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

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.

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.

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.

No problems operating this device! Simple plug and play! I connected it to servo control from Amazon and it worked!! Fast delivery too

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.
