A Truly Modular Robotic Kit


Be mindful your childhood, when a bucket of Lego bricks was like having infiniteammo in your creativeness? Rising up doesn’t suggest it is necessary handy over these moments. The reality is, now you need to use your creativeness and make stuff that is far more sophisticated and has much better capabilities. On this text, we concentrate on an fascinating bundle that will will help you create a myriad of robotic constructions to hold out assorted options.

Merlyn TRN-1
At its best, it is a robotic bundle that helps you design as a lot as 28 a number of forms of fundamental robots, be it a linear shifting robotic, rotary robotic arm or maybe a robotic with cylindrical axis. In case you dig beneath the ground a little bit of, it is a totally modular, digital, rugged bundle that not solely lets you create robots however moreover helps you add new choices to them. This one bundle permits an unlimited array of prospects to create, administration and reconfigure robots—wha-ever be the need.

It is principally a gadget, the parts of which might be connected collectively to create any type of motion. You can add your widespread items to this gadget. The perfect half is that it’s worthwhile to use it to hold out options required for industrial automation—such is the flexibilit of this machine.

This bundle is the brainchild of Biju Ronnie Varkey, proprietor of Designs and Duties Enchancment (DPD), Patiala. A robotics fanatic himself, Varkey labored on this product for two prolonged years, making certain that it is constructed and options exactly the way in which during which it is meant to be.

On asking what drove this idea in his ideas, Varkey says, “While teaching robotics at engineering colleges, I noticed that there was nothing available at hand to teach students in a way that they would not only remember but also enjoy learning robotics. The most I saw anywhere was a couple of microcontrollers, line follower robots and the like. I sincerely felt that this was a huge waste of engineering talent and hence I started working on this project two years ago by designing and then fine-tuningthe initial design according to the feedbacks I received from students and teachers, who are as much responsible for the finaldesign as anyone who worked on it.”

“Apart from generating an interest in robotics, I also wanted students, who come out having learnt the basics of robotics, to be able to say that they had an employable education,” he offers.

Choices of Merlyn TRN-1
The bundle is principally divided into three parts: electronics, which includes microcontrollers, motors and drivers for motors; mechanical half, which incorporates the entire axes; and software program program section, which controls microcontrollers used inside the bundle.

The bundle makes use of a stepper motor for movement alongside the entire axes, along with the rotary axis that has a geared set-up. The motor used is a 2A stepper motor with unbiased drivers for each of the motors. These drivers are managed by a microcontroller; in case of TRN-1, an Arduino Mega 2560 board. You may even drive it by connecting it to your PC or laptop computer pc.

“Using an Arduino board provides a good number of inputs/outputs (useful for attaching a number of sensors) and is also easy to program, highly stable and extremely flexible.Stepper motors can easily be replaced with DC motors or servo motors, and all of them can be controlled directly by the board without much fuss,” Varkey says.


The Arduino board is ready to driving as a lot as eight axes (eight stepper motors) on the an identical time. Due to this fact your system has spherical eight ranges of freedom. You can add a proximity sensor, IR sensor or what-ever suits you. The completely totally different motors are con-nected to at least one one other to help the robotic switch the way in which during which you need.

Each of the three parts of the bundle might be customised to an incredible diploma, enabling simple functioning and lending good frequency to the robotic that you just must design.

Talking in regards to the points encountered by means of the materialisation of the thought, Varkey says, “Since the idea was already in my head after the visits to engineering colleges, I spent a lot of time listening to the target users of our system, making notes of the problems they were facing, what they wanted and things they wanted in the solution. Then, it took us nearly a year to reach the point where we are today. This model is actually based on the 10th prototype we rolled out. The firstone we made could only be turned into a single basic robotic system.”

“To add value, Merlyn TRN-1 was worked on extensively to enable it to be turned into 28 fundamentally different types of robotic systems. You can cascade different kits together to increase the envelope in which you are working along with the range/scope of the work you are doing. The best part is that you are not limited by the mechanical, electronics or software scheme of things utilised in the robot,” he offers.

The components have been significantly comprised of anodised aluminium, guaranteeing a rugged however delicate design.
