When to pick which
Choose the Tunabot Flex for specialized aquatic applications such as environmental monitoring in sensitive marine ecosystems or covert defense surveillance. Its ultra-lightweight 0.19 kg frame and bio-inspired propulsion allow it to reach speeds of 1.173 m/s, mimicking natural tuna movement for low-impact observation. Research institutions studying fish locomotion or agencies requiring long-duration underwater scouting up to 6.25 hours should prioritize this platform. The Tunabot’s agility and small form factor make it ideal for navigating tight underwater structures where traditional, bulky ROVs or stationary industrial equipment like the KUKA KR QUANTEC cannot operate.
Select the KUKA KR QUANTEC for high-volume industrial manufacturing, specifically in automotive welding or heavy-duty palletizing. With a massive 300 kg payload capacity and a 3100 mm reach, this 6-axis arm is designed for large-scale factory automation that requires precision and strength. Unlike the research-oriented Tunabot, the QUANTEC integrates directly into professional workflows via KRL and KUKA.SystemSoftware. It is the necessary choice for Tier 1 suppliers needing to manipulate heavy structural components or manage high-speed assembly lines where physical reach and mechanical power are the primary operational constraints.
