Coraopolis-based Seegrid Corp., a maker of autonomous mobile robots for pallet material handling, closed a $50M Series D investment round, funded by existing investors Giant Eagle and G2 Venture Partners, along with smaller investments from other existing shareholders.

The investment is intended to allow Seegrid to accelerate its fast-growing autonomous lift truck business.

"We are thrilled to have secured this additional funding from our investors," Seegrid CEO Joe Pajer said in a statement. "It enables us to drive our innovative AMR technology and solutions into the market faster, delivering even more value to our customers sooner."
