However, most of our distributors order the kits without the wall pack, as our wall packs are made for use in USA and would require an adapter for international use.
My mistake. I didn’t know those sold in the USA came with the wall pack.
If you don’t have a wall pack, it is very helpful to have one because when developing code for your bot, it’s nice to have a steady power source and not having to worry about a battery pack going dead, and then having to wait for it to recharge before you can continue on with development.
The wrist rotate is nice to have but not required. I would want one if it were me.
At the end I’ve purchase a wall pack and wrist rotate!!!
I’ve started to building my ARM. In the correct section of the forum I will post the photo of the all building step!
