@Chris Hester Spoiler: the Rs You can use the fixed slider next to one of the Rs to delay it a little, and get them unstuck. Spoiler: And B? I won without using B, just one R.
@Chris Hester Spoiler The key is the "bot freezer" draggable attached to the ground next to the bots. In this case, you can use it to separate them. Ooopps, @cimarronline got ahead of me
Strange level. Given your history with using BB (Boogie Bot) in previous levels, my first win was with B, bypassing the two Rs. I imagine my second win will be similar to @cimarronline's because it didn't involve B, just one of the Rs. Thank you for sharing @Super H
Thanks to everyone for their help! I won with just one R (the other fell off the level). Not sure what B was for. I did not use the middle blocks either that slide out.
