I have a 6 months old daughter and she loves our iRobot Roomba 980. We’re vacuuming just for fun with some toys sticked to it. Weird activity, I know, but those who have a child know - you’re going to do whatever keeps your child happy.
And here’s the idea I have - build a nanny bot to amuse my daughter:
- bot should be able to find her,
- bot should be able to play a sound (or do whatever to make her happy),
- bot should be able to follow the road on her Vibrant Village play mat, turn around when it reaches the end, etc.
- when she starts crawling, play with her, move a bit away from her, wait till she moves closer, move a bit away from her,
- when she stops crawling, do whatever to catch her attention and to force her to crawling again,
Bill of materials
This part will be updated when l buy a new part. I’ll try to source all required parts from the Amazon, Pimoroni, …
Here’s the bill of materials for the Nvidia JetBot.
Don’t buy it now, because some parts wont be used. I have to test them and who knows how this will end. Wait till the project will be finished.

Look and feel
I personally like how the JetBot looks like …
… but I’m afraid that my daughter wont like it. I’m going to build & paint a nice balsa wood body. I already have the chassis 3D printed …
… and I build everything on top of it.
- Chassis 3D printed
- Working Jetson Nano on my desk
- Play mat at home
P.S. Buy this play mat even for yourself. I usually fall asleep on it when taking care of my daughter. This soft foam …
I live in the Czech Republic and sourcing all required parts from abroad (so you can buy them as well) will take some time. Usually days, a week or two sometimes, be patient. My goal is to build this bot as soon as possible.
I’m at the same beginning. As a first thing, I’m going to build manually controlled moving part (wheels, motors, …).
Stay tuned! And if you have some ideas for this nanny bot, feel free to share them!
