LewanSoul Robot Hand Five Fingers Solely Movement Bionic Robot Mechanical Arm DIY, Left Hand

Size smaller than expected.

A little bit expensive. I can build one on my own, but rather save time, and is expensive. I got it work with PCA9685, on PIC18F4550.

So far it's the best robotic hand I found so far saving me tons of time vs 3d printing one. The kit was fully assembled and it came with motors too. The kit didn't come with any source code or programs. Though one can find that on the internet if you have the the time to figure out how to program servo motors. I was able to move all of the fingers so far so the kit was well made with great parts and well worth it too! Make sure you order the correct hands as there different listings for each I did receive both a Left and Right and and that's what I ordered.

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.

I couldn't find this until recently here. Sellers elsewhere had it more expensive and Idk them. I'm glad LewanSoul put this available here. The hand is exactly what I needed to test some structure and study the robotic capability compared to a human hand and let me say it is useful and has helped me out in that. I've bought a few hands for the purpose of studying the limitations with this which is why u might see certain unexpected categories in my reviews... but anyways this hand is more than a desk display. Powered using the same servo control by the same company and a 9v battery after hooking up the servos to the controller. This was slight puzzling as my servos were not labeled on the Right Hand either way no problem. I managed to output if I remember 8.5v from the battery able to move all the servos with good speed at once. Not sure if that's good since servos use mostly 4.7v and the control too... but I'm new to this either way I haven't seen issues. If u supply less than 4.5v I notice yeah you lose power to 1 servo and moving more than one isn't gonna happen. The hand has no real grip power just tender strength I guess. Some modifications may help with this. The servos are all functional on mine no issues but note it is not as articulated as the human hand and fingers cannot separate or close in together (side to side whatever that's called). It's as u see very simple. Even though I'm way in over my head with my project, I know there are people out there who have a ton of experience with stuff like this and finding a hand that works is nice. If u got some money to spend you won't regret buying this since it's really setting the canvas up for you. Note: The 9v battery was adjusted with a buck power down converter. It is possible to overcharge the hand temporary and see the speed but yeah, don't expect it not to fry your servos like that and ruin it. It's better to adjust as needed since the power should be to the specifications to be safe. I think safe is 4.5v to 4.7v.

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
