UV-C disinfection robots and medicine dispensers, built in Hyderabad.

Our UVRova robots have disinfected hospital ICUs, operating theatres and wards since 2020. We design every machine, wire it and assemble it in our own workshop, and we are now building robots that hand out medicine and tend shrimp ponds.

UVRova ST running in an operating theatre in Hyderabad. The blue glow is visible light from the lamps; the 254 nm UV-C itself cannot be seen.

Disinfection

UVRova

Chemical fumigation shuts a room for hours. UVRova adds a UV-C step after cleaning instead: staff wheel the robot in, leave, and press start. The 254 nm light breaks the DNA and RNA of bacteria and viruses on the surfaces it reaches, and leaves no residue, so the room is ready a few minutes after the lamps go off.

ST, the room robot

A column of high-output UV-C tubes on a wheeled base, lighting the room in every direction. Plug it in, press the button and walk out. Sensors watch for people and switch the lamps off within a second if anyone comes in.

Height: 170 cm
Footprint: 45 × 45 cm
Weight: 50 kg
Lamps: 254 nm UV-C tubes
Power: 220 V mains
Run time: Button: 5 min short press, 10 min long press. Phone app: 5, 15 or 25 min
Safety: Presence sensing, lamps off in under 1 s

BR, the bed robot

Made for ICU beds between patients. A short press keeps it in one place beside the bed. A long press sends it on a loop around the bed so the light reaches both sides of the mattress and the rails.

Height: 150 cm
Footprint: 50 × 65 cm
Weight: 40 kg
Stay in place: About 7 min, for tight spaces
Around the bed: About 5 min, when there is room to move
Power: Mains

Genie, the compact unit

A cordless cabinet for clinics, offices and small rooms. Press the green button and walk away: the lamp column rises 50 cm out of the cabinet in about ten seconds and folds back when the cycle ends.

Height: 70 cm closed
Footprint: 30 × 30 cm
Covers: About 100 sq ft
Cycle: About 3 min
Power: Battery
Lamps: Ozone-free 254 nm, with presence sensing

Where they went

In July 2020 a UVRova BR was donated for the COVID-19 ICU at Gandhi Hospital, Telangana's main COVID-19 hospital, and handed over to the state's IT and Industries Minister, K. T. Rama Rao. Star, Virinchi and Medicare hospitals in Hyderabad used the robots too, along with dental clinics and commercial kitchens. In all, UVRova sales came to about ₹2 crore during the pandemic.

Test reports and certificates

Revin Labs, Hyderabad, report RLPL/016/AMV/R/20/002 (PDF). About a 4-log reduction for the bacterial strains tested, on agar plates exposed to a UVRova ST for 10 minutes at 3 m.
Revin Labs, Hyderabad, report RLPLTRM2000409, 20 March 2020 (PDF). No detectable growth for the ten organisms tested on 20 exposed culture plates.
EuropeCert certificate of compliance No. 0220 (PDF). ST and BR assessed against the EU Low Voltage (2014/35/EU) and EMC (2014/30/EU) directives. Issued 25 March 2020, valid to 24 March 2021.

Each result applies to the organisms, plates and exposure set out in that report. Dose falls with distance and shadowed surfaces get less, so results in a room depend on where the robot stands. UVRova is used only in empty rooms; UV-C harms skin and eyes.

Why it matters: out of every 100 patients in acute-care hospitals, 7 in high-income countries and 15 in low- and middle-income countries pick up at least one infection during their stay (WHO, 2022).

Disinfection, next

AERO Design

UVRova made to drive itself down an aircraft aisle.

A T-shaped boom of UV-C lamps spans the seat blocks on both sides, so the light reaches seat tops and sides, armrests, overhead bins and the passenger service panels above the seats. One person starts it with a single button, and infrared sensors keep it in the aisle as it works the cabin row by row.

Model: UVAR-01
Target speed: One row every 10 s
Footprint: 35 × 50 cm
Height: 180 cm
Power: 220 V AC, 10 A

Medication

Medicine on time, at home

For long-term illnesses, patients in developed countries take only about half of their medicine as prescribed, and fewer do elsewhere (WHO). AutoPill gives the right tablets at the right time and records that they were taken. AutoStore applies the same idea to a pharmacy's stock.

AutoPill Working prototype

A home pill dispenser that holds a month of medicine and reports every dose.

The doctor's or carer's schedule is set on Central Control, a cloud server.
At dose time, the cabinet sounds a buzzer.
The patient presses the button and a cup with that dose comes out.
A built-in SIM reports the dose to Central Control, which can also hold a dose back or move it.

Capacity: 15 blister packs of 28, 420 tablets
Doses: Up to 15 different tablets or capsules a day, each at its own time
Refill: Lift the top flap and slide in a blister
Size: 350 × 250 × 300 mm, 12 kg
Body: Aluminium, stainless steel and ABS

AutoStore Design

A robotic cabinet that stores blister packs by brand and pushes the right one into a tray when it is ordered.

Each pod is a cabinet of side drawers. Staff log new stock and its drawer from a phone app, and orders, stock levels and brands are run from one control centre on a phone or PC. One control system runs up to ten pods.

Brands: About 500 per pod
Stock: About 5,000 blister packs
Speed: About 5 packs a minute
Size: 1.75 m high, 1.25 m long, 0.8 m deep, about 85 kg

On the drawing board

AutoPose

A floating robot designed to monitor shrimp pond water, aerate it when dissolved oxygen drops and dispense feed from an onboard hopper. Farmers would see readings and steer the robot from a phone.

Load carrier for army logistics

A semi-autonomous, all-terrain vehicle that follows a squad and carries 500 kg of its kit: rucksacks, water, food, ammunition, radios and battery chargers, or a stretcher when needed. Soldiers reach the objective fresh instead of worn out from the march. The idea follows the US Army's Small Multipurpose Equipment Transport programme.

Robotic chef kiosk

A fast food kiosk where robotic arms cook behind a shatter-proof window. Customers order and pay on a touch screen and collect from a delivery slot. A trained model watches each step and corrects the arms, cameras let a central office check the food, and a person stands by behind the kiosk.
