Test assembly of CF leg with new lower design/foot. Everything fits perfectly! Happy with the more rough looks!
Weight data comparison:
Upper:
CF = 219g
7075 = 315g
reduction 43%
Lower:
CF = 185g
7075 = 254g
reduction 37%
Motor mount:
CF = 99g
7075 = 145g
reduction 46%

A very rough first print for half cover. Needed some to touch and visualize IRL before going further with covers. And No I will not use home 3D printed covers. 
I am adding a impact bar.
The new idea with back/front cover is to design around the impact bar. The back cover has an internal plastic structure and a outer molded CF cover. not a fan of the sharp intersection between top/bottom cover.
Continued on back cover. Changed how I let it out on the top cover. A small floating touch where they intersect.
Tonights work. Redesign of mid covers is started. Going for a more clean look with a “easier” shape. Let’s continue tomorrow. 
Back to matte green! 
Prefer the look of this front / back to the “insect” one TBH.
Both very nice. Black is generic and Spot is yellow, but don’t know of any which are blue.
Thanks. The black is actually CF molded top covers with black structure parts. Which is my plan today. if the CF will painted later we shall see.
One blue quad is Jueying mini
Quick and dirty half test cover for shape verification!
Was honestly not aware of Deeprobotics’ dog. It seems to be a collaboration with Huawei? Their videos only seem to date back three months.
Curious - your current focus seems to be the aesthetics, but I don’t recall seeing a video of it actually walking? Been looking forward to seeing that for a while, despite the fact that the project seems to be progressing at lightning speed.
Yeah doing alot of things simultaneously 
You’ve almost trained it to “give paw” / “shake” 
Testing the lower leg speed. Running 24v ATM (quad will run 10s) hitting a peak at around 20rad/s now. Excepting numbers around 40rad/s later on.
Not much happening today. Adjusted magnet gap for the encoder to around 1.5-1.7 mm to reduce some current noise. So now they are almost silent
I got a Vectornav VN-100 for the robot
And the last chain just arrived
The new power supply is ready for hopefully a first “test” stand this weekend to get some data to analys.
Tonights work patched the #UPboard #UPXtreme stock kernel 5.4 with RT-PREEMPT.
Stock UP! Kernel
