My kitten has no problem with skills such as 'kcr' and 'kbk', but when I run 'kwk' it falls down quickly. What kind of problem can be considered? Is it a left-right balance problem? By the way, I have no Raspberry Pi on my kitten. Do you have any suggestions for improvement?
You may try moving the battery holder forward or backward to tuned the cat's center of mass.
Raspberry Pi is optional if you have some ideas in improving the cat's intelligence.
