San Francisco, CA – Sept. 11, 2025 – Spacer Robotics, a startup developing next-generation AI robots for
construction and beyond, announced its first product today. GRID, an autonomous rebar-tying robot
designed to tackle one of the most physically demanding and repetitive tasks on construction sites.
After months of development in stealth, GRID will make its public debut at Spacer Robotics’ Out of Stealth
Launch Event on September 11, 2025, at the company’s San Francisco headquarters.
Rebar tying represents the perfect entry point for Spacer Robotics. It is fundamental, required in nearly
every reinforced concrete structure. The global market for automatic rebar tying machines is projected to
more than double, growing from $1.18 billion in 2023 to $2.5 billion by 2032. At the same time, concrete
formwork—especially rebar work—carries one of the highest rates of musculoskeletal injuries among
construction trades (CPWR).
"GRID was built to take on one of construction’s toughest, most repetitive tasks," said Lesya Hendrix, CEO
of Spacer Robotics. "By automating rebar tying, we’re improving efficiency and worker safety while laying
the foundation for the next generation of autonomous construction robots. This is just the beginning - our
long-term vision is to take these technologies beyond Earth and build on the Moon."
GRID automates rebar tying with speed, precision, and enhanced safety, integrating advanced
technologies such as sensor fusion, SLAM, and LiDAR. Its features include universal rebar compatibility,
an RGB camera with smart sensors, 14-hour battery life with standard outlet recharging, and auto-feeding
wire reels that track usage and tally ties completed.
Founded by industry veteran - Lesya Hendrix - whose background spans Tesla, Scania, and Nuro, Spacer
Robotics is committed to advancing human progress through AI-powered robotics. The company’s mission
is to transform construction today while laying the foundation for autonomous infrastructure development
on Earth and beyond.
