What we do

We are interested in developing robotic prototypes and practical control algorithms that would push the state-of-the-art of current systems. We use prototyping tools such as 3D printers and simulations and tools in system identification, optimization, feedback control, and learning. Please see videos for a sampling of the systems we work on.


  Joining the Lab

If you are a current UTSA undergraduate student (Freshman to Senior) or graduate student (Masters and PhD) and are interested in joining our group please email Pranav Bhounsule, pranav.bhounsule AT utsa.edu 

    For UTSA Masters student - It is recommended that you join the lab early, ideally, in your first or second semester. The earlier you join, the higher are your chances of doing well at MS Thesis/project. I normally dont fund a Masters student unless he was worked with me before or has done very well in one of my courses.

    For UTSA undergraduates - If you are looking for Senior Design Project and/or Independent study project, please get in touch. For Independent study, you need to have a GPA > 3.3 to meet the ME Dept. cut-off and be a Junior or Senior. It would be ideal if you have taken a class with me before, but not required.

If you are a high school student in San Antonio and looking for a research experiences in Robotics in summer please email Pranav Bhounsule, pranav.bhounsule AT utsa.edu

If you are NOT a current UTSA student and are interested in joining our group you will have to first be admitted to UTSA. For Masters and PhD students you need to apply to the graduate school. After you get admitted to UTSA please email Pranav Bhounsule, pranav.bhounsule AT utsa.edu. I do not make admission decisions, but the graduate committee does, and so I cannot comment on your chances of getting admitted.

  Lab Location

The Lab is located in Biotechnology, Sciences and Engineering Building (BSE) 2.216. The nearest parking garage is Ximenes Ave. Garage. GPS address: Ximenes Ave. Garage, Ransom Road, San Antonio, Texas 78249. (google map link)

P. A. Bhounsule, "A controller design framework for bipedal robots: Trajectory optimization and event-based stabilization", PhD Thesis, Cornell University, Ithaca, NY, USA, May 2012.

The thesis led to two world records on legged robots in 2011 which have both been broken in 2015 (see below):

1) The robot walked non-stop for 40.5 miles or 65 kms on a single charge without being touched or recharged (Click for video)

This record has been surpassed by Chinese robot Xingzhe No.1  in 2015 walking a distance of 83 miles (~ 134 km) in 54 hrs.

2) The same robot (in a seperate trial) walked with Total Cost of Transport (TCOT = Energy used per unit weight per unit distance travelled) of 0.19 and marginally better then 0.2 achieved by Collins walker. Note that humans have a TCOT of 0.32. (Click for video)

This record has been surpassed by robot Cargo (Fumiya IIda) in 2015.  Robot Cargo achieved a TCOT of  0.1.

  Outreach

We have done STEM (Science, Technology, Engineering, and Math) related outreach at local schools and the children's museum in  San Antonio. We typically do 2-3 such events every year. Here are some example outreach events.

1. Workshop on creating paper-based walking toys at the San Antonio Children's Museum. (Photo link).

2. Demonstration of various robots created in the Robotics and Motion Lab. (Photo link).

3. Kids tele-operating LEGO robots. (Video link)

4. LEGO Robotics outreach at UTSA. (Video link)
