Humanoids Master Fitted Sheets: Dual Arm Tactile Benchmark Solves Bed Making

Managing large, unstructured soft fabrics like bed sheets has long stumped roboticists due to the unpredictable physics of folding cloth. The Toyota Research Institute (TRI) and Fourier Intelligence have achieved a significant breakthrough with dual-arm tactile tension control. Field tests using the Fourier GR-2 and TRI Punyo architectures reveal these units can autonomously stretch fitted sheets over heavy mattress corners without tearing the material or missing the anchor points. This marks a turning point for domestic automation, as making a bed requires simultaneous coordination of visual tracking and delicate physical pulling.

By monitoring tactile feedback directly at the fingertips, the robots keep tension strictly below a 15-newton threshold. This sub-15N limit ensures even delicate linen and cotton fabrics are handled with human-like care. The GR-2 analyses the drape of the fabric in real time through advanced vision sensors, constantly adjusting its grip to pull the elastic securely under the mattress base. Once the corners are anchored, the robot smoothly transitions into an ironing motion, sweeping its hands across the mattress to flatten wrinkles and create a perfectly tight surface suitable for a luxury hotel.

Duvet insertion has also been successfully validated using this new soft manipulation framework. The robotic system accurately identifies the hidden inside corners of the cover and matches them with the heavy inner quilt, sliding them together in a synchronised dual-arm motion. For busy households wanting to completely eliminate the tedious morning chore of making the bed, this integration of TRI software and Fourier GR-2 hardware provides a highly practical solution. Families can expect beautifully made beds every single day without lifting a finger.
