Review on Enhance Your DIY Robot Project with the LAFVIN 4DOF Acrylic Robot Mechanical Arm Claw Kit — Perfect for Arduino IDE with CD Tutorial! by Maria Aguillon

Documentation on DVD is included with the product. Minimal documentation. Nothing is said about which screws to tighten and how tight to tighten them. Eventually, some of the screws will become too tight and become inaccessible without disassembling the entire robot. It happened to me on a servo. But the other servos didn't work either, except for one. I'm an engineer and I was very surprised by some of the design decisions. It's impossible to hold things in place and twist them without pliers and adult strength. I didn't even ask my grandkids (7 and 9 years old) to join. I spent almost a whole day assembling this robot. Finally see that it doesn't work. I have to disassemble it to get to the broken screws. I'll do that, but I won't reassemble it. I leave the electronics, servos and cables and throw the rest in the trash.
