RI Seminar: Charlie Kemp : Human-scale mobile manipulators happily used in homes?

   What home robots must earn

   Kemp says a home robot must provide enough value for someone to buy it and live with its cost in space, time, and attention. He frames adoption around usefulness, ease of use, price, and safety, using the Roomba’s clear cleaning task, small size, and $200 launch price as a comparison. Personal spaces also contain people, pets, and sentimental objects, so even familiar tasks such as washing dishes can carry risks and emotional costs.

   Stretch’s minimalist design

   Kemp describes Stretch as a design from his Georgia Tech lab, later commercialized by Hello Robot. Its mobile base, lifting column, and telescoping arm use movement of the base to reduce the number of actuators while reaching floors, countertops, and wheelchair users. He argues that human-compatible dimensions do not require a humanoid form, and that lower mass and a stable base can make a robot easier to move and less hazardous.

   Building capability through a community

   Kemp shows teleoperated home demonstrations, including retrieving laundry, interacting with children, and two Stretch robots working together. He distinguishes teleoperation from autonomy and says the demonstrations show feasibility rather than completed autonomous capability. He also credits open-source software and researchers who developed an accessible web interface, navigation, and pre-grasping features.

   Mobility assistance as an early use

   Kemp sees people with mobility impairments as promising early adopters because tasks such as retrieving objects, feeding, and scratching an itch can offer meaningful independence. Henry Evans used Stretch through a web interface to perform tasks at home and connect with his granddaughter and friends; another user, Bob, used a system to bring himself a shake. Kemp says these examples also changed his view of robots’ potential to support social connection.

   Reliability, iteration, and human needs

   Kemp says home use depends on safety, daily value, and systems that people can use reliably, including their interfaces, hardware, communication, and documentation. He describes Hello Robot’s iterative approach, guided by feedback from people with mobility impairments, and says people should be involved when deciding whether a robot should fit existing habits or ask users to change them. He sees human supervision as useful in the near term and emphasizes that robots can complement people through tasks they can perform steadily.
