Aliengo – robust, high performance quadruped robot

Contact us for pricing

Designed as a research platform, Aliengo is a high-performance quadruped robot that can traverse uneven terrain, climb gradients of up to 21° and remain stable even if kicked, all at a maximum speed of 1.5 m/s for up to 4 hours on a single charge.   An integrated depth perception vision system enables real-time 3D map creation and navigation planning, along with human posture recognition tracking and face recognition.

An impressive payload capacity of 10 kg, combined with a rich external interface and ROS support, make sensor integration with this robot dog simple and straight forward.  While incredible agility and a range of special movements, including backflips, creeping and lateral locomotion, allow Aliengo to navigate complex environments.

Depth vision – real-time 3D map creation and navigation planning

3D environment construction – while in motion Aliengo uses the cameras to obtain colour and depth information of the environment, then reconstructs the 3D spatial information of objects with the help of a specific vision algorithm.

Probability map – octomaps / probability maps are created bu the cameras as the robot moves, detecting surroundings and providing obstacle data.

Dynamic obstacle perception – when the robot encounters a dynamic obstacle it refreshes that map data within a particular range, discarding the ‘moving artefact’ left by the dynamic obstacle on the map.

Global positioning – global and local real-time positioning functions are available during the process of map creation.  The map will follow the camera’s perspective in real-time, supporting real-time zoom, movement and rotation.

Loop detection – Aliengo maintains high loop-back accuracy in a wide range of fields, high positioning accuracy within a certain range, maintaining stability with a certain oscillation amplitude, with drift or loss.

Human posture recognition tracking and face recognition

Body posture recognition – Aliengo’s deep learning module enables the colour camera to identify specific human postures and conduct human-machine interaction, the robot can then make movements that correspond to different body postures.

Human skeleton perception – the robot can analyse and calculate the two-dimensional skeleton information of the human body according to colour information from perspective, and analyse and calculate the three-dimensional skeleton information and motion of a specific character using depths of field.

Target person tracking – when multiple pedestrians are present, Aliengo can be instructed to lock on to an individual by a particular posture (eg raising the left hand), the robot will then follow the movement of the target,

Loan finance

Level Five Supplies is pleased to offer finance as a payment option, iur appointed partners can work with you to make equipment purchase more straightforward.

There are many reasons to consider using finance:

  1. Improves Cash Flow: When you finance your equipment, your cash isn’t tied up in the equipment. Instead, it’s free for other investments that will grow your business, produce income, and ensure the equipment you acquire earns profits over its lifetime.
  2. Preserves Other Lines of Credit: Tomorrow can bring many opportunities. Financing equipment means you’ll have the credit available (either from the bank or other sources) to take advantage of future opportunities.
  3. Hedges against inflation: Your monthly payment remains the same over the term of the lease or loan. Money paid later in the term usually have less purchasing power than those paid at the beginning of the term…so you pay for today’s equipment needs with tomorrow’s lower-value currency.
  4. Provides 100% financing: Even “soft costs” such as training, shipping, installation, and maintenance agreements can usually be included. So you can rest easy knowing that these associated costs won’t disrupt your cash flow.
  5. Simplifies equipment changes: Hiring additional workforce? Increasing efficiency? Additional equipment can easily be added to your existing loan or lease. Or, if you’re trying to stay ahead of the competition by staying ahead of technologies, the equity in your financed equipment can be applied toward the loan or lease of new equipment. These options solve the problems of obsolescence – and make your job easier.
  6. Eliminates hidden charges: You have no compensating balances, no closing costs, and no blanket liens or other restrictive covenants that banks use to increase customers’ cost. What you see is what you get.
  7. Offers excellent rates: Our finance partner rates are highly competitive.
  8. Saves on taxes: Depending on the type of finance agreement you select, as much as 100% of your payments may be tax deductible.
  9. Offers many payment programs: Our finance partners work for you, not us. You choose the type of loan or lease that best fits your needs, and you select the length of the loan or lease term.

The finance agreement is between you and the lender, and we don’t take commission or referral fees – but we’ve done the preparatory work of allocating a broker for the US, and another for Europe, explaining the technology, validating supplier products and explaining how the technology will be used so your application process is simplified and focused entirely on the financials.

The initial part of the process usually takes less than an hour and means that you can spread the cost of a higher value purchase of equipment like this over several months or even years, allowing you to better plan your project or department budgets, but also means you can get what you need over the coming years, not just what you can afford today.
