The Triad of Modern Robotics

Entering an undergraduate Robotics Engineering program quickly clarifies why robotics is uniquely challenging: it sits precisely at the intersection of three disciplines:

  1. Mechanical Engineering: Statics, dynamics, material selection, kinematic chains, and CAD tolerancing.
  2. Electrical & Electronics: Power delivery, microcontroller architecture, signal integrity, and sensor interfaces.
  3. Computer Science: Algorithms, data structures, real-time operating systems (RTOS), and distributed frameworks like ROS 2.

At the beginning, the sheer breadth of tools can feel overwhelming. Balancing differential equations in calculus with C++ memory management and 3D print troubleshooting is an intense mental shift.

What I Wish I Knew Before Day One

1. Hardware Bugs Look Like Software Bugs

A common trap is spending hours debugging control loops in code when the true culprit is a loose ground wire, a sagging power supply, or mechanical backlash in an inexpensive gearbox. Debugging robots requires investigating physical reality before assuming your logic is faulty.

2. Math is the Real Engine

It is tempting to focus entirely on assembling hardware kits. However, as robot kinematics grow from simple 2-wheel rovers to 6-DoF robotic arms and humanoid bipedal walkers, linear algebra, vector calculus, and state-space representations become essential tools for writing controllers.

3. Build in Public

Documenting small milestones, failed prototypes, and architectural diagrams helps crystallize understanding. This website was born from that exact realization: writing things down turns temporary lab struggles into long-term engineering insight.

Goals for the Upcoming Year

  • Complete coursework in linear algebra, multivariable calculus, and physics mechanics.
  • Transition from Arduino C++ to modern C++17/20 on STM32 / ARM Cortex-M microcontrollers.
  • Learn ROS 2 fundamentals and URDF robot modeling in Gazebo / Isaac Sim.
