Off-line controller design for reliable walking of ranger

Matthew Kelly, Matthew Sheen, Andy Ruina
2016 2016 IEEE International Conference on Robotics and Automation (ICRA)  
We present a method for designing a walking controller for the walking robot Cornell Ranger.  ...  We demonstrate this walking controller on the Cornell Ranger, and find that the resulting gait is comparable to that of a previous (hand-tuned) controller, with regard to energy use, speed regulation,  ...  To avoid controller tuning on mechanical hardware, we turn to off-line model-based optimization for controller design.  ...

Pranav A. Bhounsule, Jason Cortell, Andy Ruina
2012 Adaptive Mobile Robotics  
We present the design and control of an energy-efficient, knee-less, essentially planar, four-legged bipedal robot called Ranger.  ...  Key design features are: a light weight and high strength box body, low-inertia leg design for fast and efficient swing, foot actuation that combines toe-off and ground clearance, a steering mechanism  ...  The broad goal of the Ranger project 7 is to develop a reliable robot capable of walking long distances on minimal amounts of energy.  ...

2014 Proceedings of the 2014 ACM/IEEE international conference on Human-robot interaction - HRI '14  
Our findings hold implications for the design of interactive robots for children, and may also serve as an example of evaluating an early version of a prototype in a real-world setting.  ...  We present the design approach and evaluation of our prototype called "Ranger". Ranger is a robotic toy box that aims to motivate young children to tidy up their room.  ...  We also thank Maya Cakmak and the reviewers for their help in refining this article, as well as Frédéric Kaplan and Fanny Riedo for their ideas.  ...
