Dextrous Robotics, a Memphis-based startup that developed a chopstick-like robotic to unload packing containers from trailers, has shut down. Evan Drumwright and Sam Zapolsky based Dextrous in 2019, and the corporate dissolved in late December 2023.
Dextrous had raised about $8 million in funding since its inception. Nonetheless, the corporate was unable to shut one other spherical of funding to start out manufacturing on the industrial model of its DX-1 robotic.
“There are such a lot of issues that must go proper for a startup to succeed,” Evan Drumwright advised The Robotic Report. “We knew that going into it. Not that it makes this any simpler.”
“If I needed to level to 1 factor, I might level to the enterprise markets,” he added. “COVID warped investing into startups. When rates of interest are low, folks must search for longer-term investments that may pay them higher than what they will get by way of conventional devices. When rates of interest are excessive, a startup’s short-term profitability must be greater. It was going to take us some time to construct as much as profitability.”
Suzanne Drumwright, director of operations at Dextrous Robotics, mentioned the DX-1 robotic is totally custom-made. It used few off-the-shelf elements. This drove the invoice of supplies (BOM) to greater than $300,000 per unit. Evan Drumwright observed a change in how buyers reacted to Dextrous’ BOM in late 2022.
“I don’t bear in mind what number of conferences I took the place folks requested what the BOM was,” mentioned Evan Drumwright, who was a senior analysis scientist at Toyota Analysis Institute earlier than founding Dextrous. “As soon as I mentioned the quantity, it didn’t matter how that tied into income. You can inform they had been now not . From 2019 to 2022, we didn’t hear any concern in regards to the BOM in any respect. However in 2023, that was a distinct story.
“Buyers needed to know the way quickly our startup might be worthwhile,” he mentioned. “We caught with our aggressive, longer-term trajectory, and that didn’t pan out. Greater than every other issue by far, rates of interest being excessive has modified the funding calculus.”
Hindsight being 20/20, Suzanne Drumwright mentioned Dextrous ought to have raised extra money in the course of the peak of the COVID-19 pandemic.
“If we raised extra money throughout COVID, that will’ve been useful,” she mentioned. “That point was a shining mild on the necessity for such a software. We had been grateful to get seed funding, however we didn’t understand how uncommon a possibility it’s for a market to highlight the problems your know-how is fixing. Now, VCs aren’t writing as huge of checks or as many checks.”
The Robotic Report reached out to a few of Dextrous’ buyers for remark however hadn’t heard again by press time.
Dextrous additionally received a $999,746 grant from the Nationwide Science Basis in September 2023 for a mission entitled “Automated Notion for Robotic Chopsticks Manipulating Small and Giant Objects in Constrained Areas.” Nonetheless, each Evan and Suzanne Drumwright mentioned the grant is paid out in $250,000 chunks over two years and must be earmarked for sure initiatives.
“You possibly can’t function on that,” they mentioned.
Evan Drumwright mentioned Dextrous explored being acquired to provide the buyers some returns. However they didn’t begin that course of early sufficient.
“Having by no means achieved this earlier than, we didn’t understand folks begin turning into liable if we continued into insolvency,” he famous. “Earlier than we made folks liable, we shut down operations.”
How Dextrous’ robotic labored
We first talked to Drumwright in 2020 for an episode of The Robotic Report Podcast. On the time, Dextrous exited stealth mode and was prepared to debate its proof of idea, which used Franka Panda cobot arms.
Simply six months in the past, the corporate launched a video of its second DX-1 prototype. You possibly can watch that video on the prime of this web page.
The DX-1 options two inflexible chopstick-like robotic arms that every have 5 levels of freedom. The towers that assist every arm trip on separate gantries that permit Cartesian motion. The system grabs packing containers from a number of sides and applies regulated stress to know packages weighing as much as 100 lb., Dextrous mentioned.
Customized sensors allow the DX-1 to detect and transfer packages. Dextrous mentioned its robotic may decide 2,000 parcels per hour, in addition to manipulate objects as small as a sugar dice and as giant as an armchair. Evan Drumwright beforehand mentioned he envisioned the robots increasing into markets past logistics, together with agriculture and manufacturing.
Elevated competitors additionally a problem
One other problem that Dextrous bumped into was elevated competitors. Boston Dynamics, Dexterity, Pickle Robotic Co., Rightbot, Mujin, and others are creating robots for trailer loading and unloading. Evan Drumwright mentioned a number of buyers who declined to offer funding advised Dextrous they had been going to attend and see how the competitors unfolds.
Boston Dynamics has discovered early success with its Stretch robotic that’s being deployed by the likes of DHL, NFI, Otto Group — which had been all multi-million greenback contracts.
Pickle just lately introduced Yusen Logistics as a buyer. Yusen mentioned it unloads 200,000 containers yearly. Mujin has raised $104 million in Collection C funding, and Rightbot picked up $6.25 million from Amazon.
These aforementioned methods all use a variation of suction-based grippers to govern packing containers, in contrast to Dextrous’s chopstick-like manipulators that grasped every field from two sides. Every method has its professionals and cons, however maybe the chopstick method was too totally different.
“The chopstick method was pretty apparent,” recalled Evan Drumwright about how Dextrous landed on this method. “When you speak about humanoids, their arms are simply not enough. These anthropomorphic arms are far much less succesful than a human hand. So that you want one other kind of device.”
“And the pinching robotic grippers received’t work right here both due to the scale and form disparity of the packing containers,” he mentioned. “So that is why folks went with suction, which has its personal professionals and cons. Intelligence and chopsticks can carry loads of issues — our thesis was confirmed.”
There may be demand for all these robots. Sadly, Dextrous couldn’t grasp the chance.
Strategically situated in Memphis
Dextrous strategically picked Memphis for its headquarters. Memphis is among the main logistics hubs within the U.S. Dextrous hoped its robots can be utilized by the nationwide and worldwide logistics firms based mostly there. In Might 2023, Dextrous relocated to a bigger constructing in Midtown Memphis.
Clearly, issues didn’t go in accordance with plan.
Evan Drumwright claimed Dextrous had a wholesome firm pipeline inside logistics and retail.
“No one has an answer to this complete downside,” he mentioned. “That’s to not say we’d be an ideal match for everyone. For some clients, the suction method is ideal. However the majority of outlets, producers, 3PLs, and bundle logistics firms take care of some a lot variation in dimension, form, and payload that there wasn’t an answer in existence or on the horizon that would compete with us.”
“We’re each bummed, however the overwhelming feeling after sitting on it for a couple of weeks is being proud,” mentioned Suzanne Drumwright. “With underneath $10 million, a crew of 10 constructed a robotic that makes use of chopsticks to unload delivery containers. Is it too revolutionary, is it too totally different? We heard a lot of cheering from the sidelines that it labored.”
Evan Drumwright mentioned they’ve secured Dextrous’ IP again from buyers. As for what’s subsequent? They’re not precisely positive, however one other robotics startup is definitely not out of the query.
“We’re tremendous pleased with what we constructed,” Evan Drumwright mentioned. “Going into it, we needed to construct one thing utilizing this chopstick method and transfer issues at excessive speeds in dynamic environments. And we did it. I might find it irresistible if we had been targeted on fulfilling contracts with the large clients we had lined up, however the truth we put this collectively and made it work like we hoped to is an efficient second prize.”
