Giving A Meccano G15 Ks An Ez Makeover

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.

Ah so im not the only one who had a servo keep moving when powered on?

It was driving me nuts, and so i had to pull my project down and install a new servo to replace it..doesn't move when powered on now thankfully.:)

@proteusy. I am also converting a 4 ft meccanoid to ez control. The meccanoid servo horns will fit Hdd and most other servo's. I would be interested to hear about your progress.

Hi, I am currently using some MG995 servos that I had laying around in my Meccanoid but they suck. They loose position and are not smooth. I am waiting for 8 HDD servos to arrive.

westies

the horns of mecano are in two pieces.when you screw them on a HDD, only the back will be tight.you have to use wacher to bolt them together, on a servo.

@ Nomad 6R Thanks for that. I am trying to devise a walking system using the wheels to do a sort of shuffle. I think the weight will be to great to have servo's moving hinged legs. The idea comes from Mindstorms Ev3 robots.
