Minutes

• @Thomas Watteyne

  • working on SCuM programmer programmer

    • clean software project

    • repo:

    • release: https://pypi.org/project/scumprogrammer/

    • how to use?

      • install Python 3

      • pip install scumprogrammer

      • scumprogrammer

• @Fil Maksimovic submitted his paper on lighthouse localization to https://www.icra2022.org/

• @Razanne Abu-Aisheh

  • Atlas works with pister-hack

  • Added Concurrent transmisison and dynamic relay placement algorithm

  • Algorithm works well but is very slow. Am working on re-architecting and optimising to make it faster.

• @Felipe Campos @José Astorga Tobar

  • All DotBot Python package code consolidated in GitHub - DotBots/PyDotBot: A complete environment for controlling and tracking DotBots

  • Implemented HTTP Orchestrator (single gateway) to control DotBot movement remotely

    • Goal: As long as Xbox controller, iPhone, or some centralized controller (e.g. Atlas) conforms to API specification, they can control a single or a swarm of DotBots via the Internet or localhost

    • MQTT skeleton in place to allow for several Gateways through the public HiveMQ broker

    • Focusing on updating Gateway and DotBot firmware

      • Passing calibration parameters & computing positions on-board DotBot (1. angle 2. x/y given 1 ceiling LH & height 3. x/y given 2 LH & homography + scale)

• @Fil Maksimovic @Alfonso Cortés

  • Starting to work on getting a RISC-V core running on a TinyFPGA

    • Goal: flexible accelerators and peripherals

• @Said Alvarado-Marin

  • Worked with Fil on submitting the light house localization paper.

    • Made some augmented reality plots in Blender for the paper.

  • Debugging Lighthouse glitch in DotBot.

    • Confirmed the existence of a software bug in the DotBot firmware. Bluetooth stops transmitting randomly.

• @Mina Rady

  • Sending out PhD Manuscript today “Agile Multi-PHY Wireless Networking”.

  • Next: building a demo for a 100 km Mesh.

• @Alex Moreno

  • boards

    • 2 Sulu variants: with regulator or LDO

    • panelized fabrication

    • $350: pannel of 48 motes, expect 5 not to work, ordered 3 panels to have 129 boards

    • ordered a stencil as well

    • order placed

  • die testing

    • looking for what is going on

    • we shoud work on nRF+SCuM test programmer

    • 9 pins

  • will be discussing with @Fil Maksimovic about VDDD

• @David Burnett

  • Has the program counter been inspected to see which instruction a vddtap chip stalls on? We should be able to use the digital scanchain to grab the program counter without the CPU operating.
