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.

I have completed the following mods to my G15KS (aka Talos)

  1. Updated all servos to EZ servos
  2. Reconfigure the head & neck servos to make yes/no gestures
  3. Mounted a camera & sonar sensor
  4. Reconfigured the Meccanoid LED assembly for eyes 5. Using EZ-Robot 2.5 Amp HBRidge instead of a Sabertooth (per DJ recommendation) with existing wheels, battery & charger 6. All shelves and boards are clear plastic 7. Added on/off switches
  5. Have done very limited testing

Once the final testing is completed successful, I will be investigating how to use voice recognition/Alexa to get Talos to perform. I found these suggestions to incorporate Alexa to control the robot  https://synthiam.com/Search/using%20amazon%20Echo.

I would appreciate comments & suggestions, thank you.

The Meccano Meccanoids keep evolving thanks to posts such as yours. Here are my RUR Meccanoids all ARC controlled.
