Spacer Robotics
From Construction Sites to the Moon — Building the Future of Physical AI
Spacer Robotics develops next-generation AI robots for construction, with a roadmap that extends from terrestrial job sites to lunar infrastructure. Founded by Lesya Hendrix, former Tesla and Nuro engineer, the company is deploying GRID — an autonomous rebar-tying robot — while building toward semi-humanoid robots and eventually space-ready lunar construction systems.
Petpin AI was launched and showcased at SF Playground, where it quickly became one of the most talked-about startups on the floor.
The Challenge
As a hardware startup building physical AI for construction and space, Spacer Robotics needed to:
- •Communicate a bold vision spanning Earth and Moon
- •Demonstrate real-world applicability of GRID on job sites
- •Stand out among AI and robotics startups at a competitive event
- •Connect with investors who understand deep tech and infrastructure
Our Role
At SF Playground, we created a platform that helped Spacer Robotics:
- •🎤 Pitch their three-generation roadmap to a live VC panel
- •🤖 Showcase GRID's capabilities to builders and investors
- •🤝 Build relationships with construction and space-industry contacts
- •📣 Generate momentum for their 2026 deployment and 2033 lunar vision
The Experience
The Impact
Spacer Robotics' presence at the event delivered tangible outcomes:
Petpin AI left the event with meaningful connections and momentum — not just exposure.
- •🚀 Strong investor interest in their construction-to-space thesis
- •🏗️ Connections with construction and infrastructure partners
- •📈 Increased visibility for GRID and their 2026 deployment timeline
- •💬 Recognition as a standout in the physical AI and robotics space
