Starting this week at one Houston, Texas Dominos location, a robot may deliver your pizza to your home. Customers who place a pre-paid website order can have R2 deliver their pizza. R2 has been cleared as an on-road delivery vehicle. Customers will receive text alerts with updates on R2’s location. Customers will receive a unique PIN to get their pizza when R2 arrives. Punch in the PIN on R2’s touchscreen and the door will open with your pizza.
