Dextrous Robotics, a Memphis-based startup that developed a chopstick-like robotic to unload bins 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. Nevertheless, the corporate was unable to shut one other spherical of funding to start out manufacturing on the business 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 at least one factor, I might level to the enterprise markets,” he added. “COVID warped investing into startups. When rates of interest are low, individuals must search for longer-term investments that may pay them higher than what they will get by conventional devices. When rates of interest are excessive, a startup’s short-term profitability must be increased. 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 personalized. It used few off-the-shelf components. 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 keep in mind what number of conferences I took the place individuals 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 might inform they had been not . From 2019 to 2022, we didn’t hear any concern concerning the BOM in any respect. However in 2023, that was a unique story.
“Buyers needed to understand how quickly our startup may very well be worthwhile,” he mentioned. “We caught with our aggressive, longer-term trajectory, and that didn’t pan out. Greater than some 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 through the top 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 one of these utility. We had been grateful to get seed funding, however we didn’t notice how uncommon a possibility it’s for a market to highlight the problems your expertise is fixing. Now, VCs aren’t writing as large 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 gained 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.” Nevertheless, 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’ll be able to’t function on that,” they mentioned.
Evan Drumwright mentioned Dextrous explored being acquired to offer the buyers some returns. However they didn’t begin that course of early sufficient.
“Having by no means carried out this earlier than, we didn’t notice individuals begin turning into liable if we continued into insolvency,” he famous. “Earlier than we made individuals 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’ll be able to watch that video on the high of this web page.
The DX-1 options two inflexible chopstick-like robotic arms that every have 5 levels of freedom. The towers that help every arm journey on separate gantries that permit Cartesian motion. The system grabs bins from a number of sides and applies regulated strain to understand 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 gadgets as small as a sugar dice and as massive 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 supply funding advised Dextrous they had been going to attend and see how the competitors unfolds.
Pickle not too long ago 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 programs all use a variation of suction-based grippers to control bins, not like Dextrous’s chopstick-like manipulators that grasped every field from two sides. Every method has its execs and cons, however maybe the chopstick method was too completely different.
“The chopstick method was pretty apparent,” recalled Evan Drumwright about how Dextrous landed on this method. “When you discuss humanoids, their fingers are simply not enough. These anthropomorphic fingers are far much less succesful than a human hand. So that you want one other kind of device.”
“And the pinching robotic grippers gained’t work right here both due to the scale and form disparity of the bins,” he mentioned. “So this is the reason individuals went with suction, which has its personal execs and cons. Intelligence and chopsticks can carry a whole lot of issues — our thesis was confirmed.”
There’s demand for a lot of these robots. Sadly, Dextrous couldn’t grasp the chance.
Strategically situated in Memphis
Dextrous strategically picked Memphis for its headquarters. Memphis is likely one of the main logistics hubs within the U.S. Dextrous hoped its robots can be utilized by the nationwide and worldwide logistics corporations primarily based there. In Might 2023, Dextrous relocated to a bigger constructing in Midtown Memphis.
Clearly, issues didn’t go based on plan.
Evan Drumwright claimed Dextrous had a wholesome firm pipeline inside logistics and retail.
“No person has an answer to this complete downside,” he mentioned. “That’s to not say we’d be an ideal match for everyone. For some prospects, the suction method is ideal. However the majority of outlets, producers, 3PLs, and package deal logistics corporations cope with 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 number of weeks is being proud,” mentioned Suzanne Drumwright. “With beneath $10 million, a workforce of 10 constructed a robotic that makes use of chopsticks to unload transport containers. Is it too revolutionary, is it too completely different? We heard plenty 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 certain, however one other robotics startup is actually 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 adore it if we had been centered on fulfilling contracts with the large prospects we had lined up, however the truth we put this collectively and made it work like we hoped to is an efficient second prize.”
