An introduction
Robot
• What • Why• When
Main Applications
• Industry• Industry• Industry
Videos here
Primary sections
• Mechanical• Electronics• Coding
Exercise(DIY Robot)
• Mobot ( Mobile Robot )• Task: Transport a small toy car from point A to
B. Distance 10m.• Weight of car to be 2 KGs • Time , not a factor.• Car dimensions: 300mm * 200mm *200mm
Mechanical
• Chassis • Manipulators • End effecters
Chassis
• Rigid body on which everything else is mounted
• No moving parts • Rigid material
Manipulator
• Actuators types– Motors – Pneumatics– Hydraulics– Electromagnetics– etc
End effectors
• Grippers– Pneumatic grippers– Hydraulic – Vacuum – Electromagnetic
Electronics
• Sensors • Power electronics
PS: Feedback concept
• Feedback• Pros and cons
Sensors
• Proximity sensors• Positional sensors• Heat• Light• Orientation sensors
Power supply
• Drivers, relays• Power supply according to power required by
members• Electronics members will explain(sorry)
Coding
• Binary, Hex, etc.• Algorithm writing • Function development• Integration with other bodies
Algorithm
• Simple flowchart or written format describing activity
• Identify switches, yes no conditions, etc
Function Development
• Delay• ADC• PWM
Integrate with bodies
• Test all systems before installation, before mechanical systems are made
Divide class here
Bot design Overall
• Brainstorming sessions• Discuss strategies • Discuss limitations
Finalize design
• Find faults • Find problems• Finalize temporarily
Mechanical department
• Material selection • Structure design on paper, and then on CAD
soft wares ( PRO E, CATIA, etc.)• Simulations if possible in softwares.
Electronics
• Decision on types of sensors to be used • Decision on power supply to be used• Decision on controller to be used ( with coding
team)
Coding
• Decision of controller selection• Formation of basic functions required and
testing of the same• Coordination with electronics team for coding
inputs and solutions
Brainstorming session
• Discussion if design with rest of team.• Helps with finding glitches overlooked.• Fresh eyes view valuable.
Break
(Thinking break)
Mechanical department
• Design finalization• Solutions
Electronics
• Sensor finalization• Power supply solution
Coding
• Finalizations of strategy to be used • Functions to be used
Summarising
Problems in the solution
