**Pick a project, check the parts, calculate before you buy, fix what breaks.** This is the maker and student door of the site. Every build is costed in rupees and every guide says where it can fail.

## 1. Choose a build

- [Projects: costed build sheets with parts lists and pin maps](https://roboticsengineering.in/projects/)
- [Free final-year project pack: shortlist, report outline and viva questions](https://roboticsengineering.in/free-project-pack/)
- [Three robots under ₹2,000](https://roboticsengineering.in/robot-under-2000-india/)
- [How to make a robot at home](https://roboticsengineering.in/how-to-make-a-robot-at-home/)

## 2. Check the parts

- [Component guides: motors, drivers, sensors, boards](https://roboticsengineering.in/components/)
- [L298N vs TB6612FNG motor drivers](https://roboticsengineering.in/l298n-vs-tb6612fng/)
- [Best Arduino board for robotics in India](https://roboticsengineering.in/best-arduino-board-for-robotics-india/)

## 3. Calculate before you buy

- [All calculators](https://roboticsengineering.in/tools/)
- [Servo torque](https://roboticsengineering.in/servo-torque-calculator/)
- [Battery runtime](https://roboticsengineering.in/robot-battery-runtime-calculator/)
- [Gear train](https://roboticsengineering.in/gear-train-calculator/)
- [Wheel speed and RPM](https://roboticsengineering.in/wheel-speed-rpm-calculator/)
- [LED resistor and voltage divider](https://roboticsengineering.in/led-resistor-voltage-divider-calculator/)

## 4. Fix what breaks

- [Error library for Arduino and ESP32](https://roboticsengineering.in/fix/)
- [Arduino robot not working](https://roboticsengineering.in/arduino-robot-not-working-troubleshooting/)

## 5. Learn and plan a career

- [Learning guides](https://roboticsengineering.in/learn/)
- [Careers in robotics](https://roboticsengineering.in/careers/)
- [What is robotics?](https://roboticsengineering.in/what-is-robotics/)
- [Twelve-month skills roadmap](https://roboticsengineering.in/robotics-skills-roadmap-india/)

Working in a factory instead? Use the [Automate section](https://roboticsengineering.in/automate/).

Writing a report or preparing for a viva? Use the [Free Library](https://roboticsengineering.in/free-library/): report outline, viva questions, bill of materials and test log templates.
