    Arm update The issue with the wobly rotation of the crosses is solved. Due to the universal joints it stays wobly, whatever i did. ti got rod of those and now i used the CV joints for a small angle and a rack with 90 degree angle gears. It works awesome, very very light rotation and no wobbling anyore :)

    Auto Run Module Next is the rebuilding of the auto runner. It was too lumpy, to big and worked not the way i wanted. so i rebuild it in a more efficient way. The principle is simple. A hub on a chain is running around the device an on the way it pushes levers that operates the functions. The challenge is to stop all the functions on the end of the chain. Polyp by But the biggest challenge is preventing damage to the model due to incorrect timing of the functions.The motor that does the lifting of the polyp must be active for only ± 10 seconds and then stops. With only a pushlever it can not work properly, Solved problem lift function The polyp has a lift and the timeperiode of lifting up must be exactly te same as lifting down, otherwise is will damage the structure. The pushlever for lifting activates a motor that pushes the lift up. With a chain running on the runmodule it can happen that for some reason the chain is going slower through the pushlever for the lift going down i will have a problem. The solution is 2 motors. 1 motor that lift the model and 1 motor for activate a pushbeam that rotates and set the Legoswitch back to zero. when the lift must go down, the sequece is the opposite way here is a photo of the new run module: It will be a closed device as a box, but these are the internals. here is the pushbeam visible (1 of 3)

    ok guys..let me start with the exentric(the middle drum with the liftsystem. The.previous one had a ticking gear. So i decide to rebuild it. An extra shockabsorber to make the lift easer, 2 paires of gear slider racks and a very sturdy housing. The drum is now a compacter and easier acces to the motor and the racks in the case the gears break. Added will be new (red) micro leds so that is later on. here is a photo of it

    Hi everyone, Iam back to business with the Turbo Spider. The project was stopped due issues in the family, corona and more things. This year i finally was be able to work on the model. This year is also the LegoWorld here in the Netherlands so it made me push myself to get te model off the shelf again. it was (is) in 20 pieces on the workbench since the last exhibition. The last run was in october 2019 and i notice there awere still a LOT of issues with the model, so iam upgrading the model now. The main drive system was "ticking", the lift was ticking, the crosses were rotating very wobbly, the auto run module was not working the way i wanted, the excentric wasnt very reliable and the fences were not what i had in mind. So......i upgrades are these things, getting rid of the flaws, making it better. The auto run module is rebuild completely in a more efficient way This week i will post the progress photos To be continued!

    No. Im alive and well. But due to corona and the loss of my father last year, the build is on hold for a wile. My plan is to be prepared for the next Lego Exhibition but everything is canceled now. So...more to come, but not yet. Ps: the polyp still exist, but now on the workbench: )

    Why not use a differential gear? Only thing with that you must lock the big gear

    This is how the slipring / drag contact looks like. very simple actually.

    Jo! Thnx. The seats are indeed a bit to high from the floor. I am adjusting that right now. My plan is to use actuators that holds the arms (,easy to adjust). The whole mid section will be rebuild. About yr questions: No silicon spray is used. My experience is that spray or lube attract dust and moist. The turntable on the head (type 3) is perfect. When its run oit, i easy can replace it. 2 pieced of half beams 4l with copperfoil on it does the job. No brushes. Perfect conductive and no volt drop. I will add a picture today here. I have a manual controldevice next to the autorun module. The video of the run with the Auto run module is in progress. And indeedz my plan is to make a switch on it for changing. Ny changibg the angle of the head i also need to change the connection of the arm.(higher connecting point)

    Very impressive!awesome!

    Thnx a lot man. And guess what. There is more to come. My plan is to rebuild the excentric more compact and better lift. I want the head in bigger angle
