I am excited to see what you come up with I don’t have access to many of our engineers right now (during the holiday), but can certainly ask around and get back to you when I hear back. The bots are going to work with your bluetooth hardware in the same way that any other bluetooth device would, so the best bluetooth hardware, in general, is also going to be what works best with Sphero bots The bots we manufactured a few years ago are going to use normal bluetooth and our newer bots are going to use BLE (bluetooth low energy). Knowing which your bot uses will likely be the only thing you’ll need to consider when looking at new hardware (It looks like you have a BOLT? That would use BLE ).
Additionally, if you haven’t already secured a bluetooth device for each of the bots you’ll need to control, I would be happy to chat through ideas of how/where to gather such things (you don’t have to use the same type of device to control each bot, so you can have a myriad of tablets, phones and laptops; whatever you can gather!).
Hope you’re having fun!!
