I have research space in two laboratories at the University of Alberta.
Room 4-28, Mechanical Engineering Building
Our research group has dedicated laboratory space with 3 m ceilings and high floor loading capability as a work & testing area for machinery diagnostics projects, embedded systems development, and robotics and UAV projects for remote asset monitoring and industrial environmental monitoring.
Equipment includes a four-bar linkage driven by a VFD-controlled 1-hp AC motor through a Spectraquest gearbox. The system is currently being used for controlled what testing studies with controlled normal forces of a stylus on coupons. This apparatus can be used as a shovel emulator that imparts external forces on a nonlinear mechanical device for system identification studies with disturbances. The system can also be configured with a brake, and alternative transmissions such as belt drives. A fixed machine bed acts as a table for a Unholtz-Dickie Model 20 shaker table for structural and machinery vibration studies.
Robotic systems include a modified hydraulic-drive Quadrover mobile robot, a heavily modified Clearwater Husky mobile robot with payloads for soil characterization, including an active trundle wheel with a 6 degree-of-freedom force-torque sensor. Other payload include remotely operated soil samplers that can be deployed several metres into soil. A DJI s1000+ octocopter is used for remote condition monitoring, with payloads such as MEMS vibration sensors, 3 FLIR infrared cameras, an A-scan ultrasonic thickness transducer, and sampling tools. Several smaller quadcopters are also available. There is a two-degree-of-freedom gantry system to emulate indoor motions.
A number of wireless embedded sensor systems allow biaxial strain measurement at >150 Hz (very useful for wireless shaft torque measurement), resolvers, differential GPS location (there are other IMUs as well), thermistors, etc. Data acquisition instrumentation includes two 16 channel Bruel & Kjaer vibration monitoring systems, twelve triaxial B&K accelerometers, Labjack computer 4 interface with Toughbook computer. The vibration monitoring system is packaged in a Pelican case and is completely portable as well as fairly weatherproof. There is also a modal analysis hammer.
There are four workstations for embedded systems prototyping, a 3D printer, and an electronics table for sensor fabrication and data acquisition system testing.
- Horizontal End Mill for tire damage studies
- Vibration Table (capable of 30 kN of force at 100 Hz on a 1 m x 1 m surface)
