Students and the teaching faculty of Srinivas Institute of Technology
(SIT) have developed two innovative electronic devices - automated
prosthetic leg and drawing robot.
To help physically challenged
persons, final year mechanical engineering students - Abins Michael,
Bonskey Samuel, Anoop Raj Rao and Clifford Aranha ---- under the
guidance of project coordinators Neelakantha V Londhe and Sharathchandra
Prabhu have developed the automated prosthetic leg.
This device is helpful for those who find it difficult to move their
legs. The device reduces the effort required for walking by physically
challenged persons.
Explaining how this device functions, students said the energy required for the movement of prosthetic leg is supplied by a compact 12 volt battery, which is fixed on the back of the waist belt of a physically challenged person. A small motor generates the movement of prosthetic leg, which is made of wood and aluminum, they said.
Each cycle of prosthetic leg movement involves three steps - first is to lift the thigh along with lower limb, then stretching of the lower limb and finally pushing back the entire leg forward or backward as required by the user.
Performance of the device can be enhanced using microcontroller. After charging the battery, this device can be used continuously for four hours.
Sharathchandra Prabhu told TOI: "Since we did research before designing this device, the cost to develop it was Rs 14,000. But the estimated manufacturing cost would be around Rs 6,000." To design this device for needy people, students have started approaching hospitals in this region, said Sharathchandra.
Drawing robot
Four final year computer engineering students - Janeeval P James, Jithu Sebastian, Margrette Thomas and Mobin KB -- under the guidance of computer science professors Janardhan Bhat K and GS Shivkumar have designed a drawing robot, a device which draws complicated civil engineering and machineries drawings.
Drawing robot will draw any type of pictures and shapes which is entered in android enabled mobile phone. This robot with a pencil holder is made of steel and fibre. The user of this device has to just connect robot with an android mobile phone through Bluetooth. Then user has to enter size and shape of the picture and the picture will be transferred from mobile to Arduino UNO - a microcontroller attached to the robot. With the help of microcontroller, robot will draw image specified by the users.
GS Shivkumar, who is also the head of department of computer science engineering, said this robot is useful to engineers as it draws complicated pictures of machineries with accuracy. "We spent around Rs 10,000 to design this robot," he added.
