Overview
RSP-01 was Ryman Sat Project's second satellite. It was a 1U CubeSat weighing around 1.3 kg, and was equipped with an arm that could extend up to 10 cm.{{cite news |date=February 18, 2021 |title=宇宙愛好者らのリーマンサット、ＩＳＳに向け超小型衛星打ち上げへ |url=https://www.sankeibiz.jp/business/news/210218/bsm2102181009016-n1.htm |language=ja |newspaper=Sankei Shimbun |accessdate=2021-02-21}} The CubeSat had three transceivers.

Mission
RSP-01's main mission was to extend an arm carrying a camera, and photograph RSP-01 with the Earth in the background, taking selfies. The arm had a pantograph design to allow contraction after being extended.
Additionally, RSP-01 conducted image recognition by machine learning, and also had a chat function. The CubeSat used its reaction wheel to demonstrate attitude control.
