Introduction

As one of the first professional robots that we used here at Unchained Robotics, the Denso Cobotta is near and dear to our hearts. Not only does it have a very cute and friendly design (and demeanor!), it is an incredibly capable cobot.

In the early days at Unchained Robotics, we used the Denso Cobotta a lot. It’s so light and user friendly that it proved to be the perfect platform for a large number of experiments and tests. Among other things, we created a use case where the Denso Cobotta served as a Barista! You could place an empty cup in front of it wherever you’d like, and the robot would find it, bring it to the machine, select the roast, make the coffee, and bring it back to you.

See the video here:

Company

The company behind the Cobotta is Denso Robotics. As a subsidiary of Denso Corporation, Denso Robotics is part of one of the world’s largest companies. And they’re no industry newcomers. As of writing this, Denso has sold over 120,000 robots all over the world. To say that Denso is an industry leader would be an understatement.

Founded and based in Kariya in Japan, Denso is a leading manufacturer of robots in a country known for its robots. The Denso Cobotta is their light-weight collaborative robot offering that combines functionality and ease of use into one extremely light-weight package.

Features

The Cobotta itself is one of the smaller professional cobots on the market. With a reach of 342mm and a payload capacity of 0.5kg, the Cobotta is definitely not going to win on brawn alone!

But this little Cobot can do a lot and has a number of features that make it extremely attractive for a wide range of applications.

Small payload, tiny weight

The Cobotta can only lift 500g, it’s true. However, the cobot itself only weighs 4kg. So, it can be easily transported just about anywhere. The average person can easily carry a Denso Cobotta or two! (However, we’d recommend only carrying one at a time, and doing so very carefully).

Its low weight makes it the idea robotic companion on table or countertops that might not be able to handle the stress of a larger cobot solution. Its compact size also means that it doesn’t take up much space, making it the ideal tabletop companion for labs.

The Denso Cobotta is also notable for the fact that its control unit is actually built into the base. So not only does it have a very small footprint, but that footprint also includes a large part that is usually housed externally on other robots.

Right on the mark

Despite its compact size, Denso didn’t sacrifice speed or accuracy. The Denso Cobotta is accurate to within 0.5mm. Its default speed is 0.5 m/s, but it can reach a composite speed of up to 1 m/s. The latter being the standard speed for collaborative robots.

A whole new world – Cobotta App

The Denso Cobotta may be a lightweight physically, but when it comes to software, it’s a heavyweight. Its tablet application allows the user to program a large variety of processes and functions without ever having to leave the GUI!

Further, Denso made the Cobotta software open source, this means that if you really want to dig down into the software and build an extremely customized solution almost from the ground up, then there’s nothing stopping you!

With the Cobotta, Denso tries to strike the perfect balance between ease of use and adaptability. Most processes can be programmed without coding knowledge, but if you do have that knowledge the world – eh, or at least the cobot – is your oyster.

Integrated Camera

If the Cobotta had a philosophy, it would be to make everything as easy as possible without giving up any customizability.

In that vein, Denso includes a very capable and easy-to-use integrated camera. However, if you don’t want to use the camera, then you don’t have to!

Integrated Gripper or BYOG

Likewise, the Denso Cobotta also includes an integrated gripper solution. This simple, two-finger gripper is durable and practical, but perhaps doesn’t meet the needs of your specific application.

In this case, you can bring your own gripper and built an End-of-Arm solution that is adapted to your process.

Denso Cobotta Use Cases

So, what is the best use case for the Denso Cobotta? There are a number of potential use cases, but as one can probably gather from the Denso Cobotta’s sleek white design, the laboratory is definitely its preferred habitat.

Tending petri dishes, managing slides, manipulating test tubes – these are all applications for which the Denso Cobotta would be a perfect fit.

Outside of the lab, the Denso Cobotta would be a good fit for a myriad of tabletop applications.

About this series

This is part of an ongoing series where we introduce you to our robots! At Unchained Robotics we offer a large array of robots, each with its own strengths and ideal work environment. In order to help you get to know our robots and discover which one is the ideal match for your specific task, we’re undertaking to introduce one of our robots per week.
