If you want to implement field-oriented control (instead of robot-oriented), it works pretty well with just a gyro You'll also want to be able to set/alter the angle whenever (by pointing the joystick in the same direction as the robot, and using that as the offset)

[@conorstewart2214]

A good upgrade could be to add position feedback to the servos, most hobby servos can be easily modified to take out the internal potentiometer voltage that you can then read with a microcontroller so then you can write your code to be aware of the legs actual position. This would let you not use hard coded delays or speeds and instead rely on when the motors reach their set position. That should theoretically allow you to get the fastest walking speed possible and the legs can adapt to different loads and speeds, so if you change the mass of a leg or the walking surface, etc, the robot can tell that the legs are moving slower and compensate for that. It would also allow it to tell if a servo breaks or isn’t behaving right or just tell when the leg is stuck or has hit something. Another thing you could add is an IMU, this way the robot can tell its orientation in its environment, it could tell the angle of the body and allow it to adapt to different slopes and keep the body perfectly level. It would also be good for attack mode since the robot can tell if it is stable or not, or which way it is falling and can compensate. You can get decent IMUs very cheap now so is definitely something worth adding. If your IMU has a magnetometer then the robot can tell its compass heading so then you could have the controller move it relative to the earths magnetic field rather than its forward direction, so no matter what way it is facing all its motion is relative to a certain direction.

[@AecertRobotics]

Thanks for the suggestions! 100% agree. Knowing where the legs are instead of guessing would be invaluable. For this current project though, I believe its out of scope unfortunately. Assuming I could get 18 additional analog inputs (mega only has 16), im not sure the mega can handle reading them every loop without slowing down too much. And even if it could, i want to keep this specific project as simple as possible and to be frank im not sure the added assembly complexity would be worth it. For the more advanced version that i want to do though, i will be doing this. an IMU on the other hand i will be adding! making the hexapod move relative to the controller is something im really looking forward to (in addition to be able to stay level, ofcourse)

[@conorstewart2214]

@@AecertRobotics an analogue multiplexer is a good way to get extra analogue inputs, it just switches between them. You could also use a separate smaller microcontroller, like an Arduino nano just to handle reading the analogue values.

[@Brandon-w3o]

Awesome project! Can't wait to see more!

[@olafmarzocchi6194]

You could use bi-gait for normal and high speed motion, and automatically switch to the other "one leg" gaits when more pulling forward or carrying power (assuming attachments like can holders) is needed.

[@AecertRobotics]

I dont have any way to sense payload weight, but the user could easily change the gaits based on whats needed

[@olafmarzocchi6194]

One option would be to ad a current sensor on one servo, another one to conpare planned motion and actual motion using an accelerometer: if there's a discrepancy, maybe the maximum pulling force has been reached already.

[@tornado3007]

its a realy cool project. keep it up

[@TheItamarp]

Really awesome project! It could be really interesting if you added knobs or sliders to the remote control to tweak the gait parameters on the fly.

Those servos are a bit slow for my taste, but that info would be really nice to have. I know I can mod my current servos to read the potentiometers position, but for this project specifically I think I'll leave it as is tbh.

[@satyananda4389]

Cool sir, your robot has a smooth and stable gait🤩. I'm also building a hexapod using Dynamixel Servo from scratch. I have got formula for Inverse Kinematic and also leg trajectory using Cubic Bezier Curve (with 4 control points). I want to know what the gait formula/concept is (especially for the Tripod Gait) to determine at what point the three leg sholud starts to swing while the other three leg is pushing. So that the robot body can be stable when walking (no dragging feet when walking) like what your robot is doing. And also how do you set the percentage of time when the leg swings compared to pushing?. Does it mean that you set it by determining the ratio of the number of trajectory points for swinging and pushing? I need your help 😁, and also if you can provide an example of arduino code or other reference regarding the thing I'm asking about, I will be very helpful. Thanks😄

[@sripruthiwi3435]

[@PeterKuemmerli]

Hi Aeceret Robotics, thanks for fast reply. If you release your codebase, then i will try to integrate some serial servos with feedback loop. It may be helpful to have informaton like torque and position, when we talk about climbing obstacles with a Hexapod. But you are right, those servos are not the fastest, but at least they have a metal gear and quite a high torque. Looking forwart to your self-built-kit, with best regards, Peter.

I worked with Arduino a long time ago, and I know it would be really hard, but I just can't stop thinking if it would be possible to integrate some inverse kinematics here. Analyzing ground position and its texture, making legs move over and avoid obstacles without changing hexa's trajectory, climbing with horizon lock would look cool if you place a camera on it... my god you don't know how I want to have it on me to try to program it around, even if it means making a computing server on my PC if Arduino fails to handle it, but there is no way I would have time and money to built one myself. Don't have 3d printer, which means I would need to order prints; only one spare Arduino, and a couple of servos. Now thinking about it... I will try my best to find some time to invest into this

[@paradiselost9946]

the idea of ground lock with a camera has sort of lurked in my head for a while. i think it requires two, vertically oriented cameras. maybe three...(mantis have 3 central eyes right?) think of how our binocular vision works. our brain does some nifty calculations and triangulates an objects distance from the relative angles required to make those objects overlap and achieve maximum resolution. on ONE PLANE. the horizontal. we are really good at judging distances apart on a horizontal plane, as it is simply triangulation. but are woeful at heights, we have no reference other than experience.... ever watched someone drop a tree? i find it fun to place bets. usually right because i dont follow my instincts but actually try and visualise the arc of the fall. vertically oriented eyes would give us great vertical or height assessment, with woeful horizontal... (always sort of wondered about evolution and if there would be a need for that feature... then again, wtf do flounders and flatfish think of the world as one eye decides it belongs on the other side of their head?? the things that keep one up at night, lol...{edit. i just contemplated the tuatara, with its "third eye"... maybe nature decided such a feature wasnt worth the effort?}) three should be the nice happy ground. gunna be some nasty independent recognition algorithms going on in each camera, with the trig required to figure out where things are. but seems possible.

[@isaackannianen3446]

Not a huge coding expert here but in order to fix your confusion with the orientation of the hexapod while crabbing and turning, may I suggest a sort of field-oriented control? You could add a gyro and track the direction the bot is facing, and have your joystick forward always move the bot forward, backwards joystick always move the bot backwards, etc. this way it is much easier to control the hexapod no matter which way it is facing.

[@AecertRobotics]

So I love the idea, but i think it would still be kinda weird. Like once you start it up, forward is locked to a single direction? The dream is to have forward always be the direction the controller is facing, but honestly i just need to get better at driving 😆 I have the acceleration really low right now to make animations smoother, but that makes it more difficult to steer. tightening that up a bit may help in the short term.

[@grahamnash6701]

[@whyme6742]

Great progress. Does your code switch between the different walking modes automatically depending on the input speed or is it selected manually?

[@AecertRobotics]

Currently I press a button to cycle through the different walk cycles. You can see that in action here! kzbin.info/www/bejne/rWTUkGeVYr97gJY

[@Personnenenparle]

Love it! Im curious how you did the ground contact percentage. Did you just changed the speed for the 2 curves? Also, for smoothing the movements, you could consider logistic equations. Like ln(1/(1+e^-x)). You can get nice transitions and directions with constant speeds. Also, for the arc formed by a step, it usually looks more like the cross section of a wing than an half circle, and i think parametric equations of that would give you way more control!

[@AecertRobotics]

So the walk cycle is made from 2 bezier curves, one for pushing on the ground, and one for lifting. The walk cycle time goes from 0 to 1. Lets say the ground contact percentage, or the push percentage, is 66%. When the walk cycle time is less than 0.66, i generate a point from the pushing curve based where the cycle time is. If its greater than 0.66, i generate a point from the lifting curve. This percentage can be easily changed, and by doing so will change the amount of time the cycle will be pushing or lifting. Hmmm, i can definitely make different shapes with bezier curves other than half circles, ill have to experiment!

[@Ohlukei]

well, any remote controlled toy moves according to where its forward heading. anyway, would'nt it be easier to just make it learn how to walk even on uneven terrain via a. i.?

WOW, that is great... I my self have been working on a hexapod and I also have struggled alot with the timings... Do you plan on sharing the code?

[@AecertRobotics]

Thank you!! Yeah it can be difficult to get it right. Email me and I'll send you the code

[@PerilousPaddy]

Has anyone suggested jumping forward mode yet?

[@darrylibanez4366]

Maybe you can share the codes link here ....

Hi, this is really good. Do you plan to release the files? I would love to make one.

[@AecertRobotics]

I do! You will 100% be able to build your own 🙂

[@S00rabh]

​@@AecertRobotics Thanks man. appreciated, You can also try PS2 controller instead of building a new one.

@@AecertRobotics when do you planting to do a release ? Im started already to worm up printer :)

[@ediposantos6574]

Do you use automated tests in your code? is the best way to change working code without breaking it.

[@AecertRobotics]

I probably should but I dont 😂

[@ediposantos6574]

@@AecertRobotics It seems that will add a lot of work to create tests, but in the long term it removes a lot of work. Not just for refactoring, but for creating new features, create the test first

[@Cornusse]

It's not debugging, it's adding the "dance mod" :)

[@AecertRobotics]

Ikr 😄 Ill need to add it back as a feature 😂

[@Cornusse]

@@AecertRobotics yeees ! Bring it back, and add the Crabe Rave dance 😂

Stop staring like that into my eyes

Where could I learn this?

[@chrismooney5789]

Climbing gate would be cool, to make it over obstacles. Staircase gate to climb stairs? Lol
