PhantomX Reactor robot arm kit for entry level research

$630.00 ex vat

The PhantomX Reactor robot arm kit is the flagship of Trossen’s Arbotix based ROS ready research grade robotic arms.

Designed with a focus on reach and agility, PhantomX Reactor offers considerable strength for an arm of its size with a payload capacity of up to 250g.  Equipped with Dynamixel actuators to support up to 300° of motion resulting in a significant range of motion and reach. Temperature monitoring, positional feedback, as well as voltage levels, load, and compliance settings are user accessible as well.

This highly specced, low-cost product is feature-rich and ideally suited for entry-level research and university use, with four kit types available to best suit your application – with wrist rotate, no wrist rotate, no servos and barebones.

Rugged metal frame construction and 14cm diameter ball bearing rotational base ensure rigidity and accuracy while optional ‘wrist rotate’ allows for up to 5 degrees of freedom, along with a custom-designed parallel gripper for high precision and maximum gripping strength.

The Reactor Robot Arm has up to a 43cm horizontal reach and 55cm of vertical reach. At a 10cm reach, it can lift up to 600g, and at 30cm up to 200g. The gripper has a holding strength of up to 500g, while the wrist itself can lift up to 250g horizontally (150g if using wrist rotate).

The onboard Arbotix Robocontroller can be programmed using the Arduino IDE or custom firmware, providing eight digital and analogue IOs, Xbee wireless or USB connectivity, and a powerful ATMega644p capable of handling Inverse Kinematics code onboard.

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.
