Project Showcase • Dawn Robotics Closing Down - Support Implications

2015-11-17T20:08:47+01:00

Hi all,

Some people may already know this based on this blog post, and the fact that we're running a closing down sale, but if not, unfortunately we're closing down, and indeed may already be closed, depending upon when you read this.

For people who have bought our products, please don't worry that you're going to be hung out to dry, support wise. I'll keep monitoring these forums periodically to try to answer any questions people may have. If you post here and don't get a reponse within a couple of days, please email helpdesk@dawnrobotics.co.uk, as notifications from the forum don't always seem to come through. Also please send me an email if parts you've bought recently, break or are faulty in some way, as I've held back some components to deal with this.

Many thanks to all of Dawn Robotics' customers over the last couple of years. It's been fun.

Regards

Alan

Hi Alan,

It is running remote on a W8 computer. The script is rather straight forward to keep the coding challenges low (for me). So, I had to take some shortcuts in the solution. In the Google-blog I describe the reasons.

Then one of the two major challenges was of course the timing. I think the sample_time is on the edge of workable. Using py_websocket_bot I couldn’t get it much lower than 0.05 anyhow.

The timer generates weird peaks even when working in plain Python without your classes on several computers. I’m not sure if that’s due to Python. I’ll want to recode the script in C/C++ once, to find out if that’s the case.

The other phenomena was the difference in performance between the left and right motors. I could get one side working with a perfect graph. The other side fell short on the max PWM. Thus resulting in too much weight of the balancing loop in the controlled part. In the blog I mention almost everything I tried, but I’m still guessing for a solution.

Anyhow the outcome is satisfactory as an intermediate result. I’ve just ordered the Grove compass. I’m curious if I can add that while still using py_websockets_bot.

The epic after that will be trying out the improved Dagu mini driver. I’m thinking of building the control loop, including the compass, in Arduino. The memory should be sufficient now, I think.
That will leave me the Raspberry (also probably Model 2) to work on locating and mapping, incorporating vision control. (I might be needing your help in implementing the new Dagu board in py_websockets_bot)
And of course I’ll try more qualitative encoders as well then. (You’ll have them launched at your store by then, I hope). ;-0)

So still a lot of fun ahead and I’ll be back when I’ve something I can share.

Cheers,
Bastian

Hi Bastian,

That looks really good. I haven't looked at your code in much detail, but I'm really impressed that you got your control loop to run using py_websockets_bot (i.e. not within the web server). Were you running oyur control script on the robot, or on a separate computer?

Project Showcase • RB Running Squares

2015-06-16T22:35:08+01:00

Hi there,
I have been digging in on some odometry topics and got the bot running in (rather) straight lines at a certain speed for a certain distance using optical encoders and 3 PID’s.

The video isn’t thrilling, but shows an intermediate result in calibrating the positioning and RB almost finishing a full square with a total perimeter of 12.2 meters.

Video:
https://www.youtube.com/watch?v=8z0CsYaxo8Y

For those who are interested, the following blog contains a more detailed description of the background, approach and a way to use squared runs for further calibration:

https://plus.google.com/113179308235478830494/posts/UiFYacTvDLr

If wanted remarks, suggestions and/or questions can be dropped there as well.

The Python script can be found at:
https://bitbucket.org/RoboBasics/raspberry-robo-cars/src/8df278bd8786da754462197c3b553d1aaa40f599/Scripts/Odm_2_running_squares.py?at=master

I noticed in the forums that several people raised questions on having the robot running straight. The bitbucket repository also contains a Python script for mere proportional correction of the wheel differences. If just straight driving is desired, this script might be helpful.

The approach is a bit raw (left out some things like the acceleration), but it provides a good start for further exploration.

For sure I will work on some improvements in the future (and surely acquire some magnetic encoders for better actuating).

For now I will be working on adding digital compass data to the control loops (or replacing the balancing loop by a compass loop)

Enjoy !

Actually, now looking at the links pasted above, I see the AS BluetoothChat sample is horribly and deliberately made more complicated than probably ever needed... for the need to cater for different screen sizes mostly (like, different form definition for every other resolution, and all that mapped dynamically, omg.)

As of it working, I can definitively confirm, it does, on my MotoG 3G 2013 and on my Google/Asus Nexus 7 2012.
With sliders (SeekBars) for throttle and steering, and sending it text commands.

One thing I'd probably LIKE to do is to somehow add a feature to rename the BT receiver from HC-06 to something more, say, freeform. But this means the MD will need to send some AT commands at some specified speed to it probably. Which I hope won't be on their way to fry it.... Ever tried that?

Hi,

Then I'll have to replicate the code for sending strings to the BluetoothChat service, one that is in the BluetoothChat Fragment (https://android.googlesource.com/platfo ... rvice.java and around this is what I presume I've imported...)

(this https://android.googlesource.com/platfo ... hChat.java especially lines 206-221)

which I certainly hope will go well...

I am sorry, really... my Java skill level is approaching 0 exponentially ;J the more I read the less I understand of it

I'm flailing here as I don't have the IDE installed yet but have you created a variable for the SensorActivity and initialised it? Something like

Code:: SensorActivity mSensorActivity; // This goes with the other member variables mSensorActivity = new SensorActivity(); // This goes wherever your setup code is

Looking at the sample you should just then need to put some printing code in the onSensorChanged code to see readings from the sensor. To get those sensor readings back into your control code you've got a number of options but essentially you need to use a callback that passes back the data.

Apologies if this is way off or completely unhelpful. I'm interested to see how this Android Bluetooth stuff works so will do my best to install the Android tools later this week. Then hopefully I can make some more sensible comments.

Regards

Alan

Hi,
so, googling for answers how to integrate the motion (axis angle/gyroscope sensor) into my project, i found an interesting page http://developer.android.com/reference/ ... nager.html and a few others but this seems like something ... only have no clue how to integrate this .

I added the snippet as is to a file (bar it did not like that the class was public) and took AS's suggestions so it wouldn't error out. But now since my sendmessage() is in a different class (the Fragment...) i need to do something else, but what?
This http://developer.telerik.com/products/b ... eter-data/ looks simpler... but still no clue how to add that so it would work in an existing fragment/java class...
Yeah I know it's noobish. Please help/point... I am after the left/right turn and front/back turn angles so to use the device as a throttle or steering wheel.

Yay thanks this worked,
also i finally got what the AS wanted of me... the prototype of the OnSeekBarChangeListener onProgressChanged to implement, looks different...

Code:: mSteeringBar.setOnSeekBarChangeListener( new SeekBar.OnSeekBarChangeListener() { @Override public void onProgressChanged(SeekBar seekBar, int i, boolean b) { ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ // i had something else ;) even if still technically same types of variables... int aposition = i - 16; String message = ""; if (aposition < 0) { aposition = -aposition; message = "L".concat( Integer.toHexString(aposition)); } else { message = "R".concat(Integer.toHexString(aposition)); } sendMessage(message); } @Override public void onStartTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } @Override public void onStopTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } });

So now onwards to do a fully on-sliders app

Hi there,

I think that what your compiler is saying is that you also need to provide an override for the method onStopTrackingTouch. This question on stackoverflow has a snippet which looks similar. So bascially you may have some joy by adding these 2 overrides

Code:: @Override public void onStartTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub } @Override public void onStopTrackingTouch(SeekBar seekBar) { // TODO Auto-generated method stub }

And now I'm trying to extend the BluetoothChat example further, by putting in a SeekBar, to do this:

Code:: // mSteeringBar.setOnSeekBarChangeListener( // new SeekBar.OnSeekBarChangeListener() { ^^^^^ when uncommented, this line goes red with error below ^^^^^^^ // @Override // public void OnProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { // int aposition = progress - 16; // String message = ""; // if (aposition < 0) { // aposition = -aposition; // message = "L".concat( Integer.toHexString(aposition)); // } // else // { // message = "R".concat(Integer.toHexString(aposition)); // } // sendMessage(message); // } // });

It's in comments, because it won't let me
it says

Error:(287, 55) error: is not abstract and does not override abstract method onStopTrackingTouch(SeekBar) in OnSeekBarChangeListener

Pls help, I so don't understand this error

So I programmed some more buttons (basically extended the Bluetooth Chat example by another set of buttons, each one sending a command,
and it goes well, as far as sending text commands at button press can go

Also the discussion about b/o protection just about to take an unexpected turn: i changed batteries for a new set of 5 x aaa...

and now, pf and tf command does not brown out any more and the speed, it's MASSIVE
can't wait to test it outdoors.
