There doesn’t seem to be a great way to attach QTR sensors to the Romi platform, am I missing something? It would be awesome if there was a ready made bracket of some sort to connect it on the front. I like the QTR sensors from the TI Romi, but it doesn’t seem like there is a good way to connect those either. I’m trying to put together a inexpensive (less than $50)maze solving platform for use in the classroom. Thoughts?
