Introduction Gomer is an educational robot, especially designed to introduce advanced features like artificial intelligence (AI) and computer vision (also known as machine vision) in the classrooms. Gomer, which falls under the category of smart robot, is designed and manufactured

by GLI Technology Limited, Shenzhen (China).

Gomer provides a hands-on platform for the school students to learn topics in computer visions, pattern recognition and AI, and experience the AI-based reallife product right in the classroom. The programmability evolves in stages, enabling students from different grades to participate in working with Gomer and creating real-life solutions involving computer vision and AI-based automation. This further helps in enhancing their design-thinking and analytical skills, and practicing creativity in the STEM topics.

Key features / capabilities The Gomer robot is equipped with AI and bunch of sensors facilitating: •

Face recognition Based on AI technology, Gomer can recognize not only your face but also can learn to identify your facial expressions. This enables creating a personal autonomous interaction with Gomer – Gomer can recognize you and say hello or play a welcome tune.

•

Pattern recognition Gomer comes with built-in database of few patterns such as alphabets, numbers and blocks.

This library of images or pattern database can be further enhanced with custom images and patterns to develop automated solutions.

•

Precise movements and a perfect grip Gomer comes with precise movement of the body and arms for creating a wide range of projects involving pick-and-place activities. An award-winning grip system lets you program the Gomer to pick up wide range of objects from a strawberry, eggs to a solid wooden block or even a soda can.

•

Sketchpad for customizing Gomer expressions Through programming interface, students can create custom expressions (in the form of sketches) for Gomer. This takes the automated interactive programs to the next level.

•

Text-to-speech

P age |4

Mu kesh Soni Mu kesh Son i

Make Gomer speak your language! Programming interface allows you to enter text that can be spoken by Gomer. A fancy solution to customized interaction with Gomer!

•

Ease of programming Gomer can be programmed using block-based graphical programming (suitable for primary school students) and Python scripts (an object-oriented, open source programming language for students at advanced stage).

Programming Tool The Gomer requires an app to program it. The app, also known as Gomer, is available for Android or iOS mobile devices.

Android (Google play) - https://play.google.com/store/apps/details?id=com.glitech.gomer iOS (Apple iPad/iPhone) - https://itunes.apple.com/us/app/gomer-the-robot/id1281990367?mt=8

Note: Make sure that you provide all the necessary permissions to the app while installing it on your mobile device (phone or tablet).

Connection / setup guide Before you program or interactively control the Gomer, you need to establish connection between Gomer robot and the mobile app. Here are the steps: 1. Ensure the Gomer robot is turned on – You can turn it on by pressing the button on the front.

2. Open the mobile app. It will show you how to connect the robot to the app. There are two ways to connect to the Gomer for programming or controlling it: a. Direction connection over Wi-Fi hotspot offered by Gomer (AP mode) b. Connection through a Wi-Fi router common to both Gomer and the mobile device (STA Mode) 3. From the following screen, you can connect directly to the Gomer Robot’s Wi-Fi hotspot by clicking on “Tap”.

4. Clicking on “Tap” opens the wireless connection setting on your mobile device. Now connect to the “Gomer” Wi-Fi using password/key (8-times eight) as shown on the screen of Gomer Robot.

5. To connect in STA mode, where both your mobile device and the Gomer robot are on the same wireless network, you need to “skip” the “connection” screen and click on the “Settings” icon on the main page of the app.

6. Scroll to the right for “Connection Type” information on the “Settings” page.

P age |6

Mu kesh Soni Mu kesh Son i

7. Click on the “STA” connection type, then fill out your Wi-Fi settings on next page and press “Done”.

8. You can use the “connection type” page under the “settings” to switch between two types of connections – STA or AP mode.

Overview of the Gomer App Gomer app enables interaction with Gomer Robot. Using the app as a remote, you can simply control the robot like a toy; or you may try built-in demo functions that showcase the robot’s capabilities. The app also contains a system for programming the robot to create autonomous applications.

P age |7

Mu kesh Soni Mu kesh Son i

The “program” section of Gomer app is based on Google Blockly, a jig-saw puzzle like graphical programming environment especially designed for education. The library contains functional blocks that can be dragged-and-dropped in the workspace area, and logically joined together to create a program.

Library functions The instruction blocks are organized under different functional categories called libraries. For example, the “Driving” library contains all the necessary functions to move the Gomer robot

P age |8

Mu kesh Soni Mu kesh Son i

forward or backward by a fixed distance or turn it right or left by specified angle. Similarly, the “Emotion” set of blocks lets you set the expression of the robot.

Following are the library functions available on the Gomer app: • •

Driving – Forward, backward movements and left, right turns Posture – Preset postures involving arm and wrist positions or individual control of arm, wrist, head and grip

• •

Expression – Showing custom sketches on robot display Sound – Text-to-speech or voice recording to be played in the robotic tone

• •

Emotion – Emotional expressions involving robot display, posture and movements Skill – Set of predefined complex tasks like hand-shake, automatic grabbing or pattern detection

P age |9

Mu kesh Soni Mu kesh Son i

• • •

Logic – Events, loop, decision branching or wait blocks for programming Math – Logical and mathematical operators Variables – Variable creation, definition and manipulation

With this overview, we are all set to create programs and control the Gomer robot.
