Gearbox Work Part 1
Did alot of work on the gearbox but eventually ended up deleting 2 gears, realised that the shifting mechansim was just based on two little inserts that lock under the gear, silly me, under high speeds that will crack almost instantly, so i will implement the shifting tecnique they use in cars with teeth locking into other teeth

Lovely stuff!

Devlog #2

I (Hopefully) learnt how to use markdown

What I did today 😸:

•Today I finished off the cad designs by adding 3mm holes for where mounts and etc go for M3 screws (3mm)

•Now although this may seem like simple work i can assure you it was not, as i had to expertly place the holes in strategic places so it doesnt crack easily, So basically most time was spent procrastinating and evaporating as its currently like 28°c in the UK.

•Also kinda found suspension links shocks motor battery mounts screws receiver servo axles. But that will be submitted on the Github BOM later!!

-What’s next:

•Drivetrain Design (Gearbox etc)
•Add parts to the BOM, and properly journal (is this journaling???)
•Final simulation
•ASSEMBLY!!

You can find the laser cutting files if you wanna see them at: Project-Mud-Striker Github

Devlog #1
What i did today 😸
today i did the basic cad designs of the side rails of the crawler (if you are not sure what a crawler is its basically a rc offroad expedition-y vehicle that has high toque and power to climb rocks and obstancles, basically a scale down remote controlled truck)

I realised after a while that the 12mm i had the chassis vertical width or whatever was far too small, and at high speed bumps, the aluminium/stainless steel will crack over time, decreasing the longetivity, so thats why i increased it to 20-25 mmon certain points, and even higher on joints and bends because thats whel most stress will be exerted. see below in red:

Whats next??

-Adding cutouts for links and shocks

-Designing drivetrain

-Choosing electronics: Battery motor reciever transmitter servos etc

-Assembling maybe!?!?!

Okay so my back doesnt hurt today

I worked on the wing and installed the ESCs, tested the motors using pixhawk and they both respond properly

I do have a little concern as the ESCs are getting slightly warm, i did remove the rubber like i did on my older ESC, that doesnt seem to make it any better, the ready to sky esc i used earlier didnt have this heating problem, idk whats going on, i hope it js doesnt end bad

The good news is that i installed servos and their linkages to the alerons, i will have a flaperon configuration for nice low effort flaps.

Today the aircrafts weight is 560gs without the battery, so im assuming this will be around 750-800 grams with the 1500 3s lipo

Istg i hate soldering these thick wires, its js so tedious

Nexi Devlog — 13/06/2026

Progress Update

• Began moving from concept into actual schematic and system design
• Focused on turning the idea of Nexi into something physically buildable

What’s Been Done

• Defined Nexi as a rover-style companion bot
• Confirmed use of a 4 wheel independent drive system
• Each wheel will have its own motor for precise control
• Started building and wiring internal modules within the schematic
• Established basic signal flow between components

Design Decisions

• Chose independent wheel drive instead of traditional steering

• This allows:

  • Turning on the spot
  • Better movement in tight spaces
  • Easier recovery from difficult positions

• This approach makes Nexi more flexible for exploration

Current State

• Core modules are now placed and wired in the schematic
• Overall system structure is beginning to take shape
• Ready to move into control and logic implementation

Next Steps

• Add control signals such as clock and enable
• Implement output handling and selection logic
• Begin integrating sensors for environmental scanning
• Start designing the display system for Nexi’s face
• Test basic movement logic

Notes

• The project is becoming more complex than originally planned, but this is intentional
• Nexi is designed to be both functional and expressive, not just a simple robot
• Long term goals still include interaction with the environment and basic object manipulation
