AUTONOMOUS ELECTRIC CART

Newcastle University, 2019

  • Designed, manufactured, programmed, and tested a small cart. The cart was equipped with multiple sensors which were used to make the cart autonomous in nature.

  • The cart was manually controlled by a joystick and was able to go autonomous mode at any given time.

  • The cart was equipped with SONAR, IMU, Encoders, Light Sensor and Limit Switch.

  • Using the sensors, the cart was programmed to autonomously navigate a few obstacle tracks.

  • PID Control was used for the cart.

  • The cart had a battery pack to power the electronics and motors.

  • The cart also had adaptive cruise control and many other assistive and safety features programmed in.

  • The cart used a magnetometer (IMU) to know its orientation to correct its path.

  • C++ language was used for programming.

HARDPOINT MEASURING SYSTEM WITH ADJUSTABLE TEST RIG

Gestamp, 2019

  • Designed a Hard Point Measuring System with Adjustable Test Rig which can adjust to the inaccuracies measured by the Hard Point Measuring System for Gestamp.

  • Adjustable Test Rig had three attachment points with rigid frame capable of taking about 100 kN.

  • Each attachment point had 4 degrees of freedom adjustments i.e. x-axis/y-axis/z-axis/rotation about one of the axes.

  • The assembly was >1 meter tall with an adjustment accuracy of <1mm.

  • The Hard Point Measuring System was designed to measure inaccuracies down to ± 0.1mm.

  • The assembly was tested in ANSYS for possible deformations and strength and optimised to suit the application.

  • The assembly was designed such that it could be cheaply manufactured. (Flame cut - Fabrication - Machining)

Newcastle University, 2019

  • Designed and manufactured the strongest point-load bridge in the University.

  • Performed hand calculations and stress analysis on the CAD model of the Bridge.

  • The bridge was designed to fail before 3 kN failure load; failed at 2.75 kN.

  • Lead the team of 4. 

  • Manufactured using only 0.9 mm thick sheet metal aluminum and riveting.

  • Manufactured the whole bridge within 5 hours of team-work.

CRANE HOOK IN SHEET METAL

Newcastle University, 2019
