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.

FINAL PART of femur motor chassis! This is the final part which we need for the femur motor chassis, now after this tibia and coxa.

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.

PLAYING GAME ON TRANSMITTER!
Was just checking the oled and switch and joystick so thought of playing the classic snake game. Should I put a mini speaker/buzzer so that it makes a beep sound whenever any option is selected on the display?

HEXAPOD/SPIDER ROBOT FEMUR MOTOR PART! Made the lower piece of the femur motor chassis, each leg part is in 2-3 pieces. this one holds the motor and ball bearing hold bracket for coxa motor piece and a socket to fit ball bearing for tibia motor piece.

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 WALKING!!
Okay so it is walking but it’s trying to break its motors. Reducing ground clearance will help as motors won’t have to work more. So will do that but as I have started working on HEXAPOD/SPIDER ROBOT 2.O! (https://stardance.hackclub.com/projects/22328) maybe I will be giving less time to this one but still I will try to make it walk properly and then I will have to control it using my transmitter (https://stardance.hackclub.com/projects/22304/devlogs/22662)

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.

HEXAPOD/SPIDER ROBOT TRYING TO WALK!
So, it did tried walking but broke 3-4 servos, so will have to change the angle between femur and coxa and will have to replace broken motors. And can someone tell me in comments how to post video on devlog without shipping it as I haven’t completed the coding it yet, but it does walk a bit.

CODING THE HEXAPOD/SPIDER ROBOT!
So, I tried coding it to make it walk firstly, and of course it’s not working, so will try again, will try to figure out angles of all three joints and each leg.

FINALLY HEXAPOD/SPIDER ROBOT COMPLETE! The hexapod and transmitter are fully assembled now just have to add receiver system to hexapod and will have to program both hexapod and transmitter.

LEGS OF HEXAPOD/SPIDER ROBOT!
Finally got the legs of hexapod/spider robot, then started assembling them but the 1.7 mm holes for 2mm screws were too much tight so, manually had to increase holes size, then soldered some broken servo wires and changed internal gears of some servos and was finally able to complete all 6 legs!

HEXAPOD/SPIDER ROBOT TRANSMITTER WIRRING FINALLY COMPLETED!
Finally, the transmitter wiring is completed, now will have to code it and setup the receiver system for hexapod.

POWERING THE TRANSMITTER FOR THE HEXAPOD/SPIDER ROBOT AND ADDING SCREEN!
So, I used 2X 3.7v 18650 cells in parallel and then connected to step-up module to get 5v for ESP32 and NFR adapter, and I’m using TP4056 for charging and a battery level indicator and I still have to do the wiring of 0.96inch OLED display and the 3 push buttons.

TRANSMITTER FOR THE HEXAPOD/SPIDER ROBOT!!
So, I did basic wiring of the main transmitter for the hexapod/spider robot. I used ESP32 and 2x joystick modules and NRF24L01 adapter and NR2401 PA+LNA module, AND ADDAD A STEP-UP MODULE TO GIVE 5V POWER SUPPLLY TO ESP32 AS I WILL BE USING 2X 18650 cells to power it.

TRANSMITTER FOR HEXAPOD/SPIDER ROBOT!!
So, as I’m waiting for the leg chassis, so I thought to make a transmitter for the hexapod/spider robot, I used ESP32 DEVKIT V1 CORE 3.X as I only have that micro controller except A4RDUINO R4 MINIMA but as it’s been used for robot, so I used esp32. And I still have to make the connections of ESP32 and joystick and NRF24LD1 adapter.

LAST PEICE OF HEXAPOD/SPIDER ROBOT CHASSIS!
So, I made the last piece of hexapod/spider robot this is the tibia part of leg, and this is the final chassis we need to complete the whole hexapod/spider robot chassis. The tibia leg is curved so it won’t touch the femur and get more range of motion and has slot for wire of servo and support rod behind. now will get all the leg parts 3D printed from online 3D printing services.

MAKIING THE FEMUR PART OF HEXAPOD/SPIIDER ROBOT LEG!
So, I made the femur part of the hexapod/spider robot. It has two servo horn sockets so that we can put the hip servo and tibia servo horn in the sockets and the three holes in front are for adding the support which I made previously and at the back there’s a slot for the tibia motor wire and two holes so that it can hold the coxa and tibia chassis supports.
