FAQs: Custom Tracks for Robotics Applications

Custom track components are engineered for enabling tracked mobility for robots which must operate over rough, stair, and difficult surfaces. These include drive sprockets which transmit motor torque to track belts, track links which provide flexible yet durable track surface, idler wheels which preserve track tension, guide wheels which prevent track derailment, tensioner assemblies which adapt track tension to terrain, support rollers which distribute track load, and custom track pads for specific surfaces like concrete, gravel, mud, and stairs.

Lightweight construction is crucial for reducing overall vehicle mass, payload capacity, battery life, and overall cost, which is important for robots weighing up to 100 kg. Aluminum is easily machinable to provide over 100 various geometries for complex sprocket designs. Steel 4140 and 8620 are preferred for providing high strength, toughness and impact resistance for heavy duty tracked vehicles which support payloads over 500 kg. Tool steel provides maximum wear resistance for sprocket teeth and guide surfaces. Lastly, stainless steel provides corrosion resistance for marine and wet environment applications, while still possessing decent strength.

Complex sprocket geometries along with precise tooth profiles are crafted using multi-axis CNC milling. CNC turning generates spindle-turned cylindrical components such as idler wheels, support rollers, and shafts with specified diameters. Gear hobbing and wire EDM are used to cut sprocket teeth along specified pitches and profiles to ensure disengagement is smooth. Carburizing followed by quenching to create a surface hardness greater than 58 HRC and additional wear resistant is a track component's heat treatment. Post heat treatment surface grinding is done to restore the surface to specified dimensions and counter excessive heat treatment distortion. Coordinate drilling for creation of mounting holes and lubrication passages is used machining method.

For sprocket engagement, we achieve tooth pitch accuracy of ±0.005 inches, bore dimensions of ±0.002 inches for fitting a bearing, tooth profile precision of ±0.003 inches for power transmission, concentricity of 0.005 inches, and balance to within ±0.010 inches. Overall dimensions and surface hardness uniformity of 2 HRC ensure consistent wear across the teeth.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.

Yes, all components incorporate comprehensive documentation maintained within a quality management system certified to ISO 9001 standard which includes certifying material traceability for elements within the components, certifying the heat treatment of components, measuring and certifying the dimensional compliance of elements within components in alignment with specified designs, certifying hardness of elements within the components in critical wear surfaces, and certifying components in tracked robots for reliable rugged terrain navigation across hundreds of operating hours, and certifying the coated elements for mobility which must sustain and bear payloads ranging from 10 to 1000 kilograms.

We provide comprehensive finishing solutions tailored to aerospace requirements:
Anodizing (Type II and Type III)
Passivation for corrosion resistance
Precision polishing for aerodynamic surfaces
Custom protective coatings and thermal barriers

10–15 business days is the lead time for standard sprockets and idler wheels; this includes the time for machining and heat treatment. For full custom track systems, it integrates features and takes about 4–6 weeks. For rapid tracked vehicle testing and terrain validation, prototype sets of components can be done within 7–10 days

Of course. For inspection robots, we design lightweight track systems that minimize ground pressure for use on delicate terrain. Other designs include aggressive sprocket profiles for maximum traction on loose terrains like sand and gravel, stair-climbing track geometries with optimized pitch and pad designs, and amphibious track components made of corrosion-resistant materials for operation in water. We also build high-speed track systems for patrol robots that reach speeds of more than 5 meters per second, and custom track pads with application-specific tread patterns for use on concrete, asphalt, or off-road conditions.

Having accurate sprocket teeth pitches to within ±0.005 inches allows for guaranteed positive engagement of track links, and no slippage that results in losing control and traction. Smooth power transmission is achieved as a result of precise tooth profile construction and reduces noise, vibration, and wear. Proper sprocket construction and treatment results in surface hardness of over 58 HRC and sprocket life of over 500 hours of operation. Controlled bore dimensions result in bearing fit that prevents wobble and misalignment. Optimal geometry for strategic weight reduction offers maximum payload capacity. Construction with quality materials yields the required impact resistance for negotiating obstacles. Mechanical life is prolonged with balanced components that reduce vibration and sensor accuracy is improved. Durable construction allows for reliable operation over different terrains characterized by slopes, stairs, debris, and rugged surfaces.
