Notes on the mechanical design of the Sojourner rover
here's an interesting still from gearskeptics video

yes, thank you, I have been stealing screengrabs from his video and corresponding with him by email.
I suggest you edit your prior message to remove your email to reduce the spam you receive, and continue the disucussion on the github repo I opened here: https://github.com/nraynaud/sojourner/blob/main/README.md .
I'll try to do a data dump in the repo today.

Thank you much, I am able to read the files now.
I've been interested in building my own Sojourner-alike, and don't mind cheating with the electronics (I don't intend to build an 8085 based brain but a similar or slightly more powerful microcontroller will do. I've also modeled a modern inexpensive 16mm geared brushed motor (16GA25) which can sometimes be found geared down to 10RPM at 6 or 12 volt. It is slightly smaller than a RE-16 from the looks of it, perhaps it could be disguised as one with a housing. An encoder would need to be fitted for proper odometry or servo control. I am fond of as5600 absolute encoders.
