⚡️ Quick Tips and Facts About Robot Hardware Documentation

  • Document first, solder later. We’ve seen too many teams fry a roboRIO because they mixed up the red and black wires. A single page of robot hardware documentation saved our bacon at 2 a.m. in the pits—twice.
  • 80 % of field failures trace back to missing or outdated docs, not bad luck. (Source: NI FRC white-paper)
  • One-liner rule: if a freshman can’t find the pin-out in under 60 s, your docs need a rewrite.
  • Hot tip: store PDFs on the robot in a labelled USB-C thumb-drive velcroed inside the electronics tray—inspectors love it, and you’ll never hunt for the CTRE PDP manual again.
  • LSI keywords you’ll see a lot today: robot wiring diagrams, FRC electronics specs, motor controller datasheets, pneumatics schematic PDF, roboRIO pin-out, power-distribution-hub telemetry, servo-hub wiring guide, robot battery spec sheet, circuit-breaker sizing chart, robot hardware BOM template.

🤖 The Evolution and Importance of Robot Hardware Documentation

Video: The Ultimate Guide to using Motors in Robotics (including ROS, Raspberry Pi).

Once upon a time (2010), “documentation” meant a napkin sketch of the Spike H-Bridge and a prayer. Fast-forward to 2024: robots run 200 A peak current, push 30 MJ of energy per match, and pack more sensors than a self-driving tractor. Without hyper-detailed robot hardware documentation, you’re flying a 120-lb drone blindfolded.

We still keep the napkin—laminated—for nostalgia.

Why Docs Matter More Than Code

  • Hardware doesn’t throw exceptions—it releases magic smoke.
  • Judges at competition score engineering portfolios; glossy photos won’t save you if the inspector asks for the REV PDH current-limiting procedure and you blink.
  • Future team members inherit your mess. Be kind.

Milestones That Forced Our Hand

Year Game-Changer Doc We Had to Produce
2015 FIRST allows 6-motor drives Full 40 A breaker table per motor
2019 Brushless NEO arrives NEO encoder phasing diagram

Below we dissect every FRC-legal (and many hobby) power pieces you’ll document. Grab coffee; this is the IKEA of robotics.

1. Control Systems and Their Documentation Essentials

1.1 NI roboRIO — the Brain

  • Specs you MUST write down: 3.3 V & 5 V rail max current (1 A & 2 A), DIO voltage threshold (0.8 V / 2 V), USB back-feed protection (yes, it has one).
  • Pro-tip: export the SysDef file; it auto-generates a wiring table you can paste into your docs.
  • Where to buy & docs:
    👉 Shop NI roboRIO on: Amazon | NI Official

1.2 Alternatives for Off-Season

  • Raspberry Pi 4 + PICAN-M: great for autonomous robots prototypes, but you’ll need to document 5 V ➜ 3.3 V level-shifters.
  • HEBI Compute Module: modular, but pricey; docs are gorgeous (HEBI docs).

2. Power Distribution Units: Types and Documentation Best Practices

Feature CTRE PDP (Classic) CTRE PDP 2.0 REV PDH
Channels 16 (8Ă—40 A, 8Ă—30 A) 24Ă—40 A 20Ă—40 A + 3Ă—15 A
Breaker Style Snap-Action 30/40 A ATO automotive WAGO tool-less
CAN Telemetry ✅ current, temp ✅ plus joules counter ✅ plus sticky faults
Weight 0.29 lb 0.33 lb 0.27 lb
Quick-Connect? ❌ ✅ ATO blades ✅ Lever-clamp

Document each channel’s load in a Google-Sheet, then PDF it—inspectors adore printable labels.

3. Circuit Protection Devices: Circuit Breakers and Relays Explained

3.1 Main Breaker — 120 A Anderson-SB50

  • Datasheet gold: trip-time curve. We tape a miniature inside the battery bag.
  • Gotcha: cold weather increases trip-time; document derate for Detroit-regionals (ask us how we know).

3.2 Branch Breakers

  • Snap-Action MX5 vs ATO automotive vs REV mini-blade.
  • MX5 advantage: vibration-proof for battle-bots.
  • ATO advantage: cheap at any auto-parts store at 3 a.m. when you blow one Saturday morning.

3.3 Relics: Spike H-Bridge

  • Discontinued 2015, yet every lab has one. We use it to power LED strips off a 20 A ATO because it’s fun to say “Spike relay” with a straight face.

4. Batteries and Power Management: Documenting Energy Sources

Chemistry SLA (FRC) LiFePO4 (Hobby) Li-ion 6T (Mil-Spec)
Nominal 12 V 18 Ah 12.8 V 10 Ah 14.4 V 6.8 Ah
Peak Draw 300 A 200 A 400 A
Weight 12.5 lb 3.3 lb 4.1 lb
Docs Must Include IR curve, CCA, shelf-life BMS pin-out NATO connector pin

Pro-tip: log every battery’s internal-resistance on arrival; we stick a QR-code that links to a Google-Sheet—inspectors scan, nod, smile.

5. Pneumatics Control Modules: Hardware and Documentation Insights

5.1 CTRE PCM vs REV Pneumatic Hub

  • PCM needs external pressure switch; REV Hub has two onboard sensors—document which port is which (they’re silk-screened in 4-pt font, good luck).
  • Both allow compressor auto-control when robot is enabled; capture the logic flow in a diagram so software doesn’t accidentally vent 120 psi across the driver station.

6. Motor Controllers and Servo Systems: Hardware Specs and Docs

6.1 Brushless vs Brushed — the eternal war

  • Brushless (NEO, Falcon) needs phase-order diagram in docs; swap any two wires and the motor runs backwards—ask any rookie.
  • TalonFX integrates encoder; document counts-per-rev (2048) and velocity-filter coefficient or your PID will sing the song of its people.

6.2 Servo Power Module

  • 90 W at 6 V means you can run 18 high-torque servos simultaneously—if your docs list the stall-current of each servo. We didn’t, and browned-out the roboRIO—twice.

7. Sensors and Cameras: Documenting Vision and Feedback Hardware

7.1 Microsoft LifeCam HD-3000

  • 720 p @30 fps via USB 2.0; document auto-exposure off in your vision pipeline or the ring-light will strobe like a disco.
  • Lens FoV is 68° diagonal; we print a paper protractor for quick calibration.

7.2 HEBI X-Series Actuator

  • Integrated 3-axis gyro & temp sensor; docs include ROS URDF snippet—copy-paste into your robot model and watch RViz smile.

📚 Best Practices for Creating and Maintaining Robot Hardware Documentation

Video: How to build a robot in one minute.

  1. Single Source of Truth
    Host everything in a Git repo (Markdown + CAD + PDF). Freshmen clone once; veterans edit & push.

  2. Templates We Swear By

    • Wiring Sheet: channel, device, breaker-size, wire-gauge, colour, purpose.
    • Checkout Sheet: inspector signature, date, battery IR, RSL flash-test, pneumatics leak-down (psi/min).

  3. Version Like Netflix
    Tag releases: 2024-robot-v1.3. When you strip wires at 1 a.m., you’ll know which PDF matches the bot in front of you.

  4. Visuals > Paragraphs
    Embed 3-D QR codes linking to OnShape or STEP files. Judges scan, spin the model, instant nerd-cred.

  5. Automate Where Possible
    Use GitHub Actions to compile LaTeX schematics into PDF on every push—yes, we’re that nerdy.

Problem: “We can’t find the right breaker size for the Falcon.”
Fix: Our breaker-sizing flowchart (PDF linked in repo) uses stall-current × 1.25 rule—print & laminate.

Problem: “RSL solid instead of flashing.”
Fix: 90 % of the time someone tied the RSL to the 5 V rail instead of the RSL port—document rail limits in bold red.

Problem: “Compressor randomly shuts off.”
Fix: PCM pressure-switch hysteresis is 5 psi; if your docs don’t list it, you’ll chase ghosts.

🌐 Integrating Robot Hardware Documentation with Software and Firmware Docs

Video: Five Things You Need Before Starting With ROS | Getting Ready to Build Robots with ROS #1.

  • Hardware-in-the-loop: we paste hyperlinks to API entries (Java, C++, Python) right next to the schematic net-label.
  • Parameter sync: store PID gains in a YAML inside the repo; both the TalonFX firmware and the Java constants pull from it—no magic numbers.
  • Continuous Integration: every push triggers unit-tests on the roboRIO emulator; if the current-draw in sim exceeds the doc limit, build fails—robotic justice.
