networks to achieve the same level of autonomy and performance. ModelCar-2 is a small-scale application of PilotNet, developed by NVIDIA and used in the DAVE-2 system. ModelCar-2 uses TensorFlow and Keras to recreate the same neural network architecture as PilotNet which features 9 layers, 27,000,000 connections and 252,230 parameters. The Convolutional Neural Network was trained to map the raw pixels from images taken with a single inexpensive front-facing camera to predict the speed and steering angle commands to control the servo and drive the robot.

Welcome, Guest Log in Register Activity Search Translate Content Participate Learn Discuss Build Find Products Store Raspberry Pi Raspberry Pi 4 Laptop Posted by stevesmythe in Raspberry Pi on Nov 23, 2019 4:17:58 PM [Updated 03 January 2020 - see addendum at bottom of the page] I was lucky enough to win one of the 20 Raspberry Pi 4s in the element14 "Happy 10th Birthday!" giveaway. My suggestion was to use the Pi 4 to run Pi-Hole on my network to block unwanted adverts that slow down my browsing (and not just me - everybody in the household). This worked really well and I'll blog about it shortly. I've been reading reports of people using the Pi 4 as a low-cost desktop computer and tried that out myself by adding a screen and one of the new Raspberry Pi Keyboard/ Mouse combos. Not forgetting an official Raspberry Pi 4 power supply. I was pleasantly surprised at how usable it was. However, I'm running low on desk space to hold another monitor/keyboard so I haven't really made much use of it. I recently noticed that element14's sister site CPC Farnell in the UK was selling off the original Pi-Top (Raspberry Pi laptop kit) for £80 plus VAT. It originally cost around £200. For £80 you get an (almost) empty laptop shell, with a large capacity (43-watt-hour) Li-ion battery, keyboard (with trackpad), a 1366x768 resolution TFT LCD screen and 3A power supply.

  • Using Pareto Optimum to Choose Module's Computing
    29TH DAAAM INTERNATIONAL SYMPOSIUM ON INTELLIGENT MANUFACTURING AND AUTOMATION DOI: 10.2507/29th.daaam.proceedings.081 USING PARETO OPTIMUM TO CHOOSE MODULE’S COMPUTING PLATFORMS OF MOBILE ROBOT WITH MODULAR ARCHITECTURE Victor Andreev, Valerii Kim & Pavel Pletenev This Publication has to be referred as: Andreev, V[iktor]; Kim, V[alerii] & Pletenev, P[avel] (2018). Using Pareto Optimum to Choose Module’s Computing Platforms of Mobile Robot with Modular Architecture, Proceedings of the 29th DAAAM International Symposium, pp.0559-0565, B. Katalinic (Ed.), Published by DAAAM International, ISBN 978-3-902734-20-4, ISSN 1726-9679, Vienna, Austria DOI: 10.2507/29th.daaam.proceedings.081 Abstract This paper tries to address a sufficiently complex task – choice of module’s computing platform for implementation of information-measuring and control system (IMCS) of full-functional modules of mobile robot with modular architecture. The full functionality of a mechatronic device is the ability to perform its goal function using only its own facilities for executing instructions from an external control system. This condition sets for robot’s IMCS some specific requirements on selection of corresponding computational platform, which one could separate into objective, subjective and computative-objective criteria. This paper proposes use of discrete optimization with Pareto-optimum to select viable alternatives from computing platforms which can be both off-the-shelf and perspective products. One of the main criteria – such embedded computing platforms must have suitable computational power, low weight and sizes. The paper provides descriptions of different computing platforms, as well as the rationale for main quality criteria of them. An example of Pareto optimization for a specific IMCS solution for some types of mobile robot modules with modular architecture is provided.

  • Developing an Autonomous Driving Model Based on Raspberry Pi
    Developing an Autonomous Driving Model Based on Raspberry Pi Yuanqing Suo, Song Chen*, Mao Zheng Department of Computer Science *Department of Mathematics and Statistics University of Wisconsin-La Crosse La Crosse WI, 54601 [email protected] Abstract In this project, we train a convolutional neural network (CNN) based on the VGG16 using the lane image frames which are obtained from a front-facing camera mounted on a robotic car. We then use our trained model to drive the car in a predefined environment. The model will give the steering commands, such as forward, left-turn and right-turn, to make the car drive in the lane. The dataset we used to train and test the model contains more than 120 minutes of driving data. In a pre-trained real environment, the model can operate the robotic car to continuously drive in the lane. We trained the self-driving model by giving raw pixels of the lane image frame. The model will predict the next steering command based on the current frame state. This end-to-end approach significantly relies on the quality of the training dataset. To collect the training dataset, we chose a pi camera version one module with 5 megapixels resolution instead of a USB 2.0 8 megapixels (MP) resolution web camera. Although the webcam has a higher number of megapixels, it has a low frame rate and no GPU encoding. On the other hand, the pi camera has GPU encoding, and 5 megapixels resolution which produces decent quality image frames. In addition, the pi camera has a wide field of view in images.
