  1. I had no idea they made such kind of mechanisms! Was always wondering how they managed different compensations depending on the angle and the weight lifted, now I have my answer, thank you! Nicely done.
  2. We see in the video of the working prototype some vibration of the planets. do you have any idea for reducing this? silicon on all the gears and moving parts to allow a smoother rotation?
  3. Supporting also, and hoping to have access to building instructions some day!

    Dave Slater Delorean Moc VS Delorean 10300 Video Comparison

    Thank you for this interesting comparison!
  5. Thank you for your answer. The .apk file on the website support page is for Android. Do you have the equivalent for iPad?
  6. Hi Zerobricks, Since the update of the App I cannot connect to the lego Technic Control+ Hub, it doesn't see it at all. Working from an Ipad. I downloaded the legacy App, but how do I get the profile I was using previously? thank you
  7. Great creation, thank you for the detailed and interesting presentation!
  8. Hi, Following the different remarks and discussions, I have reworked a great deal of the rover, and this is the final version that was presented. With robotic arm deployed (4 degrees of freedom): Close-up on the wheel: And the mast: I hope you enjoy it!
  9. Hi. During last days I reviewed commpletely the wheels mechanisms, now the motors are integrated in the structure. The chassis is also lighter and sturdier A Laptop is integrated in the box, for the image processing of the camera that will go on top A simple interface under SBrick allows to control the different functions, of course a background image will be added. Finally, here is a video of the rover in action: Back and forth, tilt/rotation of the camera head, and going left full speed! Now I need to work on the robotic arm in the front, and improve the overall look on top of the box.
  10. You were right, I tried to work on the motorisation and the structure on the middle wheels, and I would make it like this (left wheel on the below picture) The driving motor is now embedded inside the structure Indeed, much better than what I had done previsouly So I guess I'll rework all 6 wheels for the driving motors, and see what I can do with the direction motors also.
  11. It is now around 6.5 Kg. I estimate 10 kg at the end, including the PC and the camera electronics. Thank you for the contructive proposals. The 4 motors for the direction of the outside wheels stick out on top of the wheels as the idea was to make them like the real one: Concerning the 6 motors for the rotation of each wheel, I see two issues, if they had to be integrated into the chassis: - For the outside wheels it would mean having the gears and mechanical links going through the turntable which allows the direction of the wheel, and down to the center, quite complex to make - It was critical to make the chassis as small as possible, but still sturdy enough to hold 10 kg. Currently I have a dimension for the chassis of 3 x 4 studs. If the motor was to be placed as an extension, it would mean adding additionnal liftarms around it to keep it strong enough, therefore increasing the dimensions of the chassis even more. I agree that for the internal wheels motor placement could be improved, myabe by placing them vertically, I'll check what I can do. Concerning the wires for sure they will be hidden at the end :)
  12. Thank you all. Concerning the controller, I checked BC2, but an iPad with a beautiful interface would look more "professional" on an exhibition I believe.
