Stretch is a mobile manipulator for professional research; the current Stretch 4 has a telescoping arm and an omnidirectional base. A research institution can assess the platform for a defined manipulation task in a prepared indoor space. Specify the object, base starting point and intended gripper position. The development team should record the software version and installed tool so experiments can be reproduced. Arm position belongs in any comparison of payload and reach. Also plan who operates the platform and which measurements are retained. For project planning, a demonstration with the team’s own objects gives a more concrete basis than a general presentation without recorded task conditions and a repeatable setup.
