Unplugged Cyber-STEM Pack 3: Rover Navigation (Grades 4–8)

Introduce differential drive kinematics, wheel velocity turning calculations, ultrasonic sonar triangulation vectors, wall-following algorithmic control loops, and real-world planetary robotics with Unplugged Robotics & Cyber-STEM Unit 3: Autonomous Rover Navigation Algorithms! Designed for grades 4 through 8, this 9-page printable resource is 100% unplugged (requiring zero screens, block coding software, or digital hardware) and engineered for a seamless 60- to 75-minute rotation lab, workshop, or whole-class STEM activity using low-cost supplies like grid paper, rulers, protractors, and calculators.

What Is Included in This 9-Page Pack?

• Page 1: Teacher Setup & Master Guide

  Features a comprehensive materials list, desk layout station map, coordinate grid setup steps, and rotation pacing strategies.

• Page 2: Student Answer Sheet (1-Page Master Handout)

  A single, organized recording worksheet designed for students to clip to a clipboard and carry through every station for smooth accountability.

• Page 3: Station 1 Sign — Unplugged Grid Navigation Lab

  Interactive navigation station where students plot directional step commands on a Cartesian grid to steer a rover from Start (0,0) to Goal (6,6) around physical hazards.

• Page 4: Station 2 Sign — Differential Drive & Velocity Lab

  Applied math and physics lab where students evaluate left vs. right wheel speed differential formulas (V_L vs. V_R) to calculate turning radius curves and pulse timings.

• Page 5: Station 3 Sign — Sonar Triangulation Schematic

  Technical blueprinting station where students map 2D ultrasonic echo reflection rays, identifying sensor blind spots and surface angle signal distortions.

• Page 6: Station 4 Sign — Autonomous Wall-Following Algorithm

  Unplugged computer science station where students analyze closed-loop conditional flowcharts (If/Then loops) to calculate real-time motor course corrections along a wall perimeter.

• Page 7: Station 5 Sign — Real-World Case Study

  Informational reading passage on NASA's Mars Perseverance Rover AutoNav System, examining deep-space signal latency, 3D terrain mapping, and autonomous obstacle avoidance.

• Page 8: Detailed Teacher Answer Key

  Provides worked coordinate paths, wheel velocity math answers, sonar diagram standards, algorithm decision keys, and case study responses in plain text.

• Page 9: 10-Point Master Grading Rubric

  A single-page evaluation rubric scoring each station on a clear 0-to-2 point scale for rapid, objective assessment.
