#How to Code Your Own Electric Car and Enjoy the Drive

How to code automatic line-following programs

The electric tram silently accelerates, showcasing features like rapid acceleration and zero emissions, distinguishing it from traditional gasoline-powered vehicles. Many electric trams utilize driving techniques from automatic gasoline cars to help drivers adapt easily. Have you thought about creating a program that simulates driving, including the use of a brake pedal?
Following this # How to, you can design and complete programs for the tram's cockpit and the control system of the small car chassis.

Importance of Brake Pedal

The brake pedal is crucial for a robot car (or autonomous vehicle) for several reasons. While autonomous vehicles typically don't have manual controls like traditional cars, a "brake system" or its equivalent—whether in the form of a brake pedal or an automated braking mechanism—plays a vital role in ensuring safety and performance. Here's why it's important:
1. Ensuring Safety
Collision Prevention: The primary function of any braking system is to prevent collisions. Whether a robot car is navigating complex environments or driving autonomously, the ability to stop quickly in response to obstacles is crucial to avoid accidents.
Emergency Stops: Brake systems provide a fail-safe in situations where the vehicle’s sensors detect a sudden obstacle, a malfunction, or a potential hazard. Autonomous cars, just like human-driven ones, need to respond immediately to unexpected events.
2. Precision in Motion Control
Controlled Deceleration: The brake pedal (or automated braking system) allows the car to decelerate smoothly rather than stopping abruptly, which is important for precision in maneuvering around tight corners, parking, or adjusting speed in response to traffic or other environmental conditions.
Stopping Accuracy: For tasks such as autonomous deliveries, parking, or pick-up services, the robot car needs to stop accurately at specific locations. A braking system is essential for achieving such precision.
3. Ensuring Smooth User Experience
Comfort: A braking system that can modulate force ensures a smooth ride. Abrupt stops or uncontrolled deceleration can make passengers uncomfortable or cause damage to fragile cargo in delivery robots.
Human-Override Functionality: In semi-autonomous or remotely controlled robot cars, brake pedals provide an option for manual intervention, allowing human operators to take control in cases where automation fails.

P - Park: This mode locks the transmission, preventing movement when the vehicle is stationary and parked, ensuring safety when the brake pedal is released.
R - Reverse: In this mode, the car moves backward. It’s used for backing up and requires the brake pedal to be pressed for safety during engagement.
N - Neutral: Neutral disengages the transmission from the engine, allowing the car to roll freely without engine power affecting it. This is useful when the vehicle needs to be pushed or towed.
D - Drive: In Drive, the car moves forward. This mode is for regular driving, and the brake pedal is crucial for controlling speed and safely shifting gears as needed.
