Weevils Drones designs and manufactures indigenous tactical UAV, ISR, fixed-wing, VTOL, and counter-UAS systems at IIT Kharagpur STEP.
Comms-relay and ISR airframes flown in the high passes, next to the formations that depend on the link holding.
Mission-ready UAV systems engineered for persistent surveillance, mapping, inspection and data-driven operations across commercial and strategic environments.
Long-endurance aerial platforms for real-time intelligence, reconnaissance, perimeter monitoring and situational awareness.
High-precision UAV workflows for DGPS/RTK mapping, terrain modelling, asset surveys and geospatial data acquisition.
Aerial inspection solutions for utilities, infrastructure, industrial assets and difficult-to-access environments.
Mission-specific payload integration, autonomous systems and platform engineering tailored to operational requirements.
Compact VTOL platform combining vertical launch and recovery with efficient fixed-wing cruise. Apollo carries up to 1 kg, reaches 35–40 km without payload, and integrates a 3-axis stabilized visible/thermal camera with live video and intelligent target tracking.
Gandiva is a counter-drone system in two parts: a detection layer that uses multi-sensor fusion to spot and track a hostile UAV, and an interceptor layer that deploys drones to bring it down — the whole engagement run from a single Ground Control Unit. Each interceptor is a carbon-fibre 450-class quadcopter, stabilised by an ArduPilot autopilot and fitted with a kinetic tip. It dashes at 90–126 km/h, and 2–10+ can fly together for a layered, sensor-cued intercept.
Swarm is a coordinated team of drones: one 'master' leading any number of others, all built on the 5-inch Zeus quadcopter. They fly as a single formation, covering more ground than a lone UAV while the mission carries on even if a drone drops out. If the master is lost or neutralised, another drone automatically takes over the lead and the rest fall in behind it — so there's no single point of failure. The swarm's intelligence runs onboard each aircraft, coordinating the formation over a long-range radio link, with every drone on a proven ArduPilot autopilot for stable, GPS-guided flight. Automatic return-to-launch and auto-land failsafes bring the drones home safely, and the whole swarm is flown and monitored from a single ground station for tactical, surveillance and autonomy research.
10-inch FPV quadcopter with fibre-optic tether for electronic-warfare-resistant command and video. Four range configurations (2 / 5 / 10 / 20 km), 90–100 km/h cruise, analog or digital HD video options. The GCU converts digital signals to optical for jam-proof terminal control.
Two-stroke fuel-engine target drone on a balsa-and-plywood airframe, configurable with OS 0.46 / 0.56 or DA / DLE 35 engines. Built for air-defence unit training and gunnery practice. Simulates hostile-aircraft flight characteristics and radar signatures more safely and economically than manned targets.
A low-cost fixed-wing built from balsa and plywood and flown line-of-sight through FPV goggles. Battery-electric, shipped as an ARF kit, roughly 3 kg all-up with a 1 kg payload bay and 10–15 minutes on a charge out to 5–6 km. No autopilot suite: manual stabilisation and a clean video feed to the pilot. The wooden airframe keeps unit cost low enough to fly it as an entry-level trainer or treat it as expendable on short-range tactical tasks.
Lightweight mid-range fixed-wing UAV for tactical reconnaissance and survey missions. Composite or laser-cut balsa airframe, battery-electric propulsion, ArduPilot autopilot with Auto / Loiter / Stabilize / RTL flight modes. RF-primary comms with optional GPS telemetry.
Production-tuned variant of the Icarus composite VTOL, sharing its CF/FG airframe and ArduPilot autopilot. Configurable electric or IC-engine propulsion, ARF kit assembly. 50–60 min endurance, 60–80 km operational range on a single charge, GPS-primary comms with RF backup.
Composite VTOL platform for long-range ISR, mapping, and surveillance missions. Built on a carbon-fibre / fibreglass airframe with ArduPilot-based autopilot and configurable electric or IC-engine propulsion. Shipped as an ARF kit; GPS comms with RF fallback.
Hybrid carbon-fibre and fibreglass FPV platform that bridges high-speed racing and stabilised camera drones. The rigid CF core keeps manoeuvres precise while impact-resistant fibreglass arms and reinforced motor mounts absorb the hard landings of the training phase. An ArduPilot flight controller gives new pilots a safety net: auto-level Stabilize, GPS Loiter, and one-switch Return-to-Launch with signal-loss and low-battery failsafe. Live telemetry (voltage, GPS, altitude, speed) streams straight into the pilot's goggles.
Awarded at East Tech X, India's Defence Technology Symposium in Sikkim. The recognition followed the year's fielded work on tactical and ISR platforms.
CEO Ashis Saha met Mr. Sanjay Seth, Minister of State for Defence, at a dinner on 19 September. The conversation covered the company's roadmap and where indigenous UAV makers fit into India's defence priorities.
Three days exhibiting at East Tech 2025 in Ranchi alongside the wider defence-tech industry. The company received a Certificate of Appreciation for its contribution.
The drone manufacturing facility at IIT Kharagpur opened under the STEP (Startup Ecosystem Promotion) program. The workshop now anchors the company's R&D and production for indigenous UAV platforms.
