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. Nevertheless, 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 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’d 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 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 personalized. 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 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 could possibly inform they had been not . From 2019 to 2022, we didn’t hear any concern concerning the BOM in any way. However in 2023, that was a special story.
“Traders wished to understand how quickly our startup could possibly 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 more cash throughout the top of the COVID-19 pandemic.
“If we raised more cash throughout COVID, that may’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 expertise 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 challenge entitled “Automated Notion for Robotic Chopsticks Manipulating Small and Massive 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 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 finished this earlier than, we didn’t understand individuals begin changing 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 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 experience on separate gantries that enable Cartesian motion. The system grabs packing containers from a number of sides and applies regulated strain 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 might 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 growing robots for trailer loading and unloading. Evan Drumwright mentioned a number of buyers 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 mentioned it unloads 200,000 containers yearly. Mujin has raised $104 million in Sequence C funding, and Rightbot picked up $6.25 million from Amazon.
These aforementioned programs all use a variation of suction-based grippers to control packing containers, 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. “If you happen to 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 sort 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 for this reason individuals went with suction, which has its personal execs and cons. Intelligence and chopsticks can carry a number of issues — our thesis was confirmed.”
There may be demand for a majority of these robots. Sadly, Dextrous couldn’t grasp the chance.
Strategically positioned 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 based mostly there. In Could 2023, Dextrous relocated to a bigger constructing in Midtown Memphis.
Clearly, issues didn’t go in response to plan.
Evan Drumwright claimed Dextrous had a wholesome firm pipeline inside logistics and retail.
“No one has an answer to this whole drawback,” 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 package deal logistics corporations 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 a number of weeks is being proud,” mentioned Suzanne Drumwright. “With beneath $10 million, a staff of 10 constructed a robotic that makes use of chopsticks to unload delivery containers. Is it too modern, is it too completely different? We heard a number 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 wished to construct one thing utilizing this chopstick method and transfer issues at excessive speeds in dynamic environments. And we did it. I’d like it if we had been centered 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 effective second prize.”
