“The Axis Robot is an educational project for learning programming using the Arduino IDE.
This is my make of Robot Axis V1 by Axioma Robotics and published on Thingiverse. I am still working on the software for this project. The hardware side is complete and since Axioma Robotics has designed this project as an educational project for software development, I decided to publish this anyway in case anyone wants to start building this variant.
Wheel motors & Thigh servos
I used all metal gear 6V motors. I had to redesign the wheels to provide a tight fit on the motor shaft. It also allows for a M3 screw to fix the wheel to the shaft. Due to the tightness of the hub on the motor shaft, I found that the screws were unnecessary. The wheels are designed to take a 100m OD, 6mm CS O-ring as tires. All the parts were sourced from Ali-Express.
I disassembled the motors and spray painted the shells, wheels and 6-legged servo horns with gloss red paint.
When I screwed the thigh to the servo using the 6-legged servo horn, I found the leg to be quite loose (A lot of lateral play). To fix this the 3D printed shims can be used to pack out the servo horn to get a tight fit. I made 5 different pairs of shims ranging in thickness from 1.0mm to 1.8mm. Just pick the best pair that gives a tight fit.”
