2022-07-10 - lemur's bobik

a friend of mine sent me a description of a home-made electronic toy for a child. that in turn reminded me of a Lemur's bobik – pandemic-times project for my son, aimed at learning basics of programming.

to control it, you have to insert a program, by providing a predefined set of actions, similar to programming in logo. available commands are:

• forward
• backward
• turn left
• turn right

5th button is “start”, that begins program execution.

robot was built during 1st COVID-19 lockdown in PL, so i tried to use only parts that i had available (including unipolar stepper motors from an old printer :D). this ended up in a funny mixture of SMD and THT components. there is a TODO list for addressing some of the shortcomings of the current design. my son is now also 2 years older, so i guess it would be even more fun for him now. :)
