Objective
The main objective of the competition is to design a manually controlled robot which can move on land as well as water.
The robot needs to collect the coins already kept on the field and place them in a basket.
Electrical Aspect
The Diathlon competition is basically a test of mechanical aspect of robotics, in the sense that the electrical arrangement is relatively trivial.
Like in any manual robot competition, we need to move the wheel motors in both the clockwise and anticlockwise direction.
To turn the robot, we run the left and right motors in opposite direction.
The sense of rotation of a DC motor can be reversed by simply reversing the direction of applied voltage.
A crude way to achieve this is by using a normal switching circuit. However switching at high currents has its disadvantages. It leads to sparks inside the switch which is not desirable.
Micromouse – Building Blocks
Side- looking sensors to measure the distance from the wall and detect their absence/presence.
Sensors are the most critical of all the systems. The accuracy of the micromouse relies on the quality of sensors.
