Company profile

researched Sep 2026

Tennibot is a sports robotics company headquartered in Auburn, Alabama that designs and manufactures AI-powered training equipment for racquet sports. Its product line consists of two families: the Partner, an autonomous ball machine, and the Rover, an autonomous ball collector that gathers balls from the court while play continues. The Partner V2 flagship drives itself around the court to feed balls from varying positions, carries a 140-ball hopper, and is priced at $2,275; the Partner Lite is a lighter 25 lb stationary model priced at $1,525 and sold in tennis/padel and dedicated pickleball configurations. The Rover, priced at $2,275, pairs with both Partner models and operates on hard, clay, grass and artificial turf surfaces. A Partner plus Rover bundle is listed at $3,995.

All machines run the same AI drill system, spin and placement control, and companion app, with iOS and Android control plus Apple Watch support. The Partner uses cameras, sensors and computer vision to read court lines, the net and player position, calibrating itself and navigating around obstacles such as net posts and benches. Stated specifications include 4K cameras with 3D ball tracking, roughly 4–5 hours of battery life, and, for the V2 redesign, 13.6% lower weight, 14.4% smaller size, 37% more vertical range and upgraded braking motors for transitions between shot types. Machines are usable indoors and outdoors and are not recommended in heavy rain.

The company positions its equipment for individual players, coaches, clubs, schools, academies and training facilities across tennis, pickleball and padel, with commercial pricing available for facilities.

Founding story

Tennibot originated when co-founder Haitham Eletrabi, practicing with a ball machine, concluded he spent more time collecting balls than hitting them. He was introduced to Lincoln Wang, a recent master's graduate and tennis enthusiast, through an Auburn business professor, and the two developed the product alongside playing doubles. The company describes the product as moving from a dorm-room prototype through years of designing, prototyping, testing and refining.

Business model

Direct-to-consumer hardware sales through tennibot.com, with machines built to order in Auburn, Alabama and shipped by the company. Purchases include a 60-day return window, a 3-year limited warranty, free US shipping and returns, and monthly financing at checkout; international shipping is offered with rates varying by country. The app, AI drills and over-the-air updates are included with the machine, with no subscription.

One-time hardware purchases: Partner Lite at $1,525, Partner V2 at $2,275, Rover at $2,275, and a Partner plus Rover bundle at $3,995, with optional monthly financing. Special pricing is offered for commercial use by clubs and facilities. No recurring software fees.

Traction

The Partner V2 product page shows a 4.8 rating based on 312 reviews. The company states its machines are used by coaches and clubs worldwide and that it serves tennis, pickleball and padel players internationally. Earlier coverage cited a successful crowdfunding campaign, pre-orders on the website and demand that prompted production and staffing increases; build-to-order machines ship roughly 6 to 7 weeks after order.

Latest developments

The Partner Lite, a 25 lb stationary AI ball machine from $1,525, is marketed as new, alongside a redesigned Partner V2 that is lighter and smaller with greater vertical range, upgraded braking motors and Apple Watch control. Tennibot was named to the Robot Report RBR50 list in 2025.

▸Full profile — market position, technology, go-to-market, geography, history, risks & controversies

Market position

Positions itself as the only autonomous ball collector on the market and as the only AI ball machine company manufacturing in the United States. Recognition includes MUSE Design Awards gold, TechCrunch Disrupt innovation winner, CES Innovation Awards honoree, European Product Design Award, SoGal Ventures, Silicon Valley Robotics finalist, TBD Tennis Innovation Week innovation award, Alabama Launchpad and Tennis Industry Association awards, and inclusion in the Robot Report RBR50 for 2025. Media coverage has included Time Magazine, Forbes, BBC, Yahoo, Huffington Post, LA Times, Tennis Channel and TechCrunch.

Emphasizes autonomy and realism: a ball machine that drives around the court and repositions as a rally develops, paired with an autonomous collector so practice is not interrupted by ball pickup. Other stated differentiators include AI-generated custom drills rather than fixed patterns, 4K camera 3D tracking, low weight (25 lb Partner Lite), operation on all court surfaces, US hand-assembly with bench and on-court testing of every unit, a 3-year warranty and a 60-day risk-free trial.

Technology

Computer vision and autonomous navigation: 4K cameras with 3D ball tracking, sensors that detect court lines, the net, player position and obstacles, and self-calibration before drives into feeding positions. AI generates custom drills, automatically configuring shot placement, pace, spin and sequences. Control is via iOS/Android apps and Apple Watch, with over-the-air feature updates. The Partner V2 adds braking motors for smoother transitions between shot types and increased vertical range. The company states it holds over 17 patents and trademarks covering its ball machine and ball collector technology.

Go-to-market

Direct online sales supplemented by demo bookings, uncut product demonstration videos, player and coach testimonials, and customer-service-driven word of mouth. Leadership has described hand-delivering early units, collecting direct feedback from early adopters, deliberately limiting early production batches, and providing loaner units when problems arise, targeting a premium, socially networked recreational tennis audience.

Individual players from beginner to touring professional, plus coaches, tennis clubs, schools, academies and training facilities in tennis, pickleball and padel.

Geography

Headquartered and manufacturing in Auburn, Alabama, United States, with free US shipping and returns and international shipping to many countries.

History

The about page states Tennibot was founded in 2016 in Auburn, Alabama by Haitham Eletrabi and Lincoln Wang; other coverage also gives a 2016 founding date. The company emerged from Auburn University and the university's New Venture Accelerator and Tiger Cage competition, and has been housed in the City of Auburn's incubator system at the Auburn Center for Developing Industries, where it leased office and manufacturing space before outgrowing the facility ahead of a move to a newer city incubator in Auburn Industrial Park. It participated in the Techstars Sports Accelerator in 2020 and is a Techstars alumnus. Initial ball-collector units shipped around the onset of Covid-19, which disrupted supply chains; the company produced small batches of five to ten systems while incorporating early-adopter feedback. It later introduced the Partner V2 ball machine and, more recently, the Partner Lite.

Risks & controversies

Supply chain disruption during the Covid-19 period affected the company as it began shipping initial units, and management has described a cautious venture capital environment. Products are premium-priced and built to order with a 6–7 week lead time, and are not recommended for use in heavy rain or standing water.
