Product Description

Update: This limited edition item is no longer available.  We are making room for the newer, second generation T8X!  

If you're interested in this 3D printed version instead of the T8X, we may still be able to get you one; contact us at sales@robugtix.com. 


T8 is a bio-inspired high resolution 3D printed robot that uses a total of 26 servo motors.  It is powered by the Bigfoot™ Inverse Kinematics Engine.

The Bigfoot™ Inverse Kinematics Engine handles all the complex math calculations necessary for controlling multi-legged walking robots.  All computations are safely hidden from the user in the form of a black box.  This means that the user only has to send short and simple commands to the robot (for example, instructing it to walk forward at a desired speed) and the engine will automatically take care of all the details, including inverse kinematics, leg trajectory planning, leg gait coordination, motor control, etc.  This makes it quite easy even for absolute beginners to play with advanced robotics.

Commands are sent and received via wireless XBee. Optionally, you can connect your own serial communication method with the provided Rx/Tx pins.

You can choose between pre-programming your own sequences or directly controlling the robot in real time with the wireless Robugtix™ Controller.

A Heavy Duty Protective Case for T8 is available for purchase as a separate accessory.

The T8 spider robot is shipped 98% pre-assembled and fully calibrated!

What's included:

  • A complete set of high resolution 3D printed parts of the T8
  • T8 microcontroller board pre-loaded with the Bigfoot Inverse Kinematics Engine
  • 26 Hitec HS-35HD servo motors
  • Fasteners and miscellaneous mechanical parts

NOTE: Batteries are not included.  Requires a single 4xAA 4.8V NiMH rechargeable battery pack.  Complete details regarding power supply requirements are available in the documentation below.

The Robugtix™ Controller and wireless XBee modules are not included in this kit.  These are highly recommended items to include along with the purchase of this kit since it is the easiest and most convenient way to communicate with the robot.

  • The pre-order discount has ended.
Friday, 2013-Sep-01:
  • The shipping fee has been changed from 1kg to 4kg for each T8.  The weight of the package itself has not changed by much, but shipping is also calculated by volume and we've decided to increase the box size to be able to protect the product even better with extra bubble wrap!  Customers who pre-ordered with a 1kg shipping fee will be upgraded to 4kg at no additional cost.  This change applies only to new orders.
Monday, 2013-Sep-30:
  • Over the past few months, we have received emails asking if a pre-assembled version was also available for purchase.  We've now made the decision to officially have all T8 spider robots ship 98% pre-assembled with the servo motors fully calibrated!
  • Stay tuned to our Robugtix YouTube Channel for new videos to be released soon of the T8 in action!
  • We are getting ready to ship!  Shipping of the pre-ordered T8 robots is scheduled to begin on Monday, October 7th, 2013 and will continue on until the end of October 2013.  Because of the unexpectedly high number of T8 pre-orders made during the pre-order period (July and August of 2013), they will be shipped on a first pre-ordered first shipped basis.  We will do our best to make sure you have it in your hands before Halloween.

  • We have just passed 50% of pre-orders shipped!  If your pre-order was shipped, an email with tracking number has been sent to you.
  • We are currently waiting on another bulk shipment of HS-35HD servo motors from our Hitec supplier, originally planned to arrive mid-October.  Delays from the supplier were due to natural disaster hitting their production facilities.  We were informed that the remaining supply of servo motors is expected to arrive in November 2013.  We apologize to approximately 30% of the pre-order customers who will probably not receive their T8 spider robot before Halloween.

Tuesday, 2013-Nov-12

  • More servo motors arrived at our facilities and more T8 spider robots have been shipped.  We have now passed 85% of pre-orders shipped.  If your item was shipped, a tracking number has been emailed to you.  Awaiting more shipments of motors from our Hitec supplier.

  1. Amazing 5 Star Review

    Posted by on 7th Mar 2014

    As a robotics hobbyist and an engineer , I find this robot amazing, first of all , out of the box all you need to make it work is just a 4 cell NIMH battery and a USB connection to power the controller ,so if you have no idea how to program these multi-legged robots and trust me its not an easy task to do as you need to calibrate , work on the IK and wrap all that into a fail proof product is not an easy task at all, I can't imagine all the hours the programmers at Amoeba Robotics had to put to make this robot come to life ,The t8 has 3 types of gaits that you can easily switch between using the controller and its motion is so natural and organic that it might freak others out because it looks very realistic ,the only downside is that this robot frame is not the toughest and you must be very careful while handling it but other than that , I don't think there is any better looking or better programmed out of the box octopods out there and I would definitely recommend it to others.

  2. The T8 is everything I hoped it would be 5 Star Review

    Posted by on 20th Oct 2013

    From the second I opened the shipping box, I knew I had purchased a winner. The light weight was the first thing I noticed. I've been trying to build my own hexapod using a 3D printer, but never came close to balancing the body weight with the servo power. The T8 moves extremely well. It is extraordinarily fast and has a large repertoire of moves that make it very realistic. I sent Robugtix an email requesting more details regarding the batteries for the body. I received an immediate response that included a complete answer to my question and a detailed photo of the battery configuration. You don't expect that kind of service response from every company you deal with. I was so pleased with the product, I ordered a second controller. Good job Robugtix.
