Remote Controlled Robots

Dear Bloggers,

4/5y, 5/6L and 5/6H designed, built and programmed remote controls for their robots.

The photos below show 4/5y practising for the up and coming ‘Robot obstacle Course’

Sometimes things really are ‘black and white’

Dear Bloggers,

This week stage 3 children were challenged to write a program that allowed their robots to progress and stop through a series of black lines.

To do this students had to add a light sensor and use the view menu on their robot to read the amount of light (%)  reflected from the black and white surfacse.  Using this knowledge they programmed their robots.

light sensor must be facing downwards

Using the light sensor in the view menu to measure and read the amount of  reflected light.

Mrs Garlick’s Level 3 Solution to closing the Dam.

Dear Bloggers,

Have a look at the video below to see my Level 3 answer to closing the dam.

My robot has a touch sensor, light sensor and ultrasonoic sensor.  There is a sweeping heading that moves to collect the plug wherever it is positioned and then sweeps again to find the hole in the dam.

4/5 Y revisit closing the dam

Dear Bloggers,

4/5Y, 5/6H and 5/6L were given the arduous challenge of closing the dam.  All students across the stage attempted to plug the dam with the large bung, release and capture the energy brick and return it to base.  Attempt no.1 was lots of fun and there were many wonderful designs.  However, the children of GEPS, were not allowed to rest there.  In class we revisited videos of their first attempts and using their superior problem solving skills we brainstormed new and better designs and programs.  Hence for attempt 2 the ‘bar was raised’.  This time the student had to use a sensor, build a capture device to retrieve the energy brick and this time only use a limited set of resources.  The students engaged readily in this problem solving activity and produced some excellent results.

See for yourself below.

Mrs Garlick’s solution to the Green City Challenge – deploying the chimney stacks (Level 3)

Dear Bloggers,

Below are some photos and a video showing my response to the Green City Challenge.

The robot started from the base area, moved to the factory and picked up the white chimeny stack and knocked down the black one.  This released the energy brick which rolled out and was caught in a tray.  The robot then returned to the base area.

My robot had different attachments:

1. a light sensor so I could position the robot by detecting the black lines.

2. an arm with a hook that could pick up the white chimney and knock over the black.

3. a tray to catch the energy brick.

I also used a touch sensor to control the  hook so I could place the hook in the upright 12 o’clock position to start.

4/5Y Clean Up That Dirty Old Factory

Dear Bloggers,

4/5Y spent two hour lessons last Wednesday and Thursday trying to deploy the new chimney stack onto the Green City Factory.

Green City Videos from other schools

Dear Bloggers,

Other schools have completed the Green City Challenge and here are some of the videos which I have carefully checked from the inter net.  Have a watch if you are interested.
