FROG at NEMO

IMG_2650In June 2016, students from the UT took the Campus robot to the NEMO Science Museum in Amsterdam. They were using the red FROG as a robot platform to demonstrate their project work, part of the R3D3, the Rolling Receptionist Robot with Double Dutch Discourse project.

For the project, an array microphone was temporarily fitted to the red FROG so that it could pick up questions asked by visitors to the museum. Due to the high noise levels they encountered the, otherwise successful, project used a Wizard-of-Oz set-up to answer questions. The results of the project will help in the further development of the R3D3 receptionist robot.

 

 

Laser upgrade for protoFROG

The guys got together again!

Although they are now all working on different projects, Randy and Jan  keep in  touch with Noé via Skype and Facebook and, sometimes, after office hours they still find time to work together on one of their favourite FROG robots.

1Recently Jan and Randy fitted 2 extra lasers to cover some blind spots at the sides to FROG – this meant they had to make holes in the shell (shhh ….. nobody tell Paulo!).

2The extra lasers allow protoFROG (aka the Campus Robot) to navigate better through spaces and some corners inside its new seasonal home, the DesignLab.

There, HMI Masters‘ students are using FROG as a platform for researching receptionist robots as part of the R3D3 project (part of the Dutch national COMMIT program).

protoFROG at a standstill at Hannover Messe

The UT Campus robot is having some problems at the Hannover Messe. On the first day it drove around until lunchtime but now protoFROG is at a standstill. This is an outdoor robot with a lot of traction power and the loose-laid carpet is causing the motors to overheat during rotation. Although, by the look of it there is not always that much room to manoeuvre, anyway.

The FROG robot was defined to run outdoors, specifically for the EU project in the Lisbon Zoo and in the Royal Alcázar in Sevilla. As the robot must not only navigate the various terrains at these sites but also be able to turn on the spot the project has been having some difficulties with their choice of tires. What would you choose for a  100 kilo robot that has to handle clean-swept tarmac and paving, either of which may later be strewn with olive stones from the trees. This is the terrain in the Lisbon zoo – and the robots mission also includes some inclines and ramps. Then move the same robot to Sevilla where it has to go from neat paved courtyards onto tiled or marble floors.

And in the past two weeks, protoFROG has had to cope with gravel strewn tarmac, TV studios, and now, loose-laid carpet. That’s a lot to deal with for a prototype.
