[Yr7-10it] Robotics hardware and software choices , capabilities and pricing

[Glenn Demery]

We have also been using the NXT kits. I found them easy to use (and learn as I had not taught it for a long time).

A particularly good project was to produce sumo robots. Each group produced a sumobot that would fit inside a 25 cm diameter circle but after that they had free reign.

A competition was held against groups from within the class, then against the other class. 
A large circle (1m diameter) with a dark black line around the edge was made. The sumobots had 2 mins to either push the other robot out of the circle or turn it over. 
Whichever sumobot left the circle first or was turned over first lost.
Some students used the sensors to spin until they located the opposition. Others just move randomly until touched the opposition. Others made big collecting claws, where others went with the scoop approach.

There are plenty of youtube videos for students to investigate different designs.

This unit proved popular with both boys and girls and many initial designs were tested, rejected or improved upon.

I have taught year 9 robotics for about 5 years.

We bought 10 of the Lego Mindstorm kits (the old ones) and Robolab version
2.5.4. This has held us in good stead over the last few years. We did buy
a new Lego NXT kit, but it doesn't have as many parts, though there are
some "cool" new things you can do. I also purchased rechargable batteries.
Over time, the wheels of these robots wear out hence the robots don't
always move dead straight with the old kits. Each kit comes with a book
showing how to build the robots and assorted attachments (eg: a robot claw
or crane). The old kits had heaps of lego parts, so that's why I still use
them instead of upgrading to the new kits.

With Robolab, it's an icon based programming software, so it is easy for
students to connect motors and get them moving. Because it's picture
based, students pick it up fairly quickly. We used notebooks in class for
the programming.

We built some wooden shallow boxes for students to test their robots in so
they don't fall off the tables. I'd advise doing it a science lab with big
benches so you have lots of space.

The course consists of a series of exercises in a group to learn the
building / programming followed by a group assignment. I added some art
elements where they can decorate the robot, make a "stage" or set where
the robot(s) perform, etc. Students also had music whilst the robot danced
or performed another function. Students also videod the performance of the
robot, including testing stages where things didn't work.
