In case you’ve ever talked to the oldsters at Tangram Imaginative and prescient, chances are high you got here away extra educated concerning the state of notion for robotics. The workforce on the Boulder, Colo.-based startup has 60-plus years of mixed expertise with notion and sensors.
Based in 2020, it has developed a toolset to assist roboticists resolve notion issues reminiscent of multimodal sensor calibration, sensor fusion and sensor uptime. And now it’s making its first foray into robotic notion {hardware} with a 3D depth sensor known as HiFi that packs a robust AI punch as nicely.
HiFi launched on Kickstarter with early backers capable of get a HiFi for $349, which is 36% off the $549 retail value. Tangram surpassed its $25,000 purpose 4 hours after launching it; at press time, the marketing campaign had raised greater than $40,000. Tangram expects to ship the primary HiFi models in April 2024.
The Tangram Imaginative and prescient workforce got here out of Occipital, the spatial computing firm that launched the Construction Sensor 3D sensor with a $1.3 million marketing campaign on Kickstarter in 2013.
“Instruments for robotics and AI have come a good distance previously few years, however sensors haven’t saved tempo,” mentioned Brandon Minor, CEO, Tangram Imaginative and prescient. “After talking with lots of of robotics and AI engineers, we knew they needed to spend much less time battling sensors and extra time constructing cool merchandise. HiFi makes it lifeless easy so as to add AI-enhanced 3D information to robots and extra.”

HiFi’s capabilities
HiFi makes use of ams Mira220 cameras. It combines a 136° discipline of view 2-megapixel world shutter IR stereo pair with a 136° discipline of view 2-megapixel RGB digicam and twin lively projectors. A 65mm baseline delivers depth from 0.3m to 5m with 30-60 frames per second. Due to its discipline of view, Tangram mentioned roboticists can exchange two depth sensors with a single HiFi in lots of functions.
HiFi features a host of software program, drivers and onboard instruments for roboticists. For instance, it’s designed to natively work with ROS 2. It comes with 8 TOPS of machine studying processing energy that allows on-sensor fusion of AI and 3D information. It additionally has 8GB of onboard reminiscence that Tangram mentioned permits neural networks to be run onboard HiFi.
It contains a devoted depth processor on the Texas Devices (TI) Jacinto chip. Tangram mentioned the Jacinto processor lets HiFi supply compatibility with the TI’s Deep Studying Library that comes with ready-to-deploy fashions for scene segmentation, pose estimation, object identification, object monitoring and extra. HiFi additionally comes outfitted with Tangram’s sensor software program instruments like self-calibration, time sync, and uptime administration.

Robotics functions
Tangram advised The Robotic Report it by no means had any intention of creating a 3D sensor. However it mentioned it was compelled to take action after so lots of its robotics prospects expressed disappointment with the state of 3D sensing.
“Proper now, robotics engineers should select between 3D information high quality, AI capabilities, or reliability. However they actually need all three,” mentioned Minor.
In a testimonial for the HiFi marketing campaign, Nathan Brooks, CTO of PickNik, seemingly agreed. He mentioned his firm has “been speaking with Tangram for years and sharing a few of our pains in deploying robotic functions in the true world and unstructured environments.”
Rodnitzky mentioned cellular robotics has traditionally been Tangram’s bread and butter. However he mentioned HiFi will allow the corporate to work with various kinds of robots and functions.
“Bin-picking functions didn’t make sense for us earlier than, however now they do,” he mentioned. “This might permit us to additionally dip our toes into industrial automation the place Zivid, IDS and Cognex have dominated with costlier sensors.”
Market alternative
To know the chance Tangram envisions for HiFi, simply take a look at the volatility of the depth sensor market in recent times. The Kinect was as soon as a stable possibility, however that died when Apple acquired PrimeSense for $360 million in 2013. Google shut down Undertaking Tango in late 2017 after a promising three years. And Intel almost shuttered its RealSense division earlier than deciding to proceed introducing new depth sensors.
Tangram doesn’t have the dimensions of these aforementioned corporations. However Minor doesn’t assume that’s a difficulty.
“I don’t know if of us belief these bigger gamers. There’s threat there as nicely,” he mentioned. “We don’t have as many mouths to feed, and this could possibly be game-changing for the trade and our firm.”
Minor additionally mentioned promoting HiFi is a chance for Tangram to introduce its calibration companies, and its recurring income mannequin, to corporations which have by no means heard of it earlier than.
“We launched Tangram to decrease the barrier to entry into laptop imaginative and prescient,” mentioned Minor. “That’s why we began with calibration – it’s an not possible activity that’s very onerous to do. HiFi is yet one more piece of that puzzle. Allow us to construct a sensor that meets depth information high quality requirements and comes with wonderful AI processing capabilities to do subtle processes. And roboticists can give attention to functions and what they do nicely.”
