LewanSoul Robot Hand Five Fingers Solely Movement Bionic Robot Mechanical Arm DIY - Right Hand with Servo Tester

This robot hand kit is suitable for basic DIY and educational projects. The mechanical structure allows individual finger movement, which makes it useful for learning about linkages, motion, and simple robotics concepts. Parts arrived intact and matched the product description. Assembly requires some patience and basic mechanical understanding. This is not a finished product out of the box, but rather a hands-on build meant for experimenting and learning. Once assembled, the fingers moved as intended when actuated, and the range of motion was good for demonstration purposes. Overall, this is a fun project for hobbyists, students, or anyone interested in basic robotics and mechanical design. Best suited for learning and experimentation rather than heavy-duty use.

This combination works great. These little sensors are very fast and they vary resistance well with light touch, medium touch, full pressure. It’s easy to fine tune with Arduino IDE programming. And the Robot Hand is fast (connected to 6v) and very responsive. Pressure Sensor: Scotch taped these pressure sensors to a hard surface then connected to a voltage bridge using 10K Ohm resistors on an ESP32. Wires: sensors connect well to the female end of standard breadboard jumpers. Search “RandomNerd ESP32 ADC” for programming. Two arduino commands that are very helpful converting the analog signal from sensors to the PWM signal needed for servos are: map(); and constraint(); Robot Hand: Search “RandomNerd ESP32 Servo” for programming instructions. The library referenced - “Sketch > Include Library > Manage Libraries…ServoESP32” controls multiple servos and is very simple to use

Bought this to play around with it and the size It's probably the size of a teenage hand? I don't know. Just got it but haven't had any problems with it. Tested it with a servo motor tester and seemed fine. The hand seems to be of metal and hard plastic. Looking at other robot hands, they either seemed to be of very cheap material and too small or too expensive for me. So this is perfect for me. I might get the other hand in a few weeks just want to test this one out more before I pull the trigger on the other one but so far so good.
