SaperPL Posted May 15, 2022 Posted May 15, 2022 The photos are amazing. The "logs" are awesome trick. Video is really cool as well, although it shows limitations of what you can and cannot do at this scale (speedy movement of pistons, holding the vehicle to not tip over, manual operating end of the arm). I'm also having issues with movement because there's no proportional control in my CADA hub. I wonder if we'll have someone who has a machine that has additional functionality over just movement and tipper, that will be perfectly executed in context of those movements. Quote

Yes, "logs" are not quite ordinary . Because if you fully load the claws with heavy wood of great length - it will weigh more than the loader itself. Even with such light logs at full load and with the boom fully extended forward, the machine is on the verge of tipping over. But the cover opens at the back and you can add additional weight for the counterweight (in fact, I held the model not so that it would not turn over from the weight of the load, but in order not to turn it over when the pump was pressed, because the effort required is quite large) You are absolutely right about the restrictions. These are the limitations of the functions of pneumatics, and the tensile strength of Lego parts. Therefore, if I have enough inspiration after the competition, I will make this loader on a larger scale without pneumatics, completely on control +. This is a minimum of 6 functions (7 with pusher slope), so 2 hubs are needed. According to my calculations, this will require a wheel scale no less than the wheel of Zetros. But that will be later...maybe... Edited May 15, 2022 by Akassin Quote
