by Andrew Kickertz Introduction to using Blender / Bullet to detect and respond to collisions of rough elastic bodies, particularly bowling pins and balls. For the past few months I have been developing a Matlab-based bowling-oriented physics engine for simulating the collisions of balls and pins, as well as the … Continue reading
by Jason Moore This is a description of an identification procedure for the bicycle based around the benchmark canonical form. Model structure The identification of the linear dynamics of the bicycle can be formulated with respect to the benchmark canonical form realized in [Meijaard2007]. Mq¨+vC1q˙+[gK0+v2K2]q=T where the time varying states … Continue reading
by Kenneth Lyons Overview and results of a calibration routine for determining the position of the index line on the steer encoder. For the last few weeks, I have been working with Luke to produce a steer calibration program to run on the robotic bike. Much of this time … Continue reading
by Andrew Kickertz Collision detection via meshes, and rough calculation of post-impact velocities. Over the past couple weeks I’ve been developing a method to detect collisions between pins, modeling them as meshes. I’m also thinking about describing the pins as parametric surfaces, but that’s another can of worms. The radius … Continue reading
by Jason Moore I’d like to share my dissertation work at an upcoming conference, but ASME wants the copyright. What do I do about it? I’m wrapping up my dissertation (moorepants.github.com/dissertation) and want to present some of the material in it at some upcoming conferences in my field. One that … Continue reading
by Jason Moore I’ve made some progress on viewing the results of my bicycle model identification. This is a summary of the current state. I’m about to start writing up the results I’ve obtained on identifying a linear bicycle model. As I’ve explored the data, my confidence growing in it … Continue reading
by Jason Moore I’ve been working on a small application to visualize and interact with the data resulting from identifying the bicycle model from all of my data. This is a preliminary look at how it is coming along. I’m using the basic grey box identification technique as described … Continue reading
by Jason Moore Two new students are collecting data with the instrumented bicycle. Elliot and Ziqi are two new graduate students in our lab and they have been learning about bicycle dynamics and getting familiar with using and collecting data with the instrumented bicycle. They’ve been doing some slalom experiments … Continue reading

by Jason Moore There are some tools in Matlab that don’t exist in Python. How can I seamlessly make use of Matlab tools with Python? I’ve been making use of Matlab’s System Identification toolbox extensively, as there really isn’t anything on the open source market that does the same kind … Continue reading
