Drive to Target EV

Hello! This is my attempt at making a accurate drive-to-target vehicle! The goal is to make the car accelerate and steer accurately to reach set waypoints and destinations within 1 cm accuracy over 10 meters.

Total total time spent: 20.5h

1 | June 15 | Project Setup!

• Had the idea for a while, but finally started organizing my thoughts! I laid out goals and checkpoints for this project.
• Started researching part sourcing(motors, wheels, axles)
• Figured out how to use Github+GitKraken
• Opened PR to add to submissions.
• Figured out constraints: 12v by 8AA Batteries only, must be under 80cm length and 30cm width, must be able to reach 10m in <5 seconds
• Scouted two popular compatible motor sizes(25&37mm)
• New dilemma: Separate encoder for accuracy? (edit - yes)

Starting CAD hopefully!

Total time spent: 4h

2 | June 16 | CAD work

• finalized BOM
• Finalized design plans(in my head unfortunately)
• Started -> Finished! Axle and motor(front) assembly
• Almost finished with rear assembly
• Started code, skipping PCB because waste of money + this project will have multiple iterations

Total time spent: 5.5h

3 | June 17 | CAD + Code

• Finished back assembly!
• Realized I have no materials so actually finalized BOM
• Learned PIO! (used to use Arduino IDE)
• Learned some kinematics but still confused
• got cooked byAlmost finished code prototype(copilot help is useful but annoying at the same time 😭)
  • i have no coding skills i hate this...

Total time spent: 6h

4 | June 18 | CAD + Code + Electrical

• Finished code!
• FINISHED CAD????? (making 23 studios for this was not what i expected)
  • Don't know why any of my cad files are not named - I did but too lazy to fix here
• Decided to mess with onshape drawings
• Starting on electrical now! Ok so i finished?
• Final Review -> BOM uploaded, README finished

Total time spent: 5h
