ASSEMBLING PARTS!
Okay so,
I assembled parts, like I tried assembling parts in pieces,
Like body to coxa motor then coxa motor horn to femur then femur motor horn to tibia then tibia motor horn to leg and then leg to ground shock sensor.
Like I will try to make a complete assembly but maybe my laptop won’t be able to handle it.
But still, I will try complete assembly if possible.

A DIFFERENT KIND OF SHOCK ABSORBER AND REBUILD FEMUR PARTS!
Okay, so I made a very simple design for the new shock absorber, but I will just be using tpu instead of pla, do I guess that I should work.
And rebuild and modified all femur parts as they were all short in length.
And made go through space for servo wires in body and tibia.

MAKING NEW SHOCK ABSORBER AND REPAIRING PARTS!
So, i remade the shock absorber again and after 6 failed variations made another 4 today and repaired few parts and making the new shock absorber took a lot of time.

REPAIRING AND UPDATING PARTS.
So, like there were few parts which I made wrong and few needs to be upgraded so I didn’t repaired few parts and ungraded this whole part.

1ST TEST LEG And MISTAKES!
So, i finally got the first test leg 3d printed from a local 3d printing service by my own money.
I order all the parts of a whole single leg and few different different variants for shock absorber but non of them worked.
And also I tried assembling the leg but wasn’t able to as I didn’t had screws for it , and there were few or maybe more then few 😅 mistakes in it ,and some parts need to be improved, so I wrote everything I have to change and also I forgot that I wanted 3-4 exactly same parts in more then 1 quantity so wrote that also, so will now again edit or redesign parts.

FINALL! BODY FOR THE HEXAPOD 2.0 MORE TORQUE LEGS!
So, finally after 3-4 tries body for the mg996r servo with more torque leg version is completed as I wrote in previous devlog i tried to make spider net kind of bottom bed and made windows and x shape windows so that it can have less weight and good strength.

MORE TORQUE LEG BODY DESIGN!
So, made the whole body again and made it at origin this time and now was trying to make the spider web kind of structure for the bottom layer and it’s all so much messed up, but I think I will be able to do it so will try.

😭😭divided into in 1/4th and did a lot of work, made coxa part brackets and made a lot of triangles for the triangular structure like bottom and then later on realised that it’s center is not on origin so it was all waste and will have to made the whole body from scratch again😭😭

MORE TORQUE LEG DESIGN BODY CAD!
So, it’s the body for the more torque leg design, for now it’s the can say the basis structure and then will later on make triangular pockets on walls to reduce weight and weight and remain rigid and will also add holes for screws and supports also.

THE FINAL BODY DESIGN FOR MORE TORQUE LEG HEXAPOD/SPIDER ROBOT 2.0!
So, the first one was too wide then tried making it less wider but then thought there should be more space for wires and maybe air flow also for those converters.
So, in the 3rd one increased a few 2-3centemeters and its all good now and have space for other small things also if needed.
And do we need to record timelapse when we post the ship?

BODY DESIGN!
Came up with this body design, maybe will change it later on if needed for now it can fit battery and converters and drivers, maybe will increase width later on to get flexibility in batter space.

STL FILES.
Made all STL files and did fillet wherever I was able to and realized that I forgot to make screw holes, and all that took more time than expected.

Finally, the more torque leg design is completed now will have to order them and check if everything fits perfectly and will also make the long leg less torque designs.

GROUND SENSOR / SHOCK ABSORBER!
So, finally the ground sensor/shock absorber CAD files are completed it has 6 parts it’s very complex and still have to make some more shock absorber designs with another dimensions and will be checking everything and will also start designing leg parts.

Tibia design fixed again and designing ground sensor and shock absorber!
Okay so I fixed the tibia design as the last one was too curved and also, I will be adding a shock absorber so that the gears won’t break! Till now 20% of the shock absorber’s design is made.

High torque design done!
So was finally able to figure out the designs and made the height torque design, so in this High torque design the femur and tibia are as short as possible so that it gets maximum torque. Now will start CAD and will also make the less torque/long leg design.

Redesigned the part!
Finally redesigned the femur horn to tibia servo part including the servo bottom cover chassis and will have to redesign the femur to coxa part too, and I made this simple mechanism too as I wanted to test something.

Ohhh nooo made a mistake!! Hexapod 2.0!
So, I forgot to measure the bottom wall thickness which will be covering servo and will be having ball bearings and now I will have to redesign the (Femur servo to Coxa horn) part and the new part I was making which will connect Femur horn to Tibia servo. And I deleted all the previous cad files for Hexapod 2.0 as they were all without that bottom wall measurement.

DESIGNING FEMUR HORN TO TIBIA MOTOR PART FOR HEXAPOD 2.O! So, I’m trying to figure out things like how I would connect the motors to each other as due to angle and other things the lengths changes and I’m thinking of making a different type of tibia or maybe a modular tibia. but for now, I will try to complete the femur to tibia motor chassis.

NEW FEMUR MOTOR CHASSIS DESIGN FOR HEXAPOD/SPIDER ROBOT 2.0!
Okay so, I did modifications in the femur motor chassis design as I forgot to make holes for servo mounting screws so had to change both upper parts chassis designs. Maybe I’ll change the lower chassis design later if I can find a better alternative for the ball bearings.

Femur servo chassis first upper part!
This part will hold the horn of the coxa servo and will attach it to the previous part which holds femur motor by using M3 screws.

LEG FOR BIG HEXAPOD/SPIDER ROBOT!
So, I made parts for coxa servo and femur servo, the upper one will attach coxa servo to body, and the lower one will attach femur servo to coxa servo horn. and this time I will be using ID=8mm, OD=22mm, W=7 mm ball bearings.

HEXAPOD/SPIDER ROBOT 2.0!
So, this will be the larger version of the hexapod/spider robot, in this version I will be using mg996r motors instead of mg90s motors. I noted all dimensions of the servo and the circular horn and now will start making the leg designs.
