Slip Robotics is turning trailer-loading robots into a dock automation layer

Four Hands deployed 15 SlipBots across multiple Austin, Texas facilities and reported trailer loading and unloading time falling from 90 minutes to 10 minutes per trailer. Operators load products directly onto SlipBots without a floor-staging step, and receiving teams unload freight from all four sides after the robots exit the trailer.

By December 2024, Slip had launched commercially and placed hundreds of robots across 25 sites for more than 10 customers, with named customers including John Deere, Nissan, and GE Appliances. Slip also raised a $28 million Series B led by DCVC, with Eve Atlas and Tech Square Ventures participating. Source

SlipBot is built around a simple dock constraint: trailers are still loaded and unloaded through labor-heavy, time-sensitive processes even inside automated facilities. The robot carries 12,000 pounds of freight on a deck with a 204-inch length and 98-inch maximum width. Three SlipBots fit inside a standard trailer for a five-minute load or unload cycle, with a human operator guiding the robot before autonomous alignment and parking.

SlipLift handles heavier freight and lower-volume routes that do not fit the original SlipBot routing pattern. Source
