Overview and Introduction:

Author: Jim Burnham - TopClown@STEAMClown.org. License: Distributed as Open Source. 

Prerequisites:

• No explicit prerequisite course work or coding knowledge is required, but students are expected to have a good understanding of basic computer principles.

Caution & Safety  Considerations:

Primer:  "Aaron, I can imagine no way in which this thing could be considered anywhere remotely close to safe. All I know is I spent six hours in there and I'm still alive... You still want to do it?"

• As with any activity, please make sure you are using appropriate safety equipment.   If you are coding, writing, reading, or working a lab, make sure you stand up and stretch every hour or so,  Please consider any safety issues connecting to a Raspberry Pi, Arduino, computers and other electronic equipment.

Essential Questions:

• What information can you transwmit & recenve on a Rover or Robot?

Safety Stuff Rovers Could/Should Have

All these Features / Sensors / Options Are Potentually A Robot Club Project

Safety Topics 

Emergency-Stop

• Layered E-stop - Fail-safe NC latching relay + motor-driver enable pin

• RF dead-man switch - Untethered outdoor operation (walk along pull cord), Remote "Kill /Deadperson" button built into controllers

Rover Status - Safety

• Physical bumpers or contact switches Last-resort collision detection that works when the cameras don't

• Stack light + buzzer Shows armed / autonomous / fault states to people nearby

Addition Safety Topics:

• Standards awareness - ANSI/RIA R15.08, ISO 3691-4, ISO 13849-1, UL 3100

The biggest gaps for the big outdoor rover, in priority order:

1. A link-loss failsafe. The rover should stop automatically if the control link drops. Design a layered E-stop and a dead-man switch, with a watchdog on the radio link is a separate protection. Rover stops automatically if the control or telemetry link drops for more than about 0.5–1 s. Separate from the dead-man switch.

2. Health monitoring. Track battery voltage and current, current on each motor, and temperatures on the hub motors and controllers. Hub motors working through grass get hot, and current spikes are your best stall and stuck-in-mud indicator.

3. Sensors that work in sunlight. Ultrasonic and cheap IR ToF sensors that work indoors struggle outdoors in sunlight and grass. Plan on an outdoor-rated LiDAR plus downward-facing "cliff" sensors to catch ditches and holes.

4. Sensor fusion. Combine RTK GPS, the IMU, wheel and steering encoders and optical flow in an EKF (ROS 2 robot_localization) instead of trusting any single source.

5. Tilt cutoff, geofence and stack light. These are cheap and important once the rover is heavy and moving fast near people. Tilt / rollover cutoff from the IMU - Stop motors past a safe pitch or roll angle

• 🚀 Formative Quiz - 🔎 Review

• 🚀 Quiz -🔀 Mastery Path

• 🚀 Summative Quiz -✔️ Skills Mastery Check

Quiz - verify that they are all listed as a "Formative", "Mastery Path", or "Summative" 

• 🚀 Formative Quiz - These are quizzes that the students can take a few times. I have them either set for unlimited times, or 3-5 times, where the final score is their average. The idea is that these Formative Quizzes are designed for students to learn and master a skill.  while I want them to ger 100%, and when it's set to unlimited tries, the student should get 100% eventually.  When the quiz is set to 3-5 tries with an average, then they should be prepared and should take the quiz seriously. I set the quiz to not show the right answer, but I do let them see their wrong answer.  I also put the explanation of the right and wrong answer in the right and wrong answer prompt for each question.  That way they can see why they got the answer wrong and learn from that experience.

• 🚀 Quiz -🔀 Mastery Path - These Mastery path quizzes are to be presented after the student has had a chance to do some labs and some Formative quizzes.   The goal is to let students have 2 chances to take this quiz, and take the average of the 2 attempts.  Based on the average, they will be presented with a Canvas Mastery Path, where they will have an option for take additional quiz and assignments to help with remediation.  This will get them ready to take the Summative Quizzes.

• 🚀 Summative Quiz -✔️ Skills Mastery Check - These Mastery path quizzes are to be presented after the student has had a chance to do some labs and some Formative quizzes.   The goal is to let students have 2 chances to take this quiz, and take the average of the 2 attempts. That will be their final module/subject topic grade.
