FlySpark TK990 Stair-Climbing Heavy-Duty Tracked UGV Robot Chassis | 80kg Payload, 4h Endurance, 35° Climb, 180mm Obstacles, 200mm Fording & Serial/CAN

FlySpark TK990 is a heavy-duty stair climbing tracked robot chassis: a compact, all-terrain UGV (unmanned ground vehicle) base for robots that need to work both inside buildings and outdoors. At approximately 990 × 620 × 335mm it fits through doors and corridors, yet it carries an 80kg rated payload, runs about 4 hours on its 48V 60Ah lithium battery, climbs 35° slopes and stairs, and rides on 12 sets of independent suspension shock absorbers for smooth, stable traction on uneven ground.

Two 48V 750W brushless DC motors drive 87mm-wide reinforced rubber tracks with an embedded Kevlar fibre tensile layer, and an industrial-grade 1000-line incremental photoelectric encoder on each side gives precise speed feedback for closed-loop control. Speed is adjustable from 0 to 9km/h, a motor brake holds the chassis on slopes, and track-differential steering lets it spin in place in tight spaces. It surmounts 180mm obstacles and fords 200mm of water. The carbon-steel hull is finished with baked electrostatic paint, sealed to IP54 as standard with an IP66 build available, and operates from -20°C to 60°C. The TK990 is part of the FlySpark Unmanned Ground & Surface Vehicles (UGV / USV) range, supplied and integrated in India for defence, security, industrial and research users, with export support on request.

WHY CHOOSE THE TK990 HEAVY-DUTY TRACKED UGV CHASSIS

The TK990 is designed as an open all-terrain robot platform rather than a closed vehicle. The main controller runs open-loop and PID closed-loop control and accepts commands from a host computer over Serial or standard CAN with a published communication protocol, while reporting linear and angular velocity back. That makes it straightforward to add your own autonomy computer, ROS navigation stack, lidar, depth cameras, GNSS, manipulators or mission payloads without reverse-engineering the drive system.

Payload power comes straight from the main pack through reserved 48V 10A, 24V 5A and 12V 5A outputs, so cameras, radios, computers and actuators can run without extra batteries. The standard 2.4GHz remote control gives forward, reverse, left, right and spin-in-place control with about 200m line-of-sight range, and replaceable long-range remote controllers, real-time HD 1080P video transmission, mesh self-organizing network control and 4G/5G remote control are available as upgrades.

IMPORTANT USE NOTE: The TK990 is a mobile robot chassis for lawful industrial, security, research, rescue, education and logistics applications. Operate it only on sites where you have permission, keep people clear of the tracks during operation, respect the 80kg rated load and 200mm fording limit, test stair climbing with your actual payload before deployment, and follow local safety, RF and site regulations. Optional radio links must be used only on legally permitted frequencies and power levels.

FREQUENTLY ASKED QUESTIONS:

Q: What is a tracked UGV? A: A tracked UGV (unmanned ground vehicle) is a remotely operated or autonomous robot vehicle that runs on continuous tracks instead of wheels. Tracks spread the load and grip loose or uneven ground, which lets a tracked robot climb stairs, cross obstacles and work off-road where wheeled robots struggle.

Q: What is the FlySpark TK990? A: The FlySpark TK990 is a compact, heavy-duty stair climbing tracked robot chassis with an 80kg rated payload, 4 hours endurance, 35° climbing and 12 sets of independent suspension. It is an open all-terrain robot platform for patrol, inspection, stair-climbing, transport and research robots.

• Q: What is the payload capacity of the TK990?
• A: The rated load capacity is 80kg on the flat top deck, which is roughly equal to the chassis’ own 80kg curb weight.

Q: How long does the TK990 run on one charge, and how is it charged? A: Endurance is about 4 hours from the standard 48V 60Ah lithium battery, depending on payload, terrain, speed and temperature. The pack has overcharge and over-discharge protection and charges from the included AC 220V charger through an independent aviation plug.

Q: What is the top speed, and what motors drive the TK990? A: Speed is adjustable from 0 to 9km/h. Drive comes from two 48V 750W brushless DC motors, each with an industrial-grade 1000-line incremental photoelectric encoder for accurate speed feedback and smooth closed-loop control.

Q: Can the TK990 climb stairs? A: Yes. The chassis is rated for a 35° maximum climbing angle and is designed to climb stairs and surmount obstacles up to 180mm high. Stair geometry, surface grip and payload centre of gravity should be checked for each site before deployment.

Q: What terrain can the TK990 handle? A: It works indoors and outdoors on concrete, tiles, gravel, grass, sand, mud and broken ground. It clears 180mm obstacles, fords water up to 200mm deep and its 12 independent suspension units keep the tracks in contact with uneven surfaces.

• Q: What are the dimensions and weight?
• A: Overall dimensions are approximately 990 × 620 × 335mm (L × W × H) and curb weight is approximately 80kg.

• Q: What tracks does the TK990 use?
• A: 87mm-wide reinforced rubber tracks with an embedded Kevlar fibre tensile layer for strength and stretch resistance.

Q: Is the TK990 waterproof, and what temperatures can it handle? A: The standard protection rating is IP54 (protected against dust and splashing water), and an IP66 sealed build can be configured on request for heavy rain, wash-down and dusty outdoor sites. The chassis operates from -20°C to 60°C.

Q: How is the TK990 controlled? A: It ships with a 2.4GHz remote control for forward, reverse, left, right and in-place spin turning, with about 200m line-of-sight range in open areas. Replaceable long-range remote controllers are available as an upgrade.

Q: Does the TK990 support ROS and custom autonomy software? A: Yes. The main controller supports open-loop and PID closed-loop control and accepts host-computer velocity commands over Serial or standard CAN with an open communication protocol. It reports linear and angular velocity back to the host, so a ROS navigation stack or your own autonomy software can drive it through a simple interface node.

Q: How do I integrate payloads on the TK990? A: Sensors, masts, manipulators and equipment cases mount on the flat steel top deck within the 80kg rated load, and draw power from the reserved 48V 10A, 24V 5A and 12V 5A outputs. FlySpark can prepare a mounting and wiring plan as part of the autonomy integration package.

• Q: Does the TK990 support video transmission and 4G/5G control?
• A: Yes, as options. The chassis can be configured with real-time HD 1080P video transmission, mesh self-organizing network control and 4G/5G remote control.

• Q: What power outputs are available for payloads?
• A: The power distribution system has reserved 48V 10A, 24V 5A and 12V 5A outputs for cameras, sensors, computers, manipulators and other mission equipment.

Q: What is the TK990 used for? A: Stair-climbing robots, indoor and outdoor autonomous patrol robots, off-road robots, security and explosive ordnance disposal (EOD) robot platforms, firefighting robots, cleaning, agricultural spraying, disinfection, target-carrier training platforms, scientific research and education.
