Week 2 Progress Report
Overview
Printed parts to be machined (from steel material)
Parts arrived, with a rudimentary fit using the parts completed
Researching steering column/EPAS system
Accomplishments from previous week
Emergency Brake
3d printed parts for dry fit
Developed solution for installing additional frame (for lever pivot)
Pressure Sensor
Attached brake system to kart
EPAS system
Caught up on CAN and OpenPilot steering system
Attempted to initialize EPAS via spoofing signals
Goals for next week
Finish brake pressure sensor (Nicholas)
Assemble actual emergency brake (Alex)
Verify specs and find tolerances for springs, magnet
Continue cooperating with EPAS team (Angel)
Implement OpenPilot system to control EPS
Install frame, pending approval. Assemble steering wheel mount. (Sebastian)
Order additional parts (brake cable, bearings)
Sponsor Comments
In-person (04/04)
Basic PID algorithm for pressure sensor
Work with other members of Triton AI
Work with others on hacking EPAS system
Can read torque but cannot control it
Deliverables
Brake pressure sensor
Characterize steering column/EPAS system
Develop steering wheel frame
Help with EPAS hacking and learn
Have a comma ai 3, with open pilot
At the moment need to know what openpilot uses to control postion/control of car
Use own ECU from EPS to control EPS, via position control (degress) and direction
2 wires from epas connect to CAN: what materials do i need to buy? Is comai3 necessary? What commands can i use to talk to the epas and control
Instructor Comments
Bronze bearings
Lasercut lever if possible
Check tolerances for springs and magnets
Ensure car computer works with EPAS system, OS can change
Attempt to ask engineers themselves
