SunFounder 4 DOF Robot Arm Kit with Shovel Bucket, Hanging Clips, Electromagnet, Support Graphical Visual Programming, Python, Remote Control Multifunctional Robotic Arm for Raspberry Pi 4B 3B+ 3B

I bought this robotic arm kit as a step up from another arm I have. This one is almost all metal with seemingly higher quality servos. The remote control works well but I found it to be a little small for my hands. This wasn't a big deal for me since I'm using Python to control the arm and it seems to fit my 8 year old son's hands just fine. My favorite part of this robotoc arm is the fact that I can switch the attachments - the claw is your typical "hand," the bucket shovel is good for playing in the sand or scooping up Lego, and the electromagnet, my favorite, is just all around fun! The magnet isn't super powerful but it's powerful enough to hold on to anything the arm can handle (meaning you can't pickup something that's too heavy for the arm).This quickly became my favorite RPi project and one that I'll be building on for awhile.
