String Differential
Aim -
To develop a new Mars rover differential mechanism which improves upon the shortcomings of the bar differential mechanism
Motivation -
The string differential was an ongoing project at Team Anveshak being passed on from one year to the next. For the year 2019-20, I worked on a revamped implementation to overcome the shortcomings of the previous iteration while being guided by a senior team member. For the year 2020-21, I am guiding the string differential project.
What I learnt -
-
Workflow from ideation to design to prototype manufacturing
-
Relatively involved design and simulations on Fusion 360
-
Ensuring ease of manufacturing (through laser cutting and bending) without compromising on functionality
Progress and Current Status -
-
Design completed
-
Prototype manufactured
-
Issues recognised
-
Currently guiding the next iteration
Rough Timeline -
-
Ideation and design : June-Nov 2019
-
Components manufactured : Dec-Feb 2020
-
Testing : March 2020
-
Commencement of next iteration ideation : June 2020
