Flywheel AI vs Built Robotics
Two ways to add autonomy to heavy equipment. Flywheel AI retrofits existing excavators for remote operation and uses the teleoperation data to train autonomous policies. Built Robotics sells AI-powered pile-driving robots for utility-scale solar and an Exosystem autonomy upgrade for excavator trenching. Desk research from vendor pages and Flywheel AI's YC profile read Oct 19, 2026; not tested, no winner.

Side by side
| Sheet row | Flywheel AI | Built Robotics |
|---|---|---|
| Category | Remote operation for existing excavators | Autonomous pile driving |
| AI role (our label) | AI-first | AI-first |
| What it does | Converts existing excavators for remote operation. Its YC profile says the retrofit lets contractors run machines remotely for safety and productivity and that the robotics data collected is used to train autonomous policies. The company site (read Oct 18, 2026) is a single short page: remotely operate excavators, remotely control multiple machines or sites, increased safety and predictable costs, and monitoring of operator performance, with a contact form and demo booking. It gives no list of supported machines and no technical details. Y Combinator batch: Summer 2025 (YC company profile). Re-checked Oct 19, 2026: the site is unchanged. The YC launch post on its profile adds that the retrofit is machine-agnostic for hydraulic equipment, installs in a few hours and does not block manual operation; that its low-latency teleoperation platform can turn machines on and off remotely, lets a supervisor take over at any time and runs from a laptop and joysticks; and that it uses operating data to train models for tasks such as dig and dump, trenching and grading, so one operator could manage more machines (stated as the goal, not a shipped feature). The profile lists a team of 2, founded 2023, in San Francisco. | "Physical AI for construction": AI-powered pile-driving robots for utility-scale solar. The RPD 35 carries up to 224 piles (34,000 lb payload); piles up to 19 ft, W6x7 to W8x28. The RPS 25 guides piles to within 1.0 degree of plumb and 15 mm of design elevation. Fleets can run up to 24 hours a day. Vendor cites 50,000 hours of operation, 40 deployments, an 8-layer safety system, and zero jobsite injuries (vendor claims, not verified). Used in the US and Australia. Re-checked Oct 19, 2026: the homepage figures above are unchanged, and the Solutions page now lists Trenching alongside Solar Piling: the Exosystem, described as an aftermarket autonomy upgrade for mid-size excavators from the leading manufacturers, installs in under a day, is fully reversible and keeps manual operation, with vendor-stated maximum production of 180 feet per hour, 0.1 ft digging accuracy and a 10% maximum grade for solar DC and AC trenching. The technology page names Everest, a cloud command center for monitoring and operating the Exosystem, and says its worker-detection models are trained on 1,000,000+ images (vendor claims). |
| Who it's for | Contractors that run excavators (per its YC profile and site). | Utility-scale solar contractors. |
| Pricing (as publicly stated) | No public prices found (checked Oct 18, 2026; unchanged Oct 19, 2026): the site offers only a contact form and demo booking. Confirm with Flywheel AI. | No public prices found (checked Oct 16, 2026; unchanged Oct 19, 2026): the vendor site has no pricing link in its navigation; builtrobotics.com/pricing redirects to the Solutions page and /plans returns a not-found page.

Where the vendor descriptions differ
- Machines: Flywheel AI's YC launch post says its retrofit is machine-agnostic for hydraulic equipment, installs in a few hours and does not block manual operation; its site says remotely operate excavators and control multiple machines or sites, and lists no supported models. Built Robotics sells the RPD 35 and RPS 25 pile-driving robots (up to 224 piles and a 34,000 lb payload, piles up to 19 ft in W6x7 to W8x28 sections, guided to within 1.0 degree of plumb and 15 mm of design elevation) and the Exosystem, an aftermarket upgrade for mid-size excavators from the leading manufacturers that it says installs in under a day, is fully reversible and keeps manual operation.
- Autonomy today: Flywheel AI describes low-latency remote teleoperation from a laptop and joysticks, remote machine on/off and supervisor takeover at any time; autonomous dig and dump, trenching and grading are described as what its models are being trained to do, so that one operator can manage more machines. Built Robotics describes autonomous robots running in coordinated fleets up to 24 hours a day, an Everest cloud command center to monitor and operate the Exosystem, an 8-layer safety system and worker-detection models trained on 1,000,000+ images (vendor claims).
- Work scope: Flywheel AI names contractors that run excavators, with safety, productivity and operator-performance monitoring as the pitch. Built Robotics names utility-scale solar contractors in the US and Australia, for solar piling and DC and AC trenching (vendor-stated maximum 180 feet per hour, 0.1 ft digging accuracy and 10% maximum grade).
- Company stage: Flywheel AI is a Y Combinator Summer 2025 company; its profile lists a team of 2 and its site is a single page with a contact form and demo booking. Built Robotics cites 50,000 hours of operation, 40 deployments and zero jobsite injuries (vendor claims, not verified).
- Pricing (checked Oct 19, 2026): neither publishes prices. Flywheel AI offers a contact form and demo booking; Built Robotics has no pricing link, and builtrobotics.com/pricing shows the Solutions page. Neither tool has been tested by Means & Methods Lab.

Questions to ask in your review
- Whether Flywheel AI's retrofit works on the excavator models in your fleet, and what connectivity a remote operator needs on site
- Whether Built Robotics offers Exosystem trenching outside utility-scale solar work
- What a pilot or deployment costs for each, and who carries liability for a remotely operated or autonomous machine
- What did you use it for, on what kind of work and project size?
- How long did setup and training take, and who on your team did it?
- What does it cost you in practice, compared with what the sales call said?
