Ceva, Inc. has unveiled the Hillcrest Labs MotionEngine Scout, a highly accurate dead reckoning software solution for intelligent navigation systems. Designed as a lower cost solution to camera or LiDAR-based systems for indoor robot navigation, such as robot cleaners and autonomous mobile robots (AMR) in industrial or commercial environments, the MotionEngine Scout delivers precise dead reckoning by fusing sensor data from optical sensors, inertial measurement unit (IMU) sensors, and wheel encoders.
“The sensor and processor agnostic embedded software solution fuses measurements taken from the robot’s optical flow sensor, wheel encoders, and IMU and uses this data to deliver better dead reckoning accuracy and robustness against individual sensor errors,” said CEVA. “MotionEngine Scout reduces the trajectory error by a factor of 5× in challenging scenarios, including surface flooring such as vinyl, tile, and various styles of carpet.”
The software’s algorithms are always monitoring changes in sensor performance and temperature during operation to enable the best performance. It also features intelligent power management to save power without impacting the quality of motion data.
The software solution supports a broad range of commercial IMU sensors from the leading suppliers including STMicroelectronics, Bosch-Sensortec, and TDK InvenSense, giving more supply chain options to OEMs for product selection and to reduce supply shortage risks.
For the optical flow sensor, Ceva has partnered with PixArt to incorporate its PAA5101 dual-light optical tracking sensor into the solution, to reduce development complexity and time-to-market.
The software solution expands Ceva’s sensor product line for autonomous indoor robots which includes the following IMU-based solutions: MotionEngine Robotics software, FSP200 sensor hub, BNO086 system-in-package (co-developed with Bosch), and FSM300 module. The company also offers complementary IP products required for autonomous robots, including its RivieraWaves Bluetooth and Wi-Fi platforms for connectivity and its SensPro2 sensor hub DSP which is capable of handling multiple sensor processing workloads from sensors such as cameras, LiDAR, and IMUs.
For more information, Ceva, together with PixArt will host a live webinar, Spot-On Dead Reckoning for Indoor Autonomous Robots, April 27th, 2021 at 11:00 a.m. U.S. Eastern/ 08:00 a.m. U.S. Pacific.
