Holidays in 2020 are a little different. My family is spread out around the country, and due to the pandemic we're unable to gather together. To include other family members in our holiday celebrations, I built a telepresence robot from a Raspberry Pi, a Snap Circuits rover, and an iPad.

Love it! Due to a back condition, a friend had to work remotely for a year, and her office got her one of those commercial ipad based telepresence robots - she loved it and really helped her feel in the office.
Great you've been able to get the vast majority of the benefits so cheaply!

Great suggestion. The extra sensors in particular would be a welcome improvement. I had the Snap Circuits rover on hand already, so my total outlay was about $20.
A big question when building the base is whether it's heavy/wide enough to be stable. Mounting the tablet up high is great for interaction, but results in a high center of gravity and a long moment arm conspiring to cause instability. From the specs it looks like the iRobot might be both heavier and wider than the Snap Circuits rover, so it might be a great choice.

Neat project. I'm a big fan of Snap Circuits so this was a cool project to see. I'm thinking of doing something similar with Sphero RVR. My biggest worry is charging the base. The ideal solution seems like a roomba (with charging base).

Another commenter referenced a programmable roomba from iRobot - see above. I agree that might be ideal. The RVR might not be stable enough to haul around a tablet sitting atop what amounts to a big lever, but a camera mounted (low) on an RVR could be a lot of fun.

IMHO I feel like adding a periscope would keep your pricey phone or tablet closer to the ground and less likely to be destroyed if the platform tips over.

Part of the goal was to have a large image of the remote person’s face at a height that’s comfortable for interaction and conversation, which necessitates a screen mounted fairly high up.
To your point, I bet a picoprojector mounted down low could be made to project onto a lightweight screen in place of the tablet.
(The tablet arrangement worked well enough in practice, and we used a tablet that had already suffered child-related damage)

Its not much more at $200 and gets you all the sensors on a roomba (bump, cliff, etc), return to dock, charging, virtual walls, etc.
