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. Nonetheless, the corporate was unable to shut one other spherical of funding to begin manufacturing on the industrial model of its DX-1 robotic.
“There are such a lot of issues that need to go proper for a startup to succeed,” Evan Drumwright informed 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 need to search for longer-term investments that may pay them higher than what they’ll get by means of 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, stated the DX-1 robotic is totally custom-made. 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 traders reacted to Dextrous’ BOM in late 2022.
“I don’t bear in mind what number of conferences I took the place individuals requested what the BOM was,” stated Evan Drumwright, who was a senior analysis scientist at Toyota Analysis Institute earlier than founding Dextrous. “As soon as I stated 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 way. However in 2023, that was a unique story.
“Traders wished to know the way quickly our startup might be worthwhile,” he stated. “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 stated Dextrous ought to have raised extra money throughout the peak of the COVID-19 pandemic.
“If we raised extra money throughout COVID, that may’ve been useful,” she stated. “That point was a shining gentle on the necessity for the sort of software. We had been grateful to get seed funding, however we didn’t notice how uncommon a chance 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’ traders 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 undertaking entitled “Automated Notion for Robotic Chopsticks Manipulating Small and Massive Objects in Constrained Areas.” Nonetheless, each Evan and Suzanne Drumwright stated the grant is paid out in $250,000 chunks over two years and must be earmarked for sure initiatives.
“You may’t function on that,” they stated.
Evan Drumwright stated Dextrous explored being acquired to offer the traders some returns. However they didn’t begin that course of early sufficient.
“Having by no means completed 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 may 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 enable Cartesian motion. The system grabs bins from a number of sides and applies regulated stress to know packages weighing as much as 100 lb., Dextrous stated.
Customized sensors allow the DX-1 to detect and transfer packages. Dextrous stated its robotic might choose 2,000 parcels per hour, in addition to manipulate objects as small as a sugar dice and as massive as an armchair. Evan Drumwright beforehand stated 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 stated a number of traders who declined to offer funding informed 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 stated 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 bins, not like 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 palms are simply not ample. These anthropomorphic palms are far much less succesful than a human hand. So that you want one other sort of device.”
“And the pinching robotic grippers gained’t work right here both due to the scale and form disparity of the bins,” he stated. “So because of this individuals went with suction, which has its personal professionals and cons. Intelligence and chopsticks can elevate a number of issues — our thesis was confirmed.”
There’s demand for these kinds of robots. Sadly, Dextrous couldn’t grasp the chance.
Strategically positioned in Memphis
Dextrous strategically picked Memphis for its headquarters. Memphis is without doubt one of 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 whole downside,” he stated. “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 bundle logistics firms cope with some a lot variation in measurement, 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 just a few weeks is being proud,” stated 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 number of cheering from the sidelines that it labored.”
Evan Drumwright stated they’ve secured Dextrous’ IP again from traders. As for what’s subsequent? They’re not precisely certain, however one other robotics startup is definitely not out of the query.
“We’re tremendous pleased with what we constructed,” Evan Drumwright stated. “Going into it, we wished 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 massive 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.”
