Coming Soon......AAI - Adding Autonomy and Intelligence...

Pintegration!.....

Now starting to integrate some Autonomy and Intelligence.

Pi 3 plus standard 5MP camera, working out where best to mount it and decide how its going to talk to the Arduino.

Here's our first test of the pincers.

I'm temporarily on proto wheels which are a bit skiddy and not as good as the Lego tyres, also not stepping at our highest rate while we practice driving.

But really happy it works! :-)

26 January 2020

Modeled up some pincers in CAD for Anthony to print.

20 January 2020

The new assembly drives great in quarter step.

17 January 2020

A friend of the Team donated some Lego wheels. :-)

So we modeled up a wheel joiner and Anthony printed off four of them as well as the new chassis sides.

10 January 2020

After the Christmas and New Year break we have been getting busy again.

Printing a carrier plate for the larger chassis version.

But the whole thing was a disaster and wouldn't skid steer. There was just not enough torque in the motors with the wheels so far apart.

So we have reverted to the original wheel centres.

20 December 2019

We have been experimenting printing cogs we might be able to use to propel Nerf bullets for the Zombie Apocalypse challange.

Also made up a 2nd veroboard for Anthony to develop code on.

28 November 2019

We added a 2nd SMPS and powered the left and right sides separately.

Still uses a single 3S battery though.

Working well with all 4 motors .

Next job is to hook up the microstep inputs to get it going faster.

26 November 2019

Hooray! The core stepper board almost complete.

The SMPS (Switch Mode Power Supply) also supplies the RC receiver and runs at 6v.

However each stepper needs 1A and the SMPS is struggling to start up. Hence only 2 wheels being driven in this video.

8 November 2019

So finally the basic mini chassis is assembled.

We only have 1 RC channel right now.

Need to add a 2nd RC channel to give us forward and back.

31 October 2019

Need more wheels...

Here they are coming hot off Anthony's 3D printer.

29 October 2019

One side working with R/C proportional control and wheels.

Added the RC receiver to the stepper code.

27 October 2019

To improve accuracy in the challenge shooting Nerf darts we decided to model a rifled barrel in CAD then run a test print to try it out.

The competition size chassis is too big for Anthony's 3D printer so we've made a mini version to get things going.

Here's the side panel with a motor mounted to check the fit.

23 October 2019

So we got the stepper motor running with an Arduino Uno.

19 October 2019

Here's our first stab at a basic chassis in Solid Edge.

At this stage there is room to accommodate some gear / pulley reduction if required although we aren't really sure if we need it yet.

The ridges in the wheels are for elastic bands for grip and traction.

13 October 2019

Anthony found these old Lipos in a junk box.

They're from an old laptop battery.

Geoff is going to test them to see if they have any useable capacity.
