My school robotics project: Localization of a mobile robot using a visual system

Robots:

Robot SAMara

This robot was build in year 2015 as a testing project for my new microcontroller (Atmel SAM3S) which is used at my development board. I wanted to learn to use this new MCU so I decided to build a brand new robot and participate in some competitions. The target competition disciplines were Micromouse (maze solving) and RoboCarts (lap-race with multiple robots on a track) so it has differential drive consisted of 2 DC motors with gearboxes and wheels coupled with optical encoders. A 2-axis gyro sensor and 3 IR distance sensors can be found as sensing elements.

Robot specification:

• Atmel SAM3S4B
• 48 kB RAM, 256 kB Flash
• 64 MHz
• 3x IR LED + fototransistor
• 1x Dual Axis Gyro sensor
• Differential drive, 2x Pololu Micro Metal Gearmotors
• Optical encoders
• 1x LiPol, 2s, 7,4 V, 180 mAh
• C (Atmel Studio)

Robot Nite 3

This robot was built in years 2011/2012 with aim to participate robotic competitions and reach better results than its older brother Nite 1. It is improved in fields of dimensions, weight, consumption, acceleration and speed. Thanks to its small dimensions and using of proper sensors is also suitable not only for the Linefollower type categories but also for MicroMouse and RoboCarts. This robot uses experimentally designed PID regulation for line and wall following.

• Processor: TI C28x (F28069 Piccolo USB Control Stick)
• Memory: 100 kB RAM, 256 kB Flash
• Frequency: 80 MHz
• Sensors: 6x QRD1114, 3x TSL262 + IR LEDs, 2x Gyro (1x dual axis Pololu LPY550AL)
• Drive: Differential drive, 2x Pololu Micro Metal Gearmotors
• Power supply: 1x LiPol 2S 7.4 V (180 mAh or 370 mAh)
• Programming language: C (TI Code Composer Studio)

Competition categories:

1. Linefollower / Linefollower Enhanced (following of a line and avoiding obstacles)
2. Micromouse (solving a maze)
3. RoboCarts (a race of multiple robots on a lap)

Robot Nite 1

This robot was my first attempt to build my own non-lego robot. Works on this robot included one of my first circuit & PCB designs, mechanical design ad my first microcontroller programming. This robot also used a PID regulator for line following. It was developed in years 2010/2011.

• Processor: TI C28x (F28027 Piccolo USB Control Stick)
• Memory: 12kB RAM, 64 kB Flash
• Frequency: 60 MHz
• Sensors: 7x QRD1114 + 3x TSL262 + IR LEDs
• Drive: Differential drive, 2x Pololu Micro Metal Gearmotor
• Power Supply: 6x 1,2 V AAA batteries
• Programming language: C (TI Code Composer Studio)

Competition categories:

1. Linefollower / Linefollower Enhanced (following of a line and avoiding obstacles)
