On 26 October 2026, ROKAE Robotics announced it had shipped its 10,000th force-controlled humanoid-grade robotic arm. For most UK procurement managers, the name ROKAE is unfamiliar. That is exactly the point.
When a Chinese robot manufacturer nobody has heard of ships its 10,000th unit of a humanoid component in under three years, it is a signal worth paying attention to. Mass production of force-controlled arms has arrived, and the economics of robotic arm pricing are about to shift.
This post explains what the milestone means, how it fits the historical pattern of cobot price compression, and what it implies for used robotic arm prices in the UK over the next 12 to 24 months.
> Quick Answer: ROKAE's 10,000-unit milestone signals that force-controlled humanoid-grade robotic arms are entering mass production, the same inflection point that drove cobot prices down 40 to 60% over a decade. This does not affect UK used arm prices immediately, but it puts downward pressure on new prices over 12 to 24 months, which will eventually compress used prices for comparable platforms including UR5e and entry-level industrial arms. If you need to deploy now, buy now. If you have flexibility, 2027 to 2028 may offer better value.
What ROKAE's Milestone Means
ROKAE Robotics was founded in Beijing in 2015. It is backed by Sequoia Capital China and has grown rapidly through a combination of Chinese domestic industrial demand and export-focused product development. Its product range spans standard six-axis industrial arms, collaborative robot arms (the xMate series), and force-controlled arms designed specifically for precision assembly and humanoid robot integration.
The 10,000th unit milestone is significant not for ROKAE specifically, but for what it represents about the category. Force-controlled humanoid-grade arms were, until recently, custom or near-custom components produced in hundreds of units per year by European and Japanese manufacturers at correspondingly high prices. Reaching 10,000 units across a product range means ROKAE has moved past prototype and pilot-scale manufacturing into a genuine production operation with supplier relationships, quality control processes, and cost structures that reflect volume.
To put the number in context: Universal Robots shipped its 10,000th cobot in 2016. Within three years of that milestone, UR5 prices had fallen 22% and a secondary market with genuine liquidity had formed. The cobot category as a whole followed: by 2026, a used UR5e sells for £12,000 to £17,000, versus more than £35,000 for an equivalent capability in 2012.
The pattern repeats.
Force-Controlled Arms Explained: Why They Matter for Humanoids
A standard industrial robot arm is a positional machine. It moves to a precise coordinate in space and stops. It does not know or care what it touches on the way. This is fine for welding, painting, and machine tending. It is not fine for grasping a fragile component, assembling a connector, or shaking a human hand.
Force control adds a second layer of awareness. A force-controlled arm continuously measures the forces and torques acting on its joints or end effector and adjusts its motion in response. If it encounters unexpected resistance, it backs off rather than pushing through. If a surface is not where it expected, it can comply and follow rather than jam.
This capability is central to humanoid robotics. A humanoid robot that cannot regulate contact forces will damage everything it touches. The entire dexterous manipulation challenge, the hardest unsolved problem in humanoid robotics, depends on force-controlled arms and hands working together with sensor feedback and software.
Force control is also the reason this category has been expensive. A force-torque sensor of sufficient resolution and bandwidth adds meaningful cost to an arm. Integrating that sensor into a reliable, repeatable mechanical system adds engineering complexity. Until recently, these costs meant force-controlled arms were priced at a significant premium over their positional equivalents.
ROKAE's scale removes that premium over time.
The Economics of Mass Production and Robot Pricing
Manufacturing economics are not linear. A factory producing 100 units per year of a complex mechanical system runs very different cost numbers from one producing 10,000 units per year. At 100 units, each sub-component may be custom-machined or sourced in minimum order quantities that carry a significant unit price penalty. At 10,000 units, sub-components are designed for high-volume production, and supplier relationships shift from transactional to strategic.
For a force-controlled robotic arm, the main cost drivers are the harmonic drive actuators in each joint, the force-torque sensing hardware, the motor controllers, and the structural aluminium or composite material of the arm body. All of these benefit from volume manufacturing. Harmonic drives, in particular, are manufactured at high volume by specialist suppliers and their cost drops sharply with order volume.
Chinese robot manufacturers have consistently leveraged this dynamic faster than their European and Japanese counterparts, partly because of domestic supplier proximity and partly because of willingness to accept lower margins in the early growth phase. ROKAE is following this playbook with force-controlled arms in the same way DOBOT, Elephant Robotics, and Jaka followed it with general cobots.
The result, historically, has been a 30 to 50% price compression within three to five years of a Chinese manufacturer reaching mass production scale in a given segment. There is no reason to expect force-controlled arms to be different.
Historical Precedent: How Cobot Prices Fell With Scale
Universal Robots launched the UR5 in 2009 at a price point around £35,000. It was a genuine innovation: a collaborative robot arm that could operate near humans without a safety cage, in a price bracket previously dominated by much larger industrial systems. Demand was strong but volumes were modest.
By 2014, UR had shipped 5,000 cobots. By 2016, the 10,000-unit milestone arrived. In that same period, Chinese manufacturers including Dobot, Aubo, and Rokae's predecessors entered the market with equivalent-capability arms at 25 to 40% lower price points. Competition accelerated what volume alone would have done anyway: new cobot prices fell, and they kept falling.
By 2020, a new UR5e was available in the UK for approximately £28,000. The functional capability versus the 2009 UR5 was materially better, but the price in nominal terms had fallen by 20%. In real terms, adjusting for general inflation, the price reduction was closer to 35%.
The used market followed. Once 50,000 cobots had been deployed globally, there were enough decommissions, pilot project closures, and production line reconfigurations to create a functioning secondary market with real price transparency. That secondary market now offers used UR5e cobots in the UK for £12,000 to £17,000, a 40 to 57% discount to new. The used market for all major industrial robot arms has followed similar trajectories.
The force-controlled arm category is at roughly the same position the cobot category was in 2016. ROKAE's milestone is the data point that marks the transition.
What Happens to Used Arm Prices When New Prices Fall
The relationship between new and used prices is not immediate, but it is reliable. When a new product category experiences sustained price compression, the used market follows with an 18 to 30 month lag. The mechanism is straightforward.
Used prices are anchored to new prices. A buyer will pay up to a certain percentage of new price for a used unit. That percentage tends to stay roughly constant over time (40 to 60% discount for cobots, as our depreciation data shows). When the new price anchor falls, the absolute used price falls in proportion.
Secondary effects reinforce this. As new prices fall, deployment volumes increase. Higher volumes mean more units eventually reach end-of-first-life and enter the used market. More supply with stable or growing demand keeps used prices in check.
For UK buyers of force-controlled cobots, this means:
- Existing used UR5e and UR10e prices (which already include force-torque sensing) are unlikely to be materially affected before mid-2027.
- Used Chinese cobot arms (DOBOT CR5, Elephant Robotics myCobot Pro) may see modest price softening as newer, better-specified Chinese arms compete at similar or lower new price points.
- Dedicated humanoid-component force-controlled arms (currently rare on the UK used market) will become more available as deployment volumes grow.
Current Used Robotic Arm Prices in the UK
For buyers looking for force-sensing capability in the UK used market today, the realistic options are:
| Model | Force Sensing | New Price | Used Price (UK) | Discount |
|---|---|---|---|---|
| Universal Robots UR5e | Wrist F/T sensor (built-in) | £28,000 | £12,000-£17,000 | 39-57% |
| Universal Robots UR10e | Wrist F/T sensor (built-in) | £35,000 | £15,000-£22,000 | 37-57% |
| Universal Robots UR16e | Wrist F/T sensor (built-in) | £42,000 | £18,000-£26,000 | 38-57% |
| FANUC CRX-10iA/L | Joint torque monitoring | £38,000 | £18,000-£26,000 | 32-53% |
| ABB GoFa CRB 15000 | Integrated F/T | £35,000 | £16,000-£23,000 | 34-54% |
| DOBOT CR5 | Optional F/T module | £12,000 | £4,500-£7,500 | 38-63% |
| DOBOT CR10 | Optional F/T module | £18,000 | £7,000-£11,000 | 39-61% |
These prices reflect typical UK transaction ranges as of Q4 2026. Units at the lower end of each range are older, have higher cycle counts, or are selling through auction without a warranty. Units at the upper end are from specialist UK refurbishers with a 90-day minimum warranty and full documentation.

Should You Buy Used Arms Now or Wait?
The short answer depends on your timeline.
If you have an application ready to deploy and a business case that works at current prices, buy now. The productivity gains from deploying an automated arm today compound over 12 to 24 months. Waiting for prices to fall 15% loses you that production gain, and the net financial position of waiting is almost always worse than deploying.
If you are planning a deployment 18 to 24 months out, the ROKAE milestone is worth factoring in. Force-controlled arm prices are likely to be meaningfully lower in 2027 to 2028 as Chinese manufacturers reach UK distribution maturity and European manufacturers respond with competitive pricing. A procurement plan that accounts for this may identify better value by waiting.
If you specifically need humanoid-grade force-controlled arms as components for a robotics development project, the used market for these is currently thin. Supply will improve as the first generation of humanoid deployments matures and components are refurbished or replaced. Expect better availability from 2027 onwards.
One consideration that favours buying now: the robot depreciation curve for cobots shows that well-maintained UR5e and UR10e units hold their value well. A purchase today at £12,000 to £17,000 that is well-maintained will likely resell for £9,000 to £13,000 in two years. The net cost of ownership is lower than the purchase price suggests, and the depreciation risk from a general used-price fall is partially offset by the used UR platform's strong secondary demand.
How to Spot a Good Used Force-Controlled Arm Deal
Force-controlled cobots have a specific set of inspection points beyond the standard joint and controller checks.
Confirm the force-torque sensor is functional. On a Universal Robots e-Series arm, run the wrist force-torque sensor calibration routine in PolyScope. A sensor that has been dropped, overloaded, or had its cable damaged will show zero output or erratic readings. A non-functional F/T sensor on a UR5e means you are paying cobot prices for what is effectively an older-generation UR5 capability.
Check force sensing configuration was actually used. Ask for the application log or a description of the previous deployment. A UR5e that spent its life doing simple pick-and-place with the force sensor disabled is in different condition from one that ran contact-sensitive assembly tasks at 80% of payload capacity. The former may have a good sensor with minimal fatigue; the latter requires more careful inspection.
Review joint backlash. Force-controlled applications often involve the arm making and breaking contact with surfaces repeatedly. This cycles the joints differently from free-space positional tasks. Test each joint individually by releasing the brakes and manually assessing backlash. Any joint with more than 0.05 degrees of measurable backlash warrants investigation.
Verify the safety configuration is intact. Force-controlled applications often have carefully configured safety stops and force limits embedded in the robot's safety system. Request a copy of the safety configuration file and confirm it is present. Missing safety configuration may indicate the unit has been factory-reset, which erases application context and may indicate undisclosed history.

Frequently Asked Questions
What is ROKAE Robotics?
ROKAE is a Chinese industrial robot manufacturer founded in 2015 and headquartered in Beijing. It produces collaborative robot arms, standard industrial arms, and force-controlled arms for precision assembly and humanoid component applications. ROKAE has received investment from Sequoia Capital China and is one of the faster-growing Chinese robot companies by unit volume. Its xMate series cobots compete in the same price bracket as DOBOT and Elephant Robotics products.
How much do force-controlled robotic arms cost in the UK?
Humanoid-grade force-controlled arms sell new for approximately £15,000 to £45,000. Chinese manufacturers including ROKAE price below European and Japanese equivalents by 25 to 40%. On the UK used market, cobots with integrated force-torque sensing, such as the Universal Robots UR5e, sell for £12,000 to £17,000. This represents a 40 to 57% discount to new list price and is the most accessible entry point for force-sensitive automation in the UK.
Are Chinese robot arms reliable for UK industrial use?
Yes, provided you perform appropriate due diligence. Chinese cobot brands including DOBOT, Elephant Robotics, and Jaka have established UK installation bases with documented performance histories across light assembly, pick-and-place, and machine tending applications. The critical variables for UK buyers are CE marking compliance, local service availability, and parts supply chain. ROKAE's UK distribution and service network is less mature than the established Chinese cobot brands; factor this into your purchasing decision.
How does the ROKAE milestone affect UR5e used prices?
It does not affect them immediately. The mechanism is indirect and slower-moving. When Chinese manufacturers reach mass production in a segment, they compress new prices across the category over 24 to 36 months. This reduces the new price anchor, which eventually lowers absolute used prices by proportional amounts. Used UR5e prices currently sit at £12,000 to £17,000 and are unlikely to see material changes before mid-2027 as a result of ROKAE's milestone.
What is force control in a robotic arm?
Force control is the ability of an arm to sense and regulate the contact forces it applies during motion. A force-controlled arm continuously measures forces at its joints or end effector and adjusts its trajectory in response to unexpected resistance or contact. It is essential for tasks involving fragile components, variable surface conditions, or direct human interaction. Without force control, a robot arm applies its full programmed force regardless of what it encounters, which is destructive in any contact-sensitive application.
What is the best used robotic arm under £20,000 in the UK?
The Universal Robots UR5e is the most defensible used arm purchase under £20,000 in the UK. It sells for £12,000 to £17,000 used, includes built-in wrist force-torque sensing, has a 5 kg payload and 850 mm reach, and has the deepest UK integrator ecosystem of any cobot. For a lower price point, the Dobot CR5 is available used for £4,500 to £7,500 with an optional force module. Both are available through UK specialist resellers with warranty.
When will Chinese force-controlled arm prices fall significantly in the UK?
The first meaningful price reductions for Chinese force-controlled arms in the UK are likely from 2027 onwards. Manufacturing scale is only the first step. UK distribution, CE certification, local service networks, and integrator ecosystems each add 12 to 24 months of maturation time after production scale is achieved. Buyers deploying in 2026 should proceed at current prices. Those with 18-month-plus timelines may benefit from a 2027 to 2028 purchase window.
How do I find used force-controlled robotic arms in the UK?
Robot AutoTrader lists UK used robotic arms by model, payload, and price, with condition details where available. Specialist resellers including RARUK Automation, EU Automation, and Automate-IT stock inspected and tested units with warranties. General industrial auctions including Surplex and Bidspotter periodically list arms from pilot project decommissions, often at lower prices but without warranty or documentation. For force-controlled applications specifically, the warranty route is strongly recommended: a non-functional F/T sensor is difficult to spot without specialist testing equipment.
