  1. The top pipe on the ram helps hold it in place as it goes though "Axle and Pin Connector Perpendicular" and all the wight is pushed up on to the the axle on the top of the ram. Its not the best solution but its compact :)
  2. I am still awaiting the arrival of the Mini lego turntable so I decided to work with one of the other grabs in the mean time.
  3. Has any one thought of adding extending outriggers to the unimog?
  4. Thats a really good design. I guess you would add a third motor for the rotation of the whole turntable? The only catch is the arm would start to open or close as the turntable rotates.
  5. How did you connect the two M motors under the turnable? they seem to just hang from a grey frame?
  6. Thanks guys :)
  7. Thats a nice grapple you have there. I have just start a thread on on Grippers / Claw / Grapples your input would be hugely appreciated. Firky
  8. @ Tim: Hi Tim Thanks for concern. I have taken a number of pictures to help show how the mini turntable will fit using parts that are the close match to the turntable its self. This picture hows how the two connecting 1L lift arms on the turntable will connect to the grab. (grab is in open position) This picture hows how the two connecting 1L lift arms on the turntable will connect to the grab. (grab is in closed position) This picture hows how the two connecting 1L lift arms on the turntable allowing enough room for the Axle to fit through. This picture hows how the 28 tooth gear (I only have a 24 tooth gear in the picture) on the turntable fit against to the grab. (grab is in closed position) This picture hows how the 28 tooth gear (I only have a 24 tooth gear in the picture) on the turntable fit against to the grab. (grab is in open position) This picture hows how the 28 tooth gear (I only have a 24 tooth gear in the picture) on the turntable fit against the grab. (grab is in open position) I hope these pictures clear things up. Firky
  9. Thanks for your kind words however, I'm not really sure how or when you can claim a design as your own. I just wanted to be clear that these designs were originally designed by Eric Sophie and Leo Dorst and then modified by me to suit my needs. If the changes made now make this version my design then so be it. @ DLuders: Indeed I do its suited to fit perfectly with a mini Lego technic turntable. The drive axle is dead centre and will fit though the middle of the turntable two 4L axles will hold the turntable in place. I currently don't have a Mini turntable but its in the post on its way here.
  10. I would say they are spot on!
  11. Thanks very much :)
  12. Hey there every one. I am trying to find the best design for a small but strong Grab / Claw / Gripper to use with my Lego robotic arm project. I have found three suitable designs and I have built and pictured them. This grab was designed by Leo Dorst this design is very special as it is symmetrical both sides of the grab open and close the exact same way (Taking in to account the play between the gears) . I have made minimal changes to this design just changed the size for the grab arms and added rubber tips to them. This design is also not centred around the drive axle and would not be easily connected to a turntable. This grab was designed by Leo Dorst this design is very special as it is symmetrical both sides of the grab open and close the exact same way (Taking in to account the play between the gears) . I have made minimal changes to this design just changed the size for the grab arms and added rubber tips to them. This design can easily be connected to a large turntable. This design is very closely based on a grabber made By Eric Sophie over at MOCpages.com. I have just fine tuned the design removing some unnecessary parts as well as replacing larger parts with smaller ones. The grab its now suited to fit with the new small lego turntable. This design does not open or close symmetrically. I am very interested in your idea's and your comments. Thanks Firky.
  13. You could put a large pneumatic ram in stead of the large LA just use one hose off the PPTO to make the ram shorten and the wight of the forklift should make it extend again :) Just an idea.
  14. Well hello there guys and girls. My name is Firky and this is my first post here on Eurobricks. I have been a member for about a week now and I have been looking at all the brilliant ides on this site. Some of you may know me as Firky2010 on youtube and google sites. I have had a Lego robotics project on the go since the start of 2010 my goal was to build a lego robotic arm with 3 or more degrees of freedom and this project is still on going and thats why I have joined up to both share my idea's and find inspiration for my arm. Thanks Firky
