I Can 'C' Clearly Now ...

I was intending to move on from the Tidy The Toys challenge. However, after the announcement that this year's competition has been delayed I decided to revisit it. 

Time, time, time ....

So today it was announced that both Pi Wars 2021 dates have been moved from March to July due to problems of teams collaborating during the current lockdown.

HC-SR04 - Every Microsecond Counts

In Pi Wars 2019 we had a lot of success with using HC-SR04 sonar distance sensors on our Sputnik robot. 

Those Toys Won't Tidy Themselves!

Blogs are like buses - you wait all month to post one, and then three come along at the same time.

But what else are the Christmas holidays for if not working on Pi Wars and catching up on the blog. 

Moving in a Straight Line

In Pi Wars 2019 there were 2 tasks that involved moving in a straight line between two walls. To achieve this, we had sonar distance sensors on each side of the robot, and code that determined the angle we were travelling at and tried to correct it to keep within the centre of the two walls. 

Where Are The Toys?

For the "Tidy the Toys" challenge we need to be able to locate the different coloured blocks so we can move towards them, pick them up and take them to the target zone. Actually we're also planning to use another colour to identify the target zone. The only practical way of doing this is to use a camera and process the image to find the coloured blocks.

So - we have a robot - actually we've had a robot for a while, but my blog writing hasn't caught up.
