Root is an important plant organ for nutrient and water uptake from the surrounding medium such as soil. Due to its special growing environment and structural complexity, it is more difficult to quantify plant root than its shoot. Observation and measurement of plant root in situ have been the technical bottleneck to understand root systems. Available(More)
This paper presents the Axel robotic rover which has been designed to provide robust and flexible access to extreme extra-planetary terrains. Axel is a lightweight 2-wheeled vehicle that can access steep slopes and negotiate relatively large obstacles due to its actively managed tether and novel wheel design. This paper reviews the Axel system and focuses(More)
Root is an important organ for Plant to uptake nutrient and water from the surrounding soil. And the capability of plant to obtain nutrient and water is closely relevant to its root distribution and architecture under ground. Quantitative measurement and analysis of plant root architecture parameters are very important for understanding and study growth of(More)
Root is an important organ for plant to uptake nutrient and water from the surrounding soil. And the capability of plant to obtain nutrient and water is closely relevant to its root distribution and architecture under ground. Soil is the source of water and nutrients for plant; however, it also obstructs the observation and measurement of the root system. A(More)
