MOVEMENT AND MAPPING PROCESS

MOVEMENT AND MAPPING PROCESS

       The left picture is the maze design that is design with 6 x 6 square. The right one is the robot, the robot will move from down left of the maze. The robot is mark with 1 for forward, left with number 3, right with number 2 and last one number 4 for turn around. The robot first will move through the maze and mapping the way in this table.

Table above show the mapping of the robot that moving around the maze. The number that mark red is an wrong way. The right way of the maze is show below. 

Test the Movement By Using Robot BASIC

Test the Movement By Using Robot BASIC

               This software is used to test the way of controlling and movement of the robot in the maze. This software show the robot is moving by using only the left side of the robot and move in the maze by sensing the left wall only. The robot move are become more waste because the robot will through the maze twice just to map the maze.

SAMPLE VIDEO FROM YOUTUBE

SAMPLE VIDEO FROM YOUTUBE

      

       This video is taken from youtube, the main point of this video is to gain knowledge for the micromouse robot movement in the maze and the idea of the maze design in real competition. This video is showing the robot maneuver in the maze by using two motor and sensor.

THE MAIN BODY AND FULL DESIGN

THE MAIN BODY AND FULL DESIGN

The body of the robot are design follow the spec that have been sketch before. The second picture is the full assemble of the sensor, body, tire, encoder, motor, batteries and the main board robot. The robot is measured to check if there is any problem when turning in the maze.

circuit board

CIRCUIT BOARD

              The component are put according to plan on the main board that have been finish design. After finish, the component are solder to the board. Then, the board is tested to check for any problem.

CIRCUIT DESIGN

CIRCUIT DESIGN

              The circuit is design using PCB designer 1.5. The circuit is compress to get the smallest size to fit the body of the robot. The first board is use as main board that have the microcontroller, driver, button and etc.
The second board is used as splitter board for sensor such as rotary encoder and range sensor.

PCB CIRCUIT BOARD

PCB CIRCUIT BOARD

              This circuit have been design using software and printed to sticker paper.  The circuit is stick to the PCB board and put it into acid bath to created the circuit above. After all finish, the board are drill to put the component on board. 

The sketch of the robot design

The sketch of the robot design

figure above are shown the basic structure of the robot and the size of the robot. The minimum size of each block is 16.8cm times 16.8cm. so the size of the robot should smaller than the block. so i have sketch the robot to the size of 9cm x 10cm. i'm sketch the robot by use the google sketch up 8.

INTRODUCTION

EXAMPLE OF MICROMOUSE ROBOT

qThe aim of the project was to design and build a robot which would be capable of solving a maze confirming to the micro mouse rules.

q The maze in which the robot will be challenged with comprises of a 16 x 16 grid of squares measuring 18cm x 18cm. The mouse will aim to find the centre of the maze, and from there perform a speed run from the start to the centre of the maze, this run is timed, and the aim is to get as fastest time as possible.

q The robot must be capable of propelling itself through the maze and find the centre, the robot will require a vision system to prevent it from crashing into walls. The robot must be fully autonomous and must receive no commands from a remote user.
