The TU Delft Bicycle Simulator

The TUDelft Bicycle Simulator, version 2, Jan 2017. Characteristics are: virtual environment by Unity, visual feedback by a screen (1th and 3rd person view) or by a head mount display (oculus rift), haptic torque feedback on the handle bars driven by a Carvallo/Whipple bicycle computer model, roll angle only …

Oliver Lee Presents Results on the State Bicycle Simulator

Oliver Lee successfully presented some results on the usage of our static bicycle simulator at the International Cycle Safety Conference in Hannover, Germany (ICSC2015). One of the characteristics of the Static Bicycle Simulator is haptic feedback on the handlebars driven by the bicycle simulation model. Another aspect is that it …

Moved to the New Lab Space

This month the bicycle lab moved to the new lab space (room 4A-1-04) which is on the first floor, close to our offices. We are very happy with the new lab; more than 80 m2 of light and clean space with lots of room for table-top experimental setups and …

Calspan Bicycle Reports

After many years of searching and negotiating we are now able to post a selection of the Calspan reports on Bicycle and Motorcycle Dynamics research. Thanks to the effort of Jim Papadopoulos and Doug Milliken!


LEGO Mindstorms NXT Based Bicycle Robot

Joep Mutsaerts builds a LEGO Mindstorms NXT based bicycle robot in an assignment for the TUDelft 3mE/PME course Mechatronic System Design II. The lateral stability control is done by the concept of "steer into the undesired fall" and comes down to only one line of code in the controller …



Full Motion Capture of Bicycle Riding on a Treadmill

Jan 9-11, 2009: For three days we have been doing full motion capture of the rider and the bicycle while riding on the large(3X5 m) VU Amsterdam treadmil. This to investigate rider motions on a bicycle. The Optotrack Certus Motion Capture System with active markers was used (thanks to …

Exploratory Tests on the VU Treadmill

Today we did a number of exploratory tests on the big VU treadmill (3X5m) to have a first look at human rider control. The bicycle was a Batavus Browser town bicycle which was prepared by Jodi and Jason and is equipped with sensors for: steer angel, steer rate, rear frame …

Instrumented Bicycle on the VU Treadmill

Today we put the instrumented bicycle from Jodi' MSc work on the big VU treadmill. We feel more confident about the usage of this treadmill for our bicycle handling experiments if the instrumented bicycle on the treadmill shows the same lateral dynamic behaviour as on the road. It turned out …
