College Robotics

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

Q&A sessions
