This is a completely re-designed version of my 6 axis robotic arm. It is a bit more compact, uses fewer parts, is faster, stronger, more rigid, and is much more precise than my previous versions. This was made possible with many new parts released by Lego since my last submission. Since Lego has discontinued support and sale of the Robot Inventor set, I have switched software to use PyBricks.
Remote Control Here is a video showing the robotic arm being controlled by a 6 axis remote control.
Modular Construction The 6 major pieces of the robotic arm (base, bearing, shoulder, humerus, elbow, and wrist) easily come apart. Two to eight pins hold each piece together. With this exploded view, you can see a bit more of the detail how this is designed. There is a big emphasis on making rigid structures and robust gear trains. It may seem over-engineered but every time I found a way to add more cross bracing and make it more rigid, it got more precise in its movements. Lego is quite flexible under strain which means you need significant structure to counteract that.
Gearing There are over 100 gears in the model. Wherever possible, I added redundant gear trains to both reduce the stress on the gears and axles and reduce backlash. With 2 or more gear trains, you can shift one of them 1 or 2 teeth and "pre-tension" them, reducing backlash to almost zero. In axes 4, 5, and 6 plus the gripper, it is geared up leaving the motor and geared down as close to the load as possible. Making the long runs be higher speed and lower torque reduces slop. Those longer axles are less likely to twist with lower torque.
This shows the gear reduction at the end of the gear trains for axes 5, 6, and the gripper.
Axis 1 (the bottom rotation axis) is interesting because the motor is in the shoulder but the gears are in the base. This allowed a more compact design while still having room to have 4 gears drive the turntable.
Axis 2 (the main tilt axis is also seen in this render. I needed 8 gears driving the turntables in this axis to reduce the stress on the axles. 2 motors are needed there to generate enough power to move that axis at a reasonable speed.
3D Printed Part There is one 3D printed part needed to build this model. It allows sending 3 functions through the center of a 60T turntable. The STL file for the part is uploaded to the site. This part was designed by Efferman.
Here you can see how the 3d printed part fits in to the gearing. With this part, we can transfer axes 5 and 6 as well as the gripper control through the turntable.
Calibration When the robotic arm starts up, it needs to calibrate and find the zero point for each axis. This video shows that. It does several steps.
Use the tilt sensor on the arm hub to point the arm straight up
Align the two motors axis 2
Calibrate axis 1 using the down facing color sensor
Calibrate axis 3 by tilting up till it hits the stop
Center axis 5 by running it until it stops
Calibrate axis 4 using the color sensor on the elbow
Calibrate axis 5 by finding both stops
Calibrate axis 6 by using the front facing color sensor on the shoulder.
Calibrate the gripper by running into the stop
Wire Routing
The rendered images don't show the wires. Here are some photographs to show that.
I updated the Studio file to v2. This fixes some mistakes where some parts were omitted. I also updated the wrist to be a bit stronger and cleaner looking. I uploaded the stl file for the 3d printed part and improved the description a bit.
