The use of robotics in industrial and other applications has resulted in large improvements in efficiency and safety. Robots are able to perform tasks that are repetitive, unsafe, or for any other reason are undesirable for humans to carry out. Simulation has been used extensively in the fields of robotics research and industrial robotic applications, and being able to study the interaction of control systems with mechanical behavior is invaluable for any type of development in this area. Simulation can be used to test the feasibility of new robotic concepts or increase the performance and efficiency of existing applications.
MotionPort and RecurDyn in Off-Road Vehicle Research
A new robot concept with two sets of tracks seems to hold a lot of promise for urban reconnaissance. A military research group was asked to simulate the mobility of the robot in climbing a set of stairs. They could not do the simulation, although they were experienced with tracked vehicle simulation with a leading simulation software. A university research partner knew of the need of the military research group and also knew of RecurDyn. MotionPort staff quickly developed a model with over 1,700 degrees of freedom were able to demonstrate the stair-climbing maneuver (photo courtesy of JPL Robotics).
- Model: Robot with four track assemblies
- Robustness Advantage: Ability to model stair climbing
