In the future, robots will deliver your drinks and perform many other tasks in indoor environments. As this video from Clearpath shows, it is possible to turn a Boxer indoor robot into a beer delivery bot. Boxer is a large robotic platform for industrial applications. It is easily programmable and extensible with third-party plug & play sensors.
Boxer already comes with a front-facing stereo camera and LiDAR, rear ultra-sonic sensors, IMU and wheel encoders. It has a max speed of 4.47 mph.
