Building a giant robotic hand for my giant rideable robot wasn't on my bingo card for this year and yet here I am.
In this video I'm building a giant robotic hand that will potentially be a part of my giant rideable robot build so If you're interested on me giving it a go you know what to do ;)
This is definitely the first iteration of this 3D printed robotic hand as once finished I got lots of ideas that will make it 10 times better and honestly, does one ever finish building his giant rideable robot?
As always leave your thoughts down below so I know what todo.

When Ivan single-HANDedly created a shortage on red PLA, he turns to white😂 Nice build! I'm excited for the rest of this project! I think Mirandabot would be a fitting name.

Getting into mecha construction? Fun. To reduce the servo count, you might consider a single pull strap for the entire finger, then springs to push it back open, and then pressure sensors under the finger tips for limiting.

Nice project! But for the servo's, maybe the pca9685 is a nice option to consider in the future. A single board can drive 16 servo's via I2C without any issues, and you can chain them to drive up to 992 servo's or other PWM hardware over a single connection!

I think it needs stronger motors with lower gear reduction to be more effective at grabbing things. Those servos have little 5v motors with high gear reduction. Great vid! Keep it up!

@ulforcemegamon3094 11 ай бұрын

Yeah , having only 11 and 25kg seems insufficient with something this big, the servos should be 50kg+ and there are some 3d printed gearboxes which he could use for the fingers

@buildingwithlogan 11 ай бұрын

@@ulforcemegamon3094 Yes agreed. Also to add to that, there is a slight belt reduction at each finger joint but the leverage that is lost from the fingers being so big is not helping. I think one larger motor for each finger and then each finger joint is connected in a way would be a better solution than small motors at each joint. I'm studying engineering right now and could calculate the current max leverage at the finger tips if we knew the finger length, pulley diameter, and the belt reduction. I have a feeling Ivan didn't do any math for this lol. (Which I don't blame him tbh)

For a Hexapod project, I once also had the idea to solder a wire to the potentiometers of the servos. As I had 18 servos to control, and I did not want to use 16 ADCs I used some analog multiplexers. This did not work at all. Somehow the analog multiplexer did not have a high enough input resistance in order to decouple the potentiometers from each other and the whole thing worked like a big resistor network and the servos started acting chaotically, as moving one servo also resulted in a resistor change in the other, which they then tried to compensate in the control loop.

Commenting to say that the "good thumbnail" pun made me very happy, (and to feed the KZfaq algorithm and let it know that I'm clearly engaging with this content.) Your sign-off "Now go make something!" is causing me to feel bad about not doing so right away. If only feeling bad about not creating stuff was helpful for getting me to create more and not less... (That said, I have enough projects running in paralell to make it feel like I am at least creating stuff occationally.)

Interesting choice to control every joint with an individually controlled servo. I would have either wired them all to the same signal wire so they moved together or used a sort of tendon to pull on them all at the same time. But I've never done a project like this, so good job.

@gdipaolo 11 ай бұрын

If you are thinking to control all the servos of one finger you don't need to use one servo each joint. But by doing it you can archive much more accurate and realistic movements

You are forgetting that fingers can move sideways to a degree as well, and the hand surface flexes to a cup shape so that the tumb and little finger can meet. It's why making a robot hand is hard to get right.

This is really cool and I like the finished look of it. I was wondering if the servos were going to be able to move so much weight and it looks like they soft of can, but the belts aren't helping them any. Would it be too over-built and expensive to switch those out for chains and sprockets? Maybe also some motors or servos with worm gear drives to improve torque? I'm also wondering if instead of a belt or chain you could use a thin steel cable and the motor could be fitted with an oval shaped cam to pull back on the cable. You could add springs to return the fingers, but maybe another cable going the other direction around the cam would work better.. Maybe a spring keeping tension on the motor mount/gearbox assembly. You probably already have a better solution in mind, so I'm curious to see what you come up with!

@conorstewart2214 11 ай бұрын

You should consider using actual servo drivers rather than just the arduino mega. The arduinos, especially with complex code can end up with jitters or unwanted movements on the servos since the arduino servo library is interrupt based and only controlled by software. This could end up with issues as the code gets more complex like reading the positions and implementing feedback. Using hardware timers is the best way to do it and is how servo driver boards do it, you could also get and use a microcontroller with enough hardware timers like some STM32 microcontrollers but you probably want to stick to using arduino. Two options are to use a commonly available servos driver board with 16 outputs, or to use the servo 2040 board from pimoroni which uses an rp2040 to drive the servos since it can use the pio to drive the servos properly. The common servo driver boards have an arduino library that makes them very easy to use and are probably your best choice.

something to possibly consider that would let you simplify wiring, human hands don't have individual joint control of fingers instead, it's just a long tendon connected a muscle in the upper arm you could have a pulley connected to a far more powerful motor hidden in the arm or hand of the mechanism, that way you can get something more powerful, and each joint could bend to fir the form of the object it's holding automatically to a degree also, the movement of the thumb is extremely important for grabbing. It's why people talk about humans having opposable thumbs being so important. Without that 2-axis movement on the base joint, grabbing becomes a logistical nightmare

@alessandrofonseca7796 11 ай бұрын

Its seems you don't need the motor in the finger's joint at the top. Only those in the hand's joint and the middle section. I'd connect the tension belt from the middle section motor to the finger's tip, bypassing that third motor. Just watch how your finger moves!
