Raw Blame History

Hardware

  • Make the prototype hover

  • Build Mock-up body to not destroy it while testing

  • Servo calibration

  • Test without propellers

  • Add propellers

  • Control system check by flying while holding

  • Look at logs, do they contain all variables that should be monitored?

  • Do we need to customize the log?

  • Does the control system input look healthy?

  • Make redundant esc's

  • Proof of work:

  • Using 2 vescs and a custom application show that 2 vescs can control a single motor

  • Where does the error signal come from? How can we generate it / monitor the health of the esc?

  • Version 2 of PDB

  • Make 5V rail and 7.4V rail redundant!

  • Formfactor & Weight!

  • Carrierboard No. 2

  • Coral vs Qualcomm --> See performance etc. with Iñigo

  • If Coral

  • Decide on cameras and make custom connector

  • Sensors & Actuation

  • GPS: Decide which GPS modules & antennas

  • --> test performance between ZED & NEO (with and without correction services)

  • Test antenna performance

  • IoT: Is SARA chip enough? --> make or use API to integrate SARA into our ROS system.

  • Define purpose precisely of SARA Chip. What needs to be communicated? What packages exchanged?

  • Airspeed sensor

  • Test windspeed sensor when it arrives

  • How important is it? Do we manage without?

  • Research Stall and stall detection (can It be detected without windspeed sensor?)

  • What is the lifetime of the servos? Can we find better servos?

  • What servos does nasa use on their Ingenuity copter? --> Maxon

  • Send email to maxon

  • Are there servos that run on 6s? --> would greatly simplify pdb.

Software

  • Sensors & Actuation

  • Attach GPS Module to PX4

  • Does it work?

  • How do we need to tweak it?

  • Communication High level

  • What packages are being sent between corals and px4?

  • What data needs to be shared? (make a list! GPS, etc.)

  • Redundancy

  • How do we run 2 px4s in parallel?

  • Make high-level node graph of our architecture

  • What nodes work fine, what nodes need to be implemented?

  • Make requirements list of PX4 part. Is it suited as it is or does it need to be modified?

  • Low-level Communication

  • UAVCAN vs other protocols

  • Qualcomm vs Coral. 

Modelling & Control System

  • Make the prototype hover like a heli

  • Model the drone with matlab and come up with strategy for control system
