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

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.

The media could not be loaded. 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

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

The media could not be loaded. 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.

Good hand for messing around with. Build quality was good, servos are fast. It’s the size of a kids hand. Not a small child but maybe a tween. Also I have not tried to make it pick things up but it might not do well with out adding some grip pads. Also the way the fingers close it probably wouldn’t be a great grasp

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.

Great value.

I did a review on the other side hand.My wish is the apposing thumb was moveable.
