Obstacle avoidance is the first challenge of our micromouse where the go of making it go straight in a line and also not hit any object is key challenge. To do this we need to build a PCB board where we get an IR circuit where it there are two sensors that can detect if something is to the right, left and straight ahead. The IR is one way of finding objects ahead is how we started but we later changed to a Ultrasonic sensor so we have the advantage of seeing black object. Touch bars are also required for us to retreat and turn if the IR or ultrasonic does not pick up the object in front of it.

The challenges that needed to be met was making sure that it didn’t hit any object and if did use the touch bar to have an appropriate response to it. Making it go straight for 300cm and then show that it can go both left and right.

After the first assessment, to make it more efficient we decided to replace the IR with Ultrasonic so we can have a greater distance and be able to see black objects which was an issue with the IR circuit.
