RC volvo ew180d excavator

Human: fusion 360 file: https://a360.co/35C7Ndf This was my first attempt at modeling my own RC model, so it still had some issues that I didn't fix yet. That's why using a Dremel in the building process to sand down some parts might be helpful. The problems that occurred were: - The turret rotation motor was underpowered. - The front blade didn't raise or lower properly because the servos were running in opposite directions. - The cylinder broke due to the way the bolts were attached inside it. - The top frame wasn't stiff enough and bent. - I also had a lot of problems using Arduino to control the machine, and I had too little coding experience. You might want to order a 10-channel remote (such as an Instant FlySky i6s). - When both boom cylinders were attached, they got jammed. - The model was slow. To make it work: - About 3 kg of filament would be needed. - 23 x 10mm outer diameter / 5mm inner diameter / 4mm high bearings are required. - Lego Technic differentials and gears are necessary. - A driving motor with a 25 mm diameter is required (I used one, but I'm not sure what brand it was). - Wires are needed. - A 3/4 x N20 geared motor with a threaded end is required. - Five SG90 micro servos are needed. - Five motor drivers (I used three L298) are necessary. - Bruder wheels are required. - A motor to turn the turret is needed (I used a 28BYJ-48, but it was underpowered). - Five M5 bolts and nuts are necessary. - About 60 x M3 bolts and nuts are needed. - Five 5mm buttons for end stops are required. - A 70cm long 5mm rod is necessary. - A receiver (I used an Arduino Mega for the excavator, an Arduino Uno for the remote, and two HC-modules) is required. I hope I didn't forget any files or information. Good luck!
