Robotics

This model was meticulously engineered for versatile operations, extending beyond its primary function of line-maze solving to include obstacle avoidance and wall following. A standout feature of this design is its remarkable capability to navigate slopes as steep as 45 degrees while maintaining line tracking. 

Achievements

The schematic is crafted to enable flexible customization of parameters and logic. This adaptability is facilitated by a user-friendly menu system, navigated via push buttons and displayed on an I2C OLED screen. This design eliminates the need for reprogramming the robot through a laptop whenever adjustments to logic or parameters are necessary. 

Performance

• Efficiently navigates and solves any type of line maze.

• Detects and avoids collisions with obstacles along the line.

• Can climbing slopes with an incline of up to 45 degree.

This model is crafted to be lightweight, prioritizing high-speed operation. The design strategically centers most of the weight above the motors and wheels, enhancing traction and maximizing performance. 

Features

This version of our robot features a 14-sensor IR array paired with a multiplexer. It is powered by high-speed planetary gear motors and a BTS-7960 motor driver, ensuring exceptional speed. 

Performance

This version of the robot incorporates a curved IR array and a camera as advanced sensing elements. The camera enables the robot to anticipate sharp turns by identifying the approaching line type, allowing it to decelerate proactively for smoother navigation using PID control algorithm for faster response to mitigate the positional error. 

Features

The primary circuit in this version remains largely similar to the previous one, with the key enhancement being the addition of a curved sensor. Furthermore, an advanced sensing system has been introduced, integrating a camera, a Raspberry Pi Pico, and a TFT display for improved functionality and versatility.

Performance

This version features major structural enhancements, including a redesigned lightweight chassis with 80% of the weight strategically distributed over the wheels. Additionally, two coreless motors are positioned above the wheels to generate extra downward thrust, significantly boosting stability and traction. 

Features

The key updates in version 2 include a switch to the Raspberry Pi Pico as the primary controller, replacing the Arduino Nano. The motor driver has been completely customized for enhanced performance, and a menu system featuring an OLED display and pushbuttons has been incorporated, providing greater functionality and ease of use.
