New development board for robotics.

Hello!

I hope it's the right place...
I would like to introduce a board I have developed as an "after 5" job.


It's called REOBoard. As explained on the website, it can drive simultaneously 4 DC motors
(500 mA each for this version) and 6 servos. You can also replace a pair of DC motors to drive
1 stepper motor.
The processor is a MSP430F5659 running at 24 MHz.
Among other interesting features:
- I have developed a scripting language for robots. For example,
if you want to do a servo loop (e.g. a potentiometer and a servo motor), it takes you only 5 ~ 6 lines
to write the program.
- It can also receive bluetooth messages, and the interesting thing is that I give the source code,
both for the microcontroller and for Android (it's already downloadable). I have also an iOS application,
not published yet. See the demo on youtube:

- There is also an android voice recognition app, but it's still in a very early development stage.
It will be eventually delivered on the same website.

That's about it!

Good work.

BT Latency and control hysteresis will be a challenge for fast driving.

PID loop control may help a bit with 0 deg steering calibration. e,g, or rate control for sharp left/ right ( high diff. gain (D)) and tilt for gentle steer (P) and level for auto zero 0 deg. (I) for straight line.

Not quite the same performance as WII IR Remote control but nice proof of concept and great user interface.

Hello!

Yes, I know what you mean. The commands look a little bit jumpy, but it's due to the message
pace that cannot be that high for BT4. Anyway, I didn't spend much time on the development, and
I'm sure there are methods to do it smoother. Anyway thanks for the feedback.
