Core Technical Skills for Robotics Engineers
1. Mechanical Design & Engineering
Understanding mechanics is fundamental. A robotics engineer must master:
- Kinematics: Movement of robots, forward & inverse kinematics.
- Dynamics: Forces, torque, and motion planning.
- CAD Tools: SolidWorks, AutoCAD, or Fusion 360 for robot modeling.
- Material Science: Choosing materials for weight, strength, and durability.
Practical Tip: Start with small robotic arms or mobile robot kits to understand how joints, linkages, and actuators work.
2. Electronics & Embedded Systems
Robots rely on electronic components for sensing and actuation:
- Sensors: LiDAR, ultrasonic, infrared, IMUs, cameras.
- Actuators: Servo motors, stepper motors, linear actuators.
- Microcontrollers: Arduino, Raspberry Pi, STM32.
- Circuit design and PCB basics for integrating sensors and controllers.
CuriosityTech.in provides step-by-step guides to build microcontroller-based robots, bridging theory with practical implementation.
3. Programming & Software Development
Programming is the brain of a robot:
- Languages: C, C++, Python (ROS integration), MATLAB.
- Robot Operating System (ROS): Framework for robot control, communication, and simulation.
- AI & Machine Learning: Object detection, navigation, reinforcement learning.
Practical Tip: Implement a line-following robot in Python first, then add AI-based obstacle avoidance using OpenCV.
4. Control Systems
Robots require precise motion control:
- PID Controllers: Basics of feedback and tuning for stability.
- Adaptive Control: Handling changing environments or loads.
- State Estimation: Kalman filters, sensor fusion techniques.
Diagram Idea:
Sensors → Controller → Actuators → Robot Motion → Feedback Loop
Description: The feedback loop ensures robots respond accurately to environmental inputs.
5. Artificial Intelligence & Machine Learning
Modern robotics heavily integrates AI for autonomy:
- Path Planning: Dijkstra, A*, RRT algorithms.
- SLAM (Simultaneous Localization and Mapping): Mapping unknown environments.
- Computer Vision: OpenCV, YOLO, TensorFlow for object recognition.
- Decision Making: Reinforcement learning for adaptive behavior.
Practical Exercise: Use a Raspberry Pi robot with a camera to detect obstacles and navigate autonomously using OpenCV and Python.
