With a height of 1830 mm and weight of 101 kg, HRP-5P is the successor to both HRP-4 and HRP-2Kai. Both legs have 6 DoF each, both arms have 9 DoF each, and both hands have 1 DoF each. The neck has 2 DoF and the waist has 3 DoF bringing the total to 37 DoF. Waist DoF’s have two motors for each joint, while knee pitch has three motors per joint. Each arm of HRP-5P, extended horizontally, can carry a weight of 2.9 kg, compared to 1.3 kg for the HRP-2Kai and 0.9 kg for HRP-4. This increase in strength is due to better lubrication for the harmonic gears, better cooling system, and higher power motors. HRP-5P uses ELMO Gold Twitters for motor controllers and EtherCAT for its fieldbus.
“Furthermore, HRP-5P inherits the technologies of HRP series and utilizes patented technology of Honda Motor Co., Ltd.”
NOTE: I haven’t been able to figure out what technology that HRP-5P is using from Honda.

Humanoid Robot HRP-5P: An Electrically Actuated Humanoid Robot With High-Power and Wide-Range Joints HRP-5P Toward robust whole-body motion control for locomotion in unstructured environments
HRP-5P was on static display at the World Robot Summit in Tokyo on October 18, 2018.
On May 23rd, 2019 a video (linked above) was released by a researcher showing HRP-5P doing complex manipulation. More footage of hardware testing was released in 2021. In 2022 simulation of reinforcement learned gaits was posted to the CNRS-AIST JRL YouTube channel and later results were shown on hardware.
