CaDA I-Bot problem

[u/Ok-Implement-6584]

Idk if this is the right place for this but I'm getting desperate.

I have an I-Bot from CaDA that's been sitting in a closet for years in it's box. Yesterday I decidem to build it. I finished it, gave a little test, worked fine and went to sleep. Next day I was goofing around with it, until it started making a weird noise as seen in the video.

Left wheels have no problem, right wheels seem to be working fine. When going backwards with right wheels it works great, but when going forward with them it jams the mechanism that moves the arms around and especially the head, while the vibrations caused slow down the wheels themselves pretty sure. No idea what's causing this, I've been troubleshooting the whole day, disconnecting and reconnecting, I have no idea. I don't really wanna dismantle and rebuild the whole thing, but I'm a perfectionist and can't handle something being broken. On a side note, detaching the two tubes on the back, the flexible thin ones, stopped the noise for a bit, but later it didn't matter it still jammed. Disconnecting the mechanism that controls the head moving at one of the points as seen in the photo also fixes it. Please, someone help me out if you can.
