An unmanned, autonomous, battery powered and rechargeable vehicle having multiple sensors for collecting, analyzing, storing and transmitting data related to environmental and plant growth data in greenhouse environment. The mobile vehicle navigates between plant rows tracking a designated and repeatable path several times daily, collecting data from the plant root ball up to and including the plant canopy, without touching, sampling, or impacting plant growth. A telescoping arm ensures the sensor platform height is optimized relative to the plant canopy height.
