Hello Robot’s Stretch 4 is a new wheeled robot designed to assist in homes, potentially reaching households before humanoid robots become widely available. Unlike humanoid robots that walk and balance, Stretch 4 rolls, making it more suited to navigate the typical obstacles found in homes, such as rugs, cords, and furniture.
Practical Design for Real Homes
Stretch 4 focuses on safe movement and practical assistance, offering a wheeled base, a lifting column, and an arm for reaching objects. It’s equipped with tools for mapping, navigation, and self-charging, making it a realistic option for assisting people where they live.
Currently, Stretch 4 is intended for research and development use, with home pilot deployments planned. This approach allows for real-world testing in environments that include pets, narrow hallways, and other common household challenges.
Addressing Mobility Challenges
For homes already adapted for mobility aids like wheelchairs, a wheeled robot may integrate more seamlessly than a bipedal one. Stretch 4’s omnidirectional base, inspired by powered wheelchairs, allows it to move in any direction without turning, offering better maneuverability in tight spaces.
The robot’s advanced sensor setup, including lidar and cameras, helps it navigate and interact with its environment safely. These features are crucial for avoiding obstacles and handling objects with care, making Stretch 4 a potential asset for individuals with severe mobility impairments.
Safety and Human Involvement
Safety is a key consideration for home robots. Stretch 4 includes features like force limiting and collision avoidance, ensuring it operates safely around people and pets. While it has autonomous capabilities, human supervision remains part of its operation, providing a balance between automation and safety.
As Hello Robot continues to refine Stretch 4, its focus remains on creating a robot that assists with daily tasks, supporting independence for those with mobility challenges. While it may not have the humanoid appeal, its practical design could make a meaningful difference in the lives of many.
