Hi Anto and All,
I am a freshly retired Electronic Engineer and have discovered my long forgotten Lego fun, which I had as a child.
In the local youth club I am teaching kids how to assemble and run little robots made with a 3D printer and An Arduino board and little Servos, you perhaps are aware of the OTT DIY project.
In addition I had a workshop with a robot car kit and all is programmable with Arduino. I am working on a Lego Version of OTTO as well, but that is challenging, because Otto can dance on one foot and the head should not be too heavy as you can imaging.
There is a big Lego Technic box in one of the dark corners of the youth club and the kids are not playing with it, which is a pity so my plan is to make it more attractive when I tell them to motorize the constructions. Another idea is to buy smaller and bigger Lego sets and build it together with the kids.
To train myself I have bought one of the bigger old sets, the 8043 Excavator, build it and played with it. All the gears are great technic, but the model is slow and boring for kids.
Anto, your model looks great and it is fast, but it is not using the 8043 parts. Have started to build it, but found that I have to buy too many new parts.
My Question: Is there a building instruction for an excavator which is using the 8043 parts together with BuWizz and XL, L and M-motors similar to your construction ? If I have to pay something , no problem.
Thank you in advance
Peter
Update: 25.May 2019 Have not found such a model and then mixed your design with the 8043. Thank you for your instructions! It was a real challenge for me to build it, you need to be experienced and I am a beginner. But without your instructions it would not possible at all.
