Lab Equipment

The Srivastava Senior Design Lab has a wide selection of equipment that provides nearly all of the capabilities of the other ECE teaching labs in one place. Although the equipment may not be identical to that found in these other teaching labs, similar functionality is offered. Use the experience of learning new equipment as a way to expand your horizons. If you are using a piece of equipment for the first time, ask a TA for assistance, to make sure you understand how to safely use it. If the available equipment does not meet the needs of your project, talk to the course staff, and we will help you find what you need elsewhere on campus, consider purchasing it for the senior design lab (if it would be used by many groups), or brainstorm alternate ways to solve your problem.

Lab Kits

Each team is provided with at least one lockable storage drawer in the lab as well as a portable lab kit. An additional drawer and/or kit may be issued as need arises and facilities allow.

The lab kit includes a box with carrying handle and contains a wiring board for prototyping circuit projects, a multiple-output power supply, a digital multimeter, and a set of 8 cables (2 bnc/bnc, 2bnc/pin, 2 banana/banana, and 2 banana/pin). This is checked out to you by your TA at the beginning of the semester and must be returned undamaged at the end of the semester. Missing lab kits will result in an encumbrance or withheld diploma and a charge of $500.00, so always be sure to lock your lockers! Also, do not store any cables from the lab in your kit. Doing so will result in a loss of points.

Test Equipment

Most equipment is connected to the PCs via HPIB cables. Below is a sampling of the test equipment available:

Specific setups at the various lab benches can be in the listing at the bottom of this page.

Computers

The lab has PCs with enough processing power for the needs of nearly any senior design project. These machines are networked to a high-capacity laser printer (printing will count against your standard print quota). Each has an Ethernet connection to the campus network, an HPIB interface card connecting it to all of the standard instruments on its bench, and a sound card. The computers are maintained by Engineering IT, located in 3080 ECE Building.

The PCs are presently configured with the software shown here. Their primary uses include:

Low Cost Myoelectric Prosthetic Hand

Low Cost Myoelectric Prosthetic Hand

Featured Project

According to the WHO, 80% of amputees are in developing nations, and less than 3% of that 80% have access to rehabilitative care. In a study by Heidi Witteveen, “the lack of sensory feedback was indicated as one of the major factors of prosthesis abandonment.” A low cost myoelectric prosthetic hand interfaced with a sensory substitution system returns functionality, increases the availability to amputees, and provides users with sensory feedback.

We will work with Aadeel Akhtar to develop a new iteration of his open source, low cost, myoelectric prosthetic hand. The current revision uses eight EMG channels, with sensors placed on the residual limb. A microcontroller communicates with an ADC, runs a classifier to determine the user’s type of grip, and controls motors in the hand achieving desired grips at predetermined velocities.

As requested by Aadeel, the socket and hand will operate independently using separate microcontrollers and interface with each other, providing modularity and customizability. The microcontroller in the socket will interface with the ADC and run the grip classifier, which will be expanded so finger velocities correspond to the amplitude of the user’s muscle activity. The hand microcontroller controls the motors and receives grip and velocity commands. Contact reflexes will be added via pressure sensors in fingertips, adjusting grip strength and velocity. The hand microcontroller will interface with existing sensory substitution systems using the pressure sensors. A PCB with a custom motor controller will fit inside the palm of the hand, and interface with the hand microcontroller.
