Robotics is no longer just a narrow factory-automation niche. It is becoming a broader automation stack that spans consumer devices, warehouse fulfillment, collaborative robots, mobile robots, and autonomous delivery, with demand supported by labor scarcity, wage inflation, reshoring, and the need for higher throughput with fewer errors. That backdrop matters for investors because robotics adoption still looks early relative to the size of the workflows it can automate across logistics, manufacturing, healthcare, retail, and the home.
The most useful way to analyze the space is by separating robot OEMs from enabling component and software providers, and from system integrators or platform operators. Consumer robotics can be more cyclical and exposed to discretionary spending, while industrial cobots and autonomous mobile robots are tied more directly to factory and warehouse automation budgets. Recent results reinforce that this is becoming a real commercial category: Teradyne disclosed $56.5 million of 2025 robotics revenue, Symbotic reported $2.247 billion of 2025 revenue, and Serve Robotics highlighted a 2,000-robot deployed fleet while raising 2026 revenue guidance after acquiring Diligent Robotics.
For this May 2026 list, the goal is to focus on robotics names with identifiable products, measurable revenue traction, and enough financial evidence to judge execution quality rather than just narrative appeal. The ranking below is presented in countdown order, starting with the weakest fit at No. 7 and ending with the best overall investment-quality pick at No. 1.
This screen focuses on US-listed robotics-related stocks with market capitalizations above $500 million, then ranks them primarily by investment quality using our composite grade, profitability, growth, earnings execution, and analyst sentiment. Because this is a countdown, the strongest overall pick appears last at No. 1 rather than first. Where data is limited, the write-up leans on the primary-source business description and the financial metrics available, with an emphasis on distinguishing established commercial robotics businesses from earlier-stage or financially stressed operators.
7. IRBT — iRobot Corporation
Market cap: $0.0B · Quality grade: C · Analyst consensus: Hold (avg target $11.94)
What they do. The company designs and sells consumer home robots, centered on the Roomba family of robot vacuums and vacuum-mop combinations, including the Roomba Combo 10 Max robot + AutoWash Dock. It also generates revenue from accessories, consumables, service plans, and subscription services sold through retailers, distributors, resellers, and direct digital channels.
Why it fits. iRobot remains one of the purest consumer robotics names in public markets, which gives it clear thematic relevance. But this list is ranked by investment quality, and consumer floor-care robotics is the most cyclical corner of the theme, making iRobot much less attractive than warehouse, industrial, and platform-oriented peers.
Numbers that matter. Revenue stands at $1.564987008 billion, but year-over-year revenue growth is negative 24.6% and earnings growth is negative 37.0%. Gross margin is 35.2%, while operating margin is negative 12.06%, even though reported net margin is 1.94% and EBITDA is $45.473 million. The balance of quality metrics is weak: the composite grade is C with an overall score of 2, and several component signals are at the lowest end, including debt-to-equity, valuation, and asset-return measures.
Recent momentum. Earnings execution has been mixed, with beats in 5 of the last 8 quarters, including a 100.0% surprise on February 11, 2026, when EPS came in at 0 versus an estimate of negative 0.72. However, the bigger issue is corporate distress: the company disclosed that it filed a voluntary Chapter 11 petition on December 14, 2025. That restructuring event overwhelms the otherwise decent recent beat pattern and is the main reason this stock lands last despite its well-known robotics brand.
What they do. Teradyne is best known for automated test systems for semiconductors, but it also operates a dedicated Robotics segment. That segment provides collaborative robotic arms and autonomous mobile robots for manufacturing, logistics, and industrial customers, giving investors exposure to robotics through a larger, diversified automation and test platform.
Why it fits. Teradyne fits this list because it offers real commercial robotics products rather than concept-stage systems, and management has explicitly identified collaborative arms and autonomous mobile robots as part of a meaningful operating segment. It also benefits from the broader automation cycle through both robotics and semiconductor test, which can provide resilience if one end market softens.
Numbers that matter. Teradyne combines scale with strong profitability: revenue is $3.786838016 billion, EBITDA is $1.161465984 billion, gross margin is 58.7%, operating margin is 37.61%, and net margin is 22.55%. Growth is also strong, with revenue up 87.0% year over year and earnings up 314.8%, while EPS is expected to rise from $5.40 trailing to $9.5132 next year. The main trade-off is valuation, with a trailing P/E of 59.5407 and forward P/E of 51.0204, which helps explain why a high-quality business ranks only sixth in a robotics list that includes some more direct-play names.
Recent momentum. Execution has been excellent, with beats in 6 of the last 7 reported quarters. Most recently, on April 28, 2026, EPS of $2.56 topped the $2.12 estimate by 20.8%, following a 30.4% beat in February. Analyst sentiment is constructive but not euphoric, with 2 buys, 4 holds, and 1 sell contributing to a consensus rating of 4 and an average target of $369.5294.
What they do. Zebra sells automatic identification and data capture solutions across mobile computing, barcode scanning, RFID, industrial machine vision, fixed industrial scanners, real-time location systems, workflow software, and cloud-based services. Its business is less about building humanoids or delivery bots and more about supplying the digital visibility, sensing, and workflow layer that makes modern automation systems work.
Why it fits. Zebra earns a place because robotics adoption in warehouses, retail, healthcare, and logistics depends heavily on asset visibility, machine vision, RFID, and frontline workflow tools. In other words, it is an enabling-technology play on robotics and automation rather than a robot OEM, which can make it a steadier way to participate in the theme.
Numbers that matter. Zebra generates $5.583000064 billion in revenue and $1.026 billion in EBITDA, with a 48.2% gross margin, 14.98% operating margin, and 7.49% net margin. Revenue growth is 14.3% year over year and earnings growth is 3.8%, while EPS is projected at $20.6742 next year versus trailing EPS of $8.27. Valuation looks more reasonable than some higher-growth robotics names, with a trailing P/E of 29.8851 and a forward P/E of 13.9082, although the composite grade is only B because leverage metrics are weaker.
Recent momentum. Few companies on this list have matched Zebra’s consistency, with beats in 7 of the last 8 quarters. The latest report on May 12, 2026 showed EPS of $4.75 versus a $4.13 estimate, a 15.0% surprise. Analysts are broadly constructive rather than aggressive, with 2 buys and 8 holds supporting a 4.0526 consensus rating and an average target of $328.0012.

What they do. Symbotic develops automation technology for modern warehouses, focused on automating the processing of pallets, cases, and individual items. Its systems are designed to improve front-end supply-chain efficiency, making it one of the clearest public-market plays on large-scale warehouse robotics.
Why it fits. This is one of the most direct thematic fits on the list because warehouse automation is one of the fastest-commercializing parts of robotics. Symbotic’s relevance is reinforced by the theme backdrop itself: the company reported 2025 revenue of $2.247 billion and continues to scale AI-enabled warehouse robotics, showing that this is already a material operating business.
Numbers that matter. Revenue is $2.517042944 billion, and year-over-year revenue growth is a healthy 23.1%, but profitability remains thin. Gross margin is 20.4%, operating margin is 1.09%, and net margin is negative 0.29%, while EBITDA is just $22.643 million. The stock also screens as expensive on forward earnings, with a forward P/E of 149.2537, and the composite quality grade is only C- because returns and balance-sheet-related factors remain weak.
Recent momentum. Symbotic’s earnings pattern has been volatile but often impressive, with beats in 5 of the last 8 quarters. On May 12, 2026, EPS of 0.4489 beat the 0.1091 estimate by 311.5%, following a 625.5% surprise in November 2025. Analysts still lean positive, with 2 buys and 8 holds producing a 3.8421 consensus rating and an average target of $65.3988.
What they do. Serve Robotics designs, develops, and operates low-emission self-driving robots for food delivery in public and commercial spaces. Unlike companies that mainly sell hardware, Serve is building an operating platform around autonomous last-mile delivery, which makes it a more service-oriented robotics business.
Why it fits. Last-mile delivery is one of the more visible emerging robotics use cases, and Serve has tangible commercial traction. The theme backdrop notes that the company expanded its fleet to 2,000 deployed robots and raised 2026 revenue guidance after acquiring Diligent Robotics, which is exactly the kind of real-world deployment evidence investors should look for in this space.
Numbers that matter. Serve is still very early financially, with revenue of just $5.195 million and EBITDA of negative $134.783008 million. But top-line growth is extraordinary at 578.2% year over year, showing that the business is scaling from a small base. Profitability remains deeply negative, with gross margin at negative 441.1%, operating margin at negative 1,673.49%, ROE at negative 51.96%, and ROA at negative 32.81%, so this is a high-upside but high-risk robotics name rather than a proven compounder.
Recent momentum. Earnings execution has only recently started to improve. Serve beat estimates in its last two reports, including EPS of negative 0.50 versus an estimate of negative 0.5067 on May 8, 2026, but it has beaten in only 2 of the last 8 quarters overall. Analyst sentiment is unusually bullish despite the losses, with a consensus score of 5 and an average target of $18.45.

This list was built from US-listed robotics and automation-related stocks with market capitalizations above $500 million, then ranked by investment quality rather than pure thematic excitement. The ranking emphasizes our composite quality grade first, then considers profitability, revenue and earnings growth, earnings-surprise consistency, and analyst sentiment. Companies with direct robotics exposure, enabling automation technologies, or platform-level warehouse and delivery systems were all eligible. The list is refreshed monthly, which means the order can change as new earnings reports, guidance updates, and financial statements alter the balance between growth, quality, and execution.
