The Robot Stops Pretending One Gripper Is Every Tool
SwapBot turns household implements into tactile end effectors; tactile demonstrations raised contact-rich policy success by 15 to 25 percentage points over RGB alone.
Summary
SwapBot turns household implements into tactile end effectors; tactile demonstrations raised contact-rich policy success by 15 to 25 percentage points over RGB alone.
Cooking tasks demand forceful cutting, gentle brushing and precise placement, often with tools that a universal gripper handles awkwardly. SwapBot uses a fixed robot-side coupling and low-cost adapters that turn common household tools, including articulated tools, into interchangeable end effectors. Each adapter includes compact tactile sensors and can be swapped autonomously. User studies reported lower teleoperation time and workload, and demonstrations trained policies for tasks including cutting and cooking tofu, stirring salad and flipping meat. In ablations, tactile-augmented demonstrations improved success by 15 to 25 percentage points over RGB-only policies. The results cover the tested tools, adapters and tasks rather than general household autonomy.
