Price on application
What the model is designed for
Specify the arm or manipulation configuration, controller, mounting and end effector. Confirm whether vision, computing and software are included or separate.
What your task may need
A working task needs suitable tooling, workspace setup, programming and testing with the actual objects. Assess load and reach against the complete task.
Software & connections
Confirm the supported computer, operating system, accounts and developer access. Ask what runs on the robot, on a nearby computer or in the cloud; what stops without internet; and whether subscriptions or remote assistance are needed.
Setup & ongoing support
Richard helps clarify the package and coordinate supplier enquiries. Specialist setup, programming, diagnosis and repairs need a capable supplier or technical partner. That support is not yet agreed for every model; the provider, scope and fees must be confirmed before an order.
What is included in your package?
The exact contents depend on your chosen edition and supplier quote. Ask for an itemised list of included equipment, optional extras and anything you need to supply yourself.
Six things to settle in your written package
- The box and the extras
- Exact model and edition; quantities of batteries, chargers, controller, cables, hands or grippers and sensors. Mark each item as included, optional, supplied by you or not required. Confirm the UK mains arrangement.
- Your first useful task
- Separate supplied functions from demonstrations and custom development. Agree the software, operator involvement, working conditions and a simple acceptance test for your task.
- Computer, software and connections
- Confirm the supported computer, operating system, accounts and developer access. Ask what runs on the robot, on a nearby computer or in the cloud; what stops without internet; and whether subscriptions or remote assistance are needed.
- Transport, storage and running time
- Plan space for the robot and its equipment, suitable protective packaging, charging time and the manufacturer’s storage instructions. Check battery transport requirements before arranging travel or a return.
- A named route to help
- Name the technical provider and agree setup, training, fault diagnosis, response hours, repair location, return freight and warranty handling. Record what is included and what costs extra.
- Parts and total cost
- Check the exact replacement part, evidence of fitment, availability and who may install it. Itemise delivery, import charges where relevant, software, accessories and support alongside the robot price.
This is a package-planning service. Included equipment, price, delivery and support are confirmed in writing before an order.
Expectations / your working setup
Is your workplace ready for this robot?
For Unitree R1-7a, confirm these five points against the exact hardware, software and task in your quote. Published specifications elsewhere on this page are a starting point; your working setup still needs to be agreed.
Status: configuration and site checks required. An unanswered question means unconfirmed, not unsuitable.
01 / Where will it charge — and when?
Confirm the approved UK charger or mains supply, location, measured runtime under the intended load, charge time and any supported battery-swap arrangement. Fit charging and checks around the working day. A maximum runtime claim is not a shift plan.
02 / What keeps working if the internet drops?
Separate onboard control, a local computer and cloud services. Ask what happens if Wi-Fi, internet or the external computer fails, and what is needed to recover. Confirm setup, normal operation, task software, updates and fleet tools separately.
03 / Does workplace information leave the premises?
Ask about video, audio, maps, logs and training data: where they go, who can see them, retention and deletion, and whether uploads can be disabled without losing the required function.
04 / Can the supplier access or operate it remotely?
Distinguish diagnostics, camera access, updates and motion control. Agree permission, named accounts, time limits, logs and a way to revoke access. Confirm the support route if remote access is not allowed.
05 / What else must we provide and pay for?
List computers, controllers, networking, grippers, safety equipment, licences, subscriptions, training and human supervision. Name the support provider and agree response times, warranty handling and repair arrangements. Richard can coordinate; specialist technical support must be agreed with a capable provider.
See how companies develop a specific robot task ↗
Understand who is doing what
Remote control
A person directs the robot. This can be a useful demonstration or research tool, but requires an operator.
Programmed task
The robot repeats a prepared sequence. Objects, positions and the work area may need to stay consistent.
Autonomous task
The robot makes defined decisions within a tested task and environment. Check its limits, supervision and recovery when something goes wrong.
Manufacturer films show particular tasks and configurations. Confirm the operating mode, software and operator involvement for the application you are considering.
Plan the whole package
Useful before you choose
Compare other starting points
Compare the exact version, equipment and task requirements. These are alternatives to investigate, not confirmed substitutes.
01 / UNDERSTAND THE HARDWARE
Get closer.
See what matters.
Select a numbered topic to understand the systems behind the robot. These are explanatory controls, not service or disassembly locations.
01 / ARTICULATION
An extra joint changes the options.
Seven axes give more ways to orient the tool around a task. Avoid treating this as proof of any specific collision-free path or workcell performance.
Figures describe the manufacturer’s stated configuration. Confirm the exact hardware, software and included equipment for your project.
02 / REACH
Read the endpoint definition.
The 650 mm maximum reach explicitly includes a dexterous hand in the source. Confirm the measured reach of the exact selected tool and mounting position.
Figures describe the manufacturer’s stated configuration. Confirm the exact hardware, software and included equipment for your project.
03 / INTERFACES
Hardware and software must agree.
The listed interface is XT30+CAN485, with Ubuntu and position/force control. Request connector pinouts, bus details and released software versions.
Figures describe the manufacturer’s stated configuration. Confirm the exact hardware, software and included equipment for your project.
04 / LOAD
Keep the first project focused.
The arm is listed at 2 kg payload and around 5.5 kg self-weight. The manufacturer warns that control tuning can affect positional error and oscillation.
Figures describe the manufacturer’s stated configuration. Confirm the exact hardware, software and included equipment for your project.
02 / SIZE & SPACE
Picture the platform.
Plan the space.
Body dimensions are a starting point. Moving joints, handling, attachments and a clear operating area need additional room.
Robodromo explanatory schematics. Not to scale, not CAD and not clearance or fitment drawings. Labels follow the stated source; unknown measurements remain unknown.
03 / CHOOSE THE CONFIGURATION
The details change
the possibilities.
The model name is only the start. Compare the hardware, development access and package before choosing a robot.

06 / FROM HARDWARE TO A USEFUL PROJECT
Start with a task
you can test.
Laboratory manipulation experiments.
Write down what success looks like, which data or controls you need, and who will build and support the software. A capable robot and a complete working application are different purchases.
A specific task, environment, payload and measurable result.
The exact firmware, APIs, examples and development permissions.
Robot revision, tools, sensors, power, setup and support.
07 / LIFE WITH THE ROBOT
A complete decision.
A clearer first step.
Our starting points below are selection notes. Final suitability depends on the exact package, the task and the people responsible for it.
The supplied kit
Get an itemised packing list covering the robot revision, battery, charger and UK mains arrangement, controller, tools, sensors and computing. Images can show optional equipment.
The first session
Plan the operating area, supervision, stopping procedure and setup. Follow the actual supplied manual and allow time for familiarisation before a public demonstration.
Running costs
Include spare batteries, charging, software accounts, network charges and maintenance in the plan. Confirm which functions depend on external services.
Support after delivery
Agree who diagnoses faults, where repairs happen, who pays freight, which genuine parts are available and how long software support is expected.
Where we would start
- Laboratory manipulation experiments.
- Robotics education with an appropriate fixed mounting arrangement.
- Dual-arm research after the system architecture has been agreed.
Before we recommend an order
- Confirm the exact hardware, software and included equipment.
- Define a practical test of the intended task.
- Agree UK delivery, setup, support and the complete price.
08 / PRACTICAL QUESTIONS
Before you choose.
Is all the software already open source?
The page describes progressive releases. Confirm the exact repositories, versions and licence before committing.
What is the torque at each joint?
The public table contains an inconsistent label. We need a corrected torque specification rather than republishing it as fact.
Is a dexterous hand included?
The reach figure mentions one, but that is not a packing list. The end-effector must be confirmed in the offer.
What is the Robodromo UK price?
