MobileRanger Flash3-D image showing excellent depth
data across undifferentiated surfaces on walls and floor.

MobileRanger C3-D shows excellent outline detection, and lower error rates, with far better speed than ordinary stereovision systems.

Robots typically must avoid obstacles of different heights. MobileRobots Inc offers three types of 3D avoidance sensors at 3 different prices for different applications: All of the following sensors are integrated for avoidance in all MobileRobots autonomous navigation software. Note that although some sensors have low error rates, none is perfect.

Beta Model: MobileRanger Flash3-D integrated TOF camera currently avoids positive obstacles with high reliability. While most commercial TOF cameras have been made to operate in static applications, Flash3-D has both temporal and spatio modes for compatibility with moving platforms. The 8cmDIA X 11cm long Flash3-D has a 70x52 degree FOV, with a minimum range as low as .2m and maximum range of four meters or more, with up to 15W Laser power. Range varies with programmable lighting strength; Light power out is maximum 3.5W. Operating temperature range is 0 - 40° C. Physical dimensions approx 80mm DIA X 110mm long. WIN or Linux.

MobileRanger Flash3-D can detect distances even on undifferentiated surfaces; it does not require edge detection so it works on monotone surfaces and in low-light conditions that can fool stereovision. Flash3-D data is also useful for object and gesture detection and recognition as well as obstacle avoidance. Includes lo-res BW image data in addition to range. Appropriate for commercial and research applications.

MobileRanger C3D, a stereovision-based sensor, provides affordable sensing of positive obstacles. The stereovision excels over other systems because it off-loads initial depth calculations to an FPGA,reserving the robot's native computing resources for other tasks. MobileRanger C3D operates at 30 frames per second DEPTH READINGS (not just raw data) for 752x480 images. Both sensors integrate range data with obstacle avoidance in ARIA, ARNL, MOGS and Motivity. This means that MobileRobots platforms with MobileRanger C3D or Flash3D can automatically avoid tables, shelves, limbs and other objects often missed by planar sensors. Includes lo-res BW image data in addition to range. Appropriate for research applications. More details.

MobileRobots Sonar Sensors These low-cost integrated sensors, ganged onto sensor rings on many robot platforms, provide a means for students to gain experience with avoidance sensors in the classroom. They may also be used in redundant situations in commercial systems -- for example, in concert with alarms -- however the error rate is high.
