Giving A Meccano G15 Ks An Ez Makeover

StorySkip to comments

Hi there, my name is Tez, I have just completed EZ-Robotifying my G15 KS. Not a technical term but sounds good anyway. All the servos are now EZ and are controlled by the EZ-B v4 controller. The motors that allow the G15 KS to move around are now powered separately by a Sabertooth 2x12 which in turn is also controlled by the EZ-B v4 controller. A camera is present a shown in the images below. In addition to the camera is a Sharp HC-SR04 that is being used to help the ex-meccanoid now know as Jeeves to avoid objects. The meccabrain still remains within the frame as it may be useful later on in drone mode. I am awaiting my EZ grippers to replace the original plastic static hands. I also have a Revolution JD. Kitted out in a similar fashion to Jeeves (ex-meccanoid). Both robots are being used in conjunction with Emotiv EEG headsets. As my aim is to control them using just thought. I can get both robots to carry out actions by facial movements and eye blinking and winking. Pure thought is proving to be a bit difficult. If it was easy it probably wouldn't be worth while. I hope that the images below will show clearly what I have done so far. There is a long way to go yet.

This is Jeeves.

This close up shows my modifications to install a camera and distance sensor. I have also changed the arrangement of the neck and head servos to allow Jeeves to nod vertically for yes and horizontally for no.

Here is a rear view showing the EZ controller and connections and the bracket holding the Meccano battery and the Sabertooth 2x12. The meccano battery means the motors have a separate power supply.

I have also changed the rear wheel castors for for metal ball bearing castors. These give less resistance than the plastic ones from meccanno

Finally, the best little robot a programmer like myself could own. My Revolution JD.

This is the first time I have used the forum. I hope I have used your forum correctly.

In my eagerness to get my work onto the forum. I have noticed some typing errors in the first block of text. I apologise.

hi i found this video.it has info where to choose and download your version

Instead of using an arduino as a bridge, couldn't the uart port on the mecanno Brian's circuit board be used to connect directly to the ezb? The port is not exposed on the case. You would have to cut a hole to get the wires through.

BTW -toys r us has the dev 6 servos on clearance for 4.99 ea.

@DJ Sures

Don't you think Tezsmith's Meccano robot looks a lot like ROBERTO from Futurama!? @tezsmith where did you say you got his brain from?

Just don't go so far as to make ROBERTO 2.0! Then we will have some trouble!

@Bumsteadsean curious what the benefit of talking to meccanoid brain from EZ-B to servos versus an arduino. Sounds like a lot of work and I don't know if there is enough documentation on the MeccaBrain to interface with it. You just need a pull down resistor and you can hang as many servos you want off a $5 arduino, there is an opensource library and there is lots of script examples for EZ-B with Arduino to Meccanoid servo's.

Good point.
