Problem

Traditional lawnmowers have long been a staple of lawn maintenance, but they come with a range of challenges that can impact usability, as for example:

1. Physical Strain: Pushing or maneuvering heavy traditional mowers can be physically demanding, especially for individuals with limited mobility.
2. Limited Accessibility: Traditional mowers may be challenging for certain demographics to operate, such as the elderly or individuals with disabilities.

Solution Scope

Solution Statement A Robotic Lawnmower System that addresses the challenges associated with traditional lawnmowers while promoting ease of use, accessibility, and convenience.

Our solution, as it's functioning will be better explained in the next sections, it's to solve the problem for specific garden conditions. Those conditions are:

• The garden should be surrounded by a wall or object that has at least the height of the Lidar sensor (around 30cm). The grass should not be too tall (above 7cm) before cutting it.
• The maximum area of the garden is 25m² and it has to able to connect to the internet within the area. The area was found by the calculus using the battery duration stimation, wheel circunference and the motor RPM.
• The garden is for domestical purpose, so the land should not be too tough and not surpass a slope of 15 degrees
• Obstacles on the garden should be of the same height (or higher) than the LiDar sensor. And there can be dynamic obstacles.
• Steps need to be the same height or higher than the LiDar sensor.
• The robot will operate just under clear weather conditions.
• The grass should be one of the following types: Grama Zeon Zoysia or Grama Geo Zoysia

Idea

General Operation

In the first use, the user will control the robot via an app, giving commands such as go forward or make a turn, to set up a cutting path. This way, the robot will already know which path to take to cut the grass. The robot will have an internal battery and a charging base, at the end of the journey or when the battery is low the robot will automatically return to the base to recharge its battery, this base is waterproof and protects the robot from rain and wind.
