In the past few years, we have covered plenty of Arduino kits for STEM education. The EduExo Pro is also worth a look. It is an Arduino powered kit that lets you build your own wearable robotic exoskeleton. It comes with everything you need to assemble the mechanical parts, connect the electronics, and program the microcontroller.
This robotics kit ships with a handbook with info on exoskeleton development, mechanical design, software, control systems, and experiments. The EduExo Pro is connected to your torso, upper arm, and lower arm and has a 6Nm motor in the elbow and a metal spring in the shoulder to give you more support.
